4 SECTION 1 - Description The Translator feature changes the basic function of the C25 series decoders. The C25 Translator converts an ANI burst in P25, or FleetSync (referred to as Incoming ANI ) into MDC-1200 so that the signal can be decoded at a dispatch console capable of only MDC-1200 signaling. The Translator operates in parallel with the Audio In of the console. The parallel configuration means that the console will see Incoming ANI and the translated MDC-1200 data bursts. The translator does not stop the Incoming ANI bursts from reaching the console. The Translator does not mute the incoming data burst. Since the console is not compatible with the incoming ANI burst, the burst will be ignored. Depending on the console, the incoming data bursts may or may not be heard by the dispatcher. Voice audio will pass directly to the console. Voice audio does not pass through Translator. Voice audio is not muted or affected in any way by the Translator. The Dispatch console will hear 2 data bursts. The 1st will be the Incoming ANI data, the 2 nd will be the MDC-1200 burst. The processing time of the Translator creates a delay between the data bursts that prevents any overlap of the 2 data bursts. Page 4

5 Operation Example: An APCO P25 radio in the field keys up and his ID is transmitted within the P25 digital burst. At the C25 Translator, the P25 digital burst is decoded. The decoded ID formatted into an MDC-1200 compatible data burst. The data burst is injected into the audio path approximately 10mS after the original P25 data burst was received. Since the P25 data burst is not recognized by the dispatch console it is ignored. Approximately 10mS later the console will see the MDC-1200 burst which the console will decode and display. Notes: Can be implemented with a C25 I, C25 II, C25 III, or MCI. C25 Translator takes in P25, or FleetSync and always outputs MDC APCO P25 ID range is $ to $FFFFFF. However the MDC-1200 ID range is $0000 to $FFFF. Therefore if the decoded P25 ID contains 5 or 6 characters, the most significant characters will be ignored. Examples: Decoded APCO P25 Translated to MDC- Comment ID 1200 ID $F123BA $23BA Characters F, 1 are ignored $123BA $23BA Character 1 is ignored $23BA $23BA $3BA $3BA Where: $ means number in hexadecimal. Alias option not available with the Translate option. No Acknowledgements, no sounder, no contact closures. No special reactions to Emergencies (no acknowledgements) FleetSync s 3 digit Fleet ID will be ignored. Not compatible with FleetSync II. Page 5

10 SECTION 5 Data Input details Data input is the signal input to the C25. This is discriminator audio from the radio. Data In + is the high side and Data In - is the low side. Data input is jumper selectable for high impedance single ended, high impedance balanced and 600 ohm balanced. In nonbalanced configurations, Data In - is referenced to ground. However, note that it is not directly shorted to ground. In balanced systems, it is signal return. Always attach an independent station ground to the rear panel P3 pin 8 or P2 pin 10. The input is capacitor coupled for DC blocking and is MOV protected. When interfacing to a radio, connection should be discriminator audio, before de-emphasis (flat audio). Data input + should be jumped for high impedance and data input should be jumped to ground. If connected to a balanced line, remove ground jumper JP-7. Data input is AGC conditioned so generally, no adjustment is necessary. A test point is provided for oscilloscope connection. If the signal is clipped and distorted, a potentiometer and a bank of gain jumpers can reduce gain. Alternately, if the signal is too weak, gain can be increased. Attenuation jumpers are described below. Use only one jumper at a time. Input Signal Attenuation Unbalanced Balanced 18 db JP-13 JP db JP-12 JP-9 6 db JP-11 JP-8 Page 10

11 JP5 provides an amplification stage to increase the data input signal. Amplification factors are described below. Observed Maximum signal at TP10 Gives this amplification to input 0.05 VPP 36 db 0.2 VPP 24 db 0.65 VPP 12 db 1.6 VPP 0 db If you experience a decode rate of less than 100%, view the ANI signal waveform at TP10. Adjust the attenuation jumpers so that the waveform is not clipped. Do not exceed the absolute maximum peak to peak signal level listed in the above table. Then view the waveform at TP-7 and adjust jumper JP-5 and R3 for a 1 Vpp ANI signal. Page 11

