Configuration This chapter discusses the configuration of the DRG implementing the MotoTRBO DMR Donor Radio digital-radio interface. All web page images included in this supplement are specific to the DRG100 device; however, the web pages for the other DRG devices will be similar. This chapter includes the following sections: Viewing the System Status Digital Radio Configuration on page 3 Using the USB Port on page 8 Support for MotoTRBO Scan Mode on page 9 Viewing the System Status Select System Status on the menu to display comprehensive status information about the operation of your DRG. The information displayed on this page is read-only so you cannot make any changes. Figure 1 shows an example of the System Status page for the MotoTRBO interface when logged in under the Administrator account if you are logged in under the Technician or Limited user accounts, the information displayed will be the same; however you will not see as many menu items. Most of the information shown on this page is the same for all digitalradio interfaces supported by the DRG for further information about these values, refer to the DRG-Series Product Manual. The information that is specific to the MotoTRBO interface described in supplement appears under the Digital Radio: MotoTRBO Status section (see Digital Radio: MotoTRBO Status on page 2). MotoTRBO DMR Donor Supplement 1
Figure 1. System status page for MotoTRBO interface Digital Radio: MotoTRBO Status Figure 2 shows the typical interface information you will see for a DRG implementing the MotoTRBO interface. Figure 2. System status page showing MotoTRBO status The information displayed under the Digital Radio MOTOTRBO Status section includes the following: 2 Configuration
USB Device shows the status of the USB device and whether the DRG is communicating with it correctly. The normal status for the USB device is Connected. Radio shows the status of the connected radio and whether the DRG is communicating with it correctly. The normal status for the radio is Connected. Other possible status values are: Disconnected, Waiting for radio start-up, Waiting for authentication key, Waiting for connection reply, and Detected other USB device. Digital Radio Configuration Select Digital Radio on the menu to display the Digital Radio configuration page, as shown in Figure 3 (the Digital Radio tab is selected by default). Use this page to configure the capabilities of the DRG and how the digital-radio interface operates. Figure 3. Digital radio configuration page for common settings MotoTRBO DMR Donor Supplement 3
The settings on this page are common to all digital-radio interfaces, and are the same in both Basic and Advanced modes (see Common Digital Radio Settings on page 4). The settings applicable to the MotoTRBO DMR interface appear on the MotoTRBO Settings tab ( MotoTRBO Digital Radio Settings on page 7). Common Digital Radio Settings The settings on the Digital Radio page are common to all digital-radio interfaces. Omnitronics Gateway Interface Under Omnitronics Gateway Interface, configure the setting as follows: TCP Port Number is the port used by the DRG for incoming TCP connections the DRG acts as a TCP server and will accept incoming connections on this port from other Omnitronics devices. Digital Radio Settings The settings under Digital Radio Settings configure the digital-radio capabilities of the DRG, and determine what capabilities are published to Omnitronics Dispatch Consoles, such as Alto and RediTALK-Flex, and include the following: Disable Channel Change option allows you to disable the capability to change the channel on the radio (this capability will be preconfigured by software provided by the radio manufacturer). Disable Call Alert option disables the ability for the console operator to send an alert to another radio. A call alert allows the console operator to send an alert to another radio requesting that the radio operator call back the console operator (the radio operator acknowledges the alert by pressing PTT). Disable Individual Call option disables the ability to initiate an Individual Call from a console. Disable Individual Call Timeout option disables Individual Call timeouts. 4 Configuration
Individual Call Timeout is the time (in seconds) that the DRG will wait for individual-call activity before it cancels the Individual Call and reverts to default call mode. This timeout is only used when the Disable Individual Call Timeout option above is not selected. Disable Group Call option disables the ability to initiate a group call from a console to a group of radios. Disable Group Call Timeout option disables Group Call timeouts. Group Call Timeout is the time (in seconds) that the DRG will wait for activity before it cancels the group call and reverts to default call mode. This timeout is only used when the Disable Group Call Timeout option above is not selected. Disable All Call Timeout option disables All Call timeouts and allows the console operator to immediately set up a new call without the need to wait or cancel the All Call. If this option is not selected (i.e., the timeout is enabled), console operators will have to wait for the timeout before a new call setup is allowed. All Call Timeout is the time (in seconds) that the DRG will wait for activity to cease before it cancels the All Call and reverts to default call mode. This timeout is only used when the Disable All Call Timeout option above is not selected. Call Setup Timeout is the timeout applied to call setup when the console operator does not PTT within a reasonable time (see Figure 4 on page 7). The Alto console operator can send a request to set up a specific call type. If the operator presses PTT within the specified timeout, the DRG will set up this call type. However, if no PTT is received during this timeout, the DRG will revert to its default call state. If an incoming call is received during this timeout, the DRG will accept the incoming call and it will void the operator s original request. In this case, the operator will have to request the call type again after the incoming call is terminated. Disable Emergency option disables access to the Emergency feature from the DRG and any connected dispatch consoles such as Alto. Disable Text Messaging disables the ability to send a text message to a specific radio or to a group of radios. MotoTRBO DMR Donor Supplement 5
Default Call Type defines the type of call made by the DRG once it reverts to default call. The options available are: Radio determines call type, All Call, and Group Call (see Digital Radio Call on page 12). Defaults to All Call. Default Group determines the group to be called. Ranges from 1 to 1,000,000. Defaults to 1. Remote Radio Commands Each of the following options disables a specific remote radio command. This also affects the Diagnostics page: when you select an option, the corresponding command will not be available under the Remote Radio Commands section (see Remote Radio Commands on page 14). Disable Radio Check disables access to the Radio Check capability from the DRG and any connected dispatch consoles such as Alto. Disable Stun Radio disables access to the Stun Radio capability from the DRG and any connected dispatch consoles such as Alto. Disable Revive Radio disables access to the Revive Radio capability from the DRG and any connected dispatch consoles such as Alto. Disable Monitor Radio disables access to the Monitor Radio feature from the DRG and any connected dispatch consoles such as Alto. Call Timeouts Call timeouts are illustrated in the timing diagram depicted in Figure 4. The purpose of a call timeout is to ensure the connection is maintained during overs so that the call is not prematurely disconnected. If no further activity (BUSY/PTT) is detected during the time specified by the call timeout, the call will automatically disconnect. The timeouts for each call type (IND, GRP, ALL) can be configured independently, and can be enabled or disabled as required. Note The radio system uses similar call timeouts, and when determines that a call is completed due to a timeout, it will end the call and notify the DRG. It is advisable that you always set the DRG timeouts greater than the actual radio timeouts. 6 Configuration
If the timeout associated with a particular call is not disabled, the DRG will maintain the connection (call type and recipient) and reset the call timeout after each over. When a call timeout occurs (no one pressed PTT within the timeout), the DRG will revert to the default call type. If the timeout associated with a particular call is disabled, the DRG will apply the default call configuration (All Call) once PTT/BUSY clears. Figure 4. Digital radio timing diagram showing call timeouts MotoTRBO Digital Radio Settings Select the MotoTRBO Settings tab to display the settings applicable to the MotoTRBO interface, as shown in Figure 5. This page is the same in both Basic and Advanced modes. These settings are the same settings provided with the MotoTRBO Customer Programming Software (CPS), and are the only parameters required for Text Messaging purposes. MotoTRBO DMR Donor Supplement 7
Figure 5. Digital radio configuration page for MotoTRBO CAI Network is a value that is combined with the Radio ID to produce the individual radio's air interface network IP address (see MotoTRBO Customer Programming Software). CAI Group Network is a value that is combined with the Group ID to produce the group's air interface network IP address (see MotoTRBO Customer Programming Software). TMS UDP Port specifies a dedicated port number for the target destination (e.g. computer or radio) to support the text messaging service (see MotoTRBO Customer Programming Software). Using the USB Port The USB port of the DRG must be connected to the USB port of the MotoTRBO donor radio. Omnitronics cable OMC199 can be used for this purpose (see Connecting the DRG on page 21). For the DRG to communicate with a MotoTRBO donor radio, the USB port on the donor radio must be configured. Configuring a MotoTRBO radio to enable its USB port is performed using the MotoTRBO Customer Programming Software (CPS). The option to reprogram the USB port only appears in the CPS software when in Expert mode. For further information, please consult the Motorola user documentation supplied with your radio. 8 Configuration
Support for MotoTRBO Scan Mode MotoTRBO mobile radios can be configured to scan through a predefined set of channels; and if there is valid reception on a channel, the scan will lock onto that channel while there is traffic on it. The scan will wait a certain amount of time (typically 5 to 10 seconds) for subsequent traffic on it before it will resume the scanning. When a mobile donor radio in scan mode stops scanning because it locked on a talk group, the talk group number will be displayed on the RediTALK channel button. The DRG100-MotoTRBO can be configured to use the Radio Determines Call Type option for its Default Call Type setting. This will allow a RediTALK or Alto operator to talk back on that same channel by just pressing PTT; however, the operator needs to press PTT before the radio starts scanning again. If the Default Call Type setting is not configured for Radio Determines Call Type, the RediTALK PTT will not necessarily go to the channel on which the scan stopped. MotoTRBO DMR Donor Supplement 9
Diagnostics and Statistics This chapter discusses the diagnostic features of the DRG and how to use these features to troubleshoot and test the MotoTRBO DMR digitalradio interface. This chapter includes the following topics: Digital Radio Diagnostics Statistics on page 16 Digital Radio Diagnostics The DRG provides a separate diagnostics page for performing basic diagnostics and troubleshooting of the digital-radio interface. Select Digital Radio under Diagnostics to view the Digital Radio Diagnostics page, as shown in Figure 6. Some of the diagnostic sections shown on this page may not be visible depending on whether the corresponding capability is enabled on the Digital Radio configuration page (see Digital Radio Settings on page 4). For instance, if you select the Disable Text Messaging option to disable the Text Messaging capability, the Send Text Message section will not be visible. MotoTRBO DMR Donor Supplement 11
Figure 6. Diagnostics page for MotoTRBO interface Digital Radio Call The Digital Radio Call section allows you to perform several diagnostic tests associated with Call Setup and Busy Activation, as discussed below. Call Setup Use this section to set up and test a particular call type. Call Type selects the type of digital-radio call you want to make. The options available depend on whether the corresponding call-type option is enabled on the Digital Radio page (see Digital Radio Settings on page 4) and how the radio is configured, but may include the following: Default Call The next radio call will become the default type of call for this radio. 12 Diagnostics and Statistics
Individual Call Group Call All Call Call Alert Calls a single radio. Calls all radios in a particular group. Multiple calls to all radios on the network. Sends a call alert to one radio (sent immediately without waiting for the next Push To Talk request). Destination: Radio ID or Group ID is the identity of the radio or group of radios to which you want to send the message. To set up a particular call to a radio, or group of radios, select the call type from the Call Type dropdown, type the numerical destination into the Destination: Radio ID or Group ID text box, and then click Setup Call to send the request to the radio this may occur as soon as you click the button or it may occur on the first Push-to-Talk. Once the request is sent, the call type should appear next to Call Type under the Radio Status section (see Radio Status on page 15). Busy Activation Toggle Busy simulates and tests the busy signal on this DRG. This is useful when you suspect the busy signal from the repeater/basestation is not detected. To simulate and test the busy signal, click Activate Busy. This should send a busy indication to the dispatch console so you can check whether the busy signal operates as expected. You should also see the busy indication under Radio Status section (see Radio Status on page 15). Click the button again to terminate the test. Channel Change Use the Channel Change section to send a channel-change request to the radio. This section will only be visible when Channel Change capability is not disabled (see the Disable Channel Change option on page 4). Channel Number is the number of the channel on the radio to which you want to change. MotoTRBO DMR Donor Supplement 13
To send the channel-change request to the radio, type the channel number into the Channel Number text box, and then click Set Channel. This should change the channel on the radio to that specified by the Channel Number setting. Send Text Message Use the Send Text Message section to send a text message to the specified radio or group or radios. This section will only be visible when the Text Messaging capability is not disabled (see the Disable Text Messaging option on page 5). Message Type allows you to select the type of message to send and can be one of the following: Individual or Group. Destination Radio ID is the identity of the radio to which you want to send the message. To send a text message, select the type of message from the Message Type dropdown, type the numerical destination into the Destination: Radio ID or Group ID text box, type your message into the Example Text Message text box, and then click Send Text. Remote Radio Commands Use the Remote Radio Commands section to send remote radio commands to the remote radio. Note If you have disabled all of the remote radio commands on the Digital Radio page, this section will not be visible (see Remote Radio Commands on page 5). Command is the command you want to send to the radio and can be one of those listed below. The commands available will depend on the capabilities and configuration of the radio: Radio Check Sends a message to a particular radio ID to determine whether the radio is powered on and receiving. 14 Diagnostics and Statistics
Stun Radio Revive Radio Sends a message to a radio terminal to temporarily disable (stun) the radio. Sends a message to a radio terminal to enable (revive) the radio was previously stunned. Monitor Radio Sends a message to radio terminal and places the radio into monitor mode. Note Some of these commands may not be available depending on whether the corresponding capability is disabled on the Digital Radio page (see Remote Radio Commands on page 5). Destination Radio ID is the identity of the radio to which you want to send the command. To send a command to the radio, select the command from the Command dropdown list, type the numeric radio identity into the Destination: Radio ID text box, and then click Execute to send the command. Radio Status The Radio Status section displays the current status of the digital radio connected to the DRG. The information displayed depends on the radio functionality and firmware, and may include the following: Communication Status indicates the current communication state of the link between the DRG and the connected digital radio. It shows OK if the communication link is good or failed if the link is not working. Push To Talk indicates whether the radio is currently transmitting (ON) or not transmitting (OFF). Busy indicates whether the radio is currently receiving (ON) or not receiving (OFF). Call Type indicates the current active call type, which can be: All Call, Group Call, or Individual Call. MotoTRBO DMR Donor Supplement 15
Radio ID indicates the identity of the radio that is receiving or transmitting. Channel Number indicates the currently selected radio channel. Group ID indicates the currently active group (transmitting or receiving). Last Text Message Received shows the last text message received from a radio. Last Text Message Sent shows the last text message sent. Statistics Select Statistics under the Diagnostics menu to display the Statistics page, as shown Figure 7. The page is the same in both Basic and Advanced modes, and provides comprehensive statistics about the operation of the DRG. MOTOTRBO Statistics The MOTOTRBO Statistics section shows the information specific to the MotoTRBO interface. USB transmit bytes shows the count of bytes sent from the DRG USB port to the MotoTRBO radio. USB receive bytes show the count of bytes received from the MotoTRBO radio. USB transmit errors shows the number of times the DRG was unable to send a message to the MotoTRBO radio via the USB port. USB failed detection attempts shows the number of times the DRG was unable to perform the USB start-up sequence correctly. This error indicates that the USB is not working correctly or that the radio is powered down or disconnected. USB radio family shows the type of MotoTRBO radio connected to the USB port when communicating correctly. The possible values are: Mototrbo Core Portable Mototrbo Core Mobile Mototrbo Enhanced Portable with display 16 Diagnostics and Statistics

Viewing the Statistics page for MotoTRBO DMR interface Omnitronics RTP Statistics The Omnitronics RTP Statistics section shows the various statistical counters and other useful information for RTP and RTCP packets. RTP receive total packets is the total number of RTP packets received. MotoTRBO DMR Donor Supplement 17
RTP receive valid packets the number of valid RTP packets received from the remote device. RTP receive invalid packets is the number of packets received that do not contain valid RTP formatting. If this number is very large, it may indicate that this port is being used by some other network protocol. RTP receive valid bytes is the total number of bytes received via RTP. RTP receive sequence errors indicates the number of packets that either were not received or which arrived out of order. If this value is large, it indicates that the network is experiencing packet loss or excessive network jitter. RTP receive packets too late indicates that a packet containing audio arrived at the DRG after it should have been played. If this value is large, it indicates excessive and changing network propagation delays. RTP receive STUN packets indicates the number of value STUN messages received. Some VoIP clients send STUN messages on the RTP port to help determine network configuration. RTP receive MULTICAST packets shows the number of RTP packets received from a multicast address. RTP transmit packets is the number of complete network (UDP) VoIP packets sent, but does not include other packets such as web server data or SNMP packets. RTP transmit bytes is the total number of data bytes sent, and includes the payload data, but it does not include the overhead due to Ethernet protocol. Current transmit bytes per second is an estimate of the current bandwidth usage for VoIP. This will display a non-zero value only if the DRG is currently transmitting audio information. Time since valid RTP packet is the time in milliseconds since the last RTP packet was received. RTCP receive total packets is the total number of RTCP packets received. RTCP receive valid packets is the number of valid RTCP packets received from the remote device. RTCP receive invalid packets is the number of invalid RTCP packets received from the remote device. 18 Diagnostics and Statistics
RTCP receive valid bytes is the total number of bytes received via RTCP. RTCP transmit packets is the number of complete network (UDP) VoIP packets sent, but does not include other packets such as web server data or SNMP packets. RTCP transmit bytes is the total number of data bytes sent, and includes the payload data, but it does not include the overhead due to Ethernet protocol. Time since valid RTCP packet is the time in milliseconds since the last RTCP packet was received. Source Name is the name (IP address) of other IPR/VoIP devices communicating with this DRG, such as: IPE/Radio:3@192.168.20.11. Location is the location or name configured in the remote DRG device, such as DxAltus Radio Channel 1. Firmware Information identifies the firmware, and the version of the firmware, that this IPR device is running. Source IP Address is the source IP address for this audio source, such as 192.168.20.111. Source UDP Port is the UDP Port for this audio source, such as 5008. Received packets is the number of VoIP data packets received from the remote device. Duplicate packets is the number of packets that have been detected containing exactly the same data (network errors). Misordered packets is the number of packets that have arrived out of order, usually due to network delays. Packets arrived too late is the number of packets that have arrived after the point where they should have been played (network errors due to high latency). Current playout delay is how much audio (in milliseconds) the DRG device is currently holding in its jitter buffer. Current BUSY State is the current state of the Busy (Mute) input. Current PTT State is the current state of the remote audio source requested for the local DRG PTT output. This will appear if the remote site currently has an active busy signal from a connected radio. MotoTRBO DMR Donor Supplement 19
Interface Information This appendix discusses some important information about your DRG product, and includes the following topics: Connecting the DRG Known Issues Configuring the MotoTRBO Radio on page 23 Connecting the DRG The information in this section includes the interface connection requirements. You will need the following hardware to connect the DRG: Omnitronics interface cable OMC199 (see Figure 8 on the following page) Suitable DC power supply for DRG100: 12VDC @300mA (min) Ethernet connection Known Issues At the time of publication, the MotoTRBO firmware does not support text messages from a terminal radio to the DRG. Outbound text messages, however, are supported. Due to a limitation in the MotoTRBO XCMP protocol, it is not possible for a radio to send a message to a DRG. However, it is possible for a radio to reply to a text message. MotoTRBO DMR Donor Supplement 21
Figure 8. Interface cable OMC199 22 Interface Information
Configuring the MotoTRBO Radio The accessory port on a MotoTRBO radio is used for USB communication with the DRG. This port can be configured for either PC and Audio or Data Only. When interfacing the radio to a DRG, it is important that the accessory port is configured for Data Only. If the DRG reports that the USB interface is initialized and connected to the radio, but the radio does not communicate with the DRG, the accessory port is most likely configured for PC and Audio instead of Data Only. You can confirm whether this is the case by viewing the MotoTRBO Status page (see Digital Radio: MotoTRBO Status on page 2). At the bottom of this page under the section Digital Radio: MOTOTRBO Status, you will see the status of the USB connection and the radio. If the DRG cannot communicate with the radio, you will see the information similar to that shown in Figure 9. This information will also appear in the Diagnostics report. Figure 9. MotoTRBO status information Additionally, the channel button on the console (RediTALK or Alto) will indicate a failure state (diagonal lines). In some cases, we have found that the default configuration for the accessory port, as configured by the manufacturer, is PC and Audio. The DRG uses the radio s USB interface for data communication only. Hence, you must ensure the radio s accessory port used for USB communication is configured for Data Only.