12 SECTION 6 Data Output details Data output is the translated ANI burst out of the C25. Data output is jumper selectable for single ended or balanced configurations. In Single Ended configurations, Data Out - is referenced to ground. However, note that it is not directly shorted to ground. In balanced systems, it is signal return. Always attach an independent station ground to the rear panel P3 pin 8 or P2 pin 10. The output is capacitor coupled for DC blocking, is MOV protected and is completely isolated by relays when not actively encoding. If connected to a balanced line, remove ground jumper JP-25. For 600 ohm operation, add jumpers JP-24 and JP-27. Data output must be adjusted to ensure that the target console sees a level about the same as the un-translated burst. Rear panel potentiometer R5 is available to adjust the level. The Self-Test command $$KEYT is used for setting outbound data deviation. This command forces a 10 second burst of data from the C25. Page 12

13 SECTION 7 Programming The C25 is set-up via the RJ-11 RS-232 serial connection. The RJ- 11 serial connection can be used with any computer running terminal emulation software like Hyperterminal. When Using Hypertermal, characters you type will not be visible on the computer display. Upon initial power-up, the C25 counts down for 10 seconds. After the countdown, the C25 is ready. To program the C25, type: $$C25 The C25 display will show the word: When in program mode, the C25 suspends normal operation until program mode is exited. The following menu will appear on HyperTerminal: Page 13

18 C25 II -Translator The C25 II is a single window dispatch display unit. The display consists of eight large 5x7-pixel LED display matrixes. This display will show the ID before translation to MDC Signaling Typical Translation Comments type Display APCO P Translated ID will be in hex, up to 4 characters. FleetSync A PTT ID has been received from radio whose fleet number is 123 and ID is The C25 II will show the pre-translated P25 ID. The display will not show the translated MDC-1200 ID. The C25 has two push buttons on the front panel. The right button is labeled CLEAR and clears the display. If a critical message was last received, pressing the button once clears the alert and pressing the button the second time clears the display. Critical messages are defined as any message that has been programmed to sound one of five different tone alerts. Clearing the alert stops the tone from sounding and also stops the display from alternately flashing ID and message type. Page 18

19 The left button is labeled REVIEW and when pressed, steps the display through the last 20 received messages. Messages are displayed just as they were received except the left most display shows the order in which the messages were received. The most recent message will be labeled a. Subsequent messages will be labeled b, c and so forth. To facilitate speedy review, non-ptt messages alternate in 1-second intervals between ID/alias and message type instead of 2-second intervals. To clear the review buffer, press and hold the review button while pressing the clear button. The review memory will be erased. The review buffer resides in SRAM and as such is volatile. If power is lost or removed, the review buffer will be erased. Page 19

20 C25 III -Translator The C25 III is a multiple window display unit. The C25 III will show the pre-translated P25 ID. The display will not show the translated MDC ID. The main display and its features are the same as the C25 II. Below the main display, there is a row which is capable of displaying up to 6 of the last ID s that were translated. Alarms and Alerts, Critical Message Designation These functions are not normally used in the Translator product. Please contact the Cimarron Technologies engineering Department to discuss Alarm functions for your system. Page 20

21 SECTION 9 Serial Port Note: The serial port is mainly for programming. However, the port will output the decoded ID slated for translation. Please contact the Cimarron Technologies Engineering Department if you plan to make extensive use of the Serial Port in your system. On the back of the C Plus, there is an RJ-11 six conductor phone jack. This port can be programmed as a printer port and be connected directly to a serial printer to record channel activity. Baud rates available are 1200, 2400, 4800, 9600 and with 7 or 8 data bits and odd, even or no parity. The C25 can be connected directly to a serial printer. The Cimarron Standard serial output format is the default format which contains time and date information. The RS-232 port can also be used to connect to the serial port of a computer for troubleshooting. The RJ-11 (6 pin modular) connector is RS-232 protocol compatible with pin assignments as described in the figure below: connection directly into a computer serial port connection directly to a serial printer RJ-11 Pin # DB-9F Pin # RJ-11 Pin # DB-9M Pin # 1 (Wht) Not Connected 1 (Wht) Not Connected 2 (Blk) 8 2 (Blk) 8 3 (Red) 7 3 (Red) 7 4 (Grn) 2 4 (Grn) 2 5 (Yel) 3 5 (Yel) 3 6 (Blu) 5 6 (Blu) 5 Page 21

22 SECTION 10 Troubleshooting Performing Self Tests To facilitate troubleshooting of the C25, the following special commands exist. Commands $$LOOP $$KEYT $$OUTS Definition Generates a PTT ANI message and then an emergency message in the signaling format currently in operation. Repeats for 16 seconds, one message per second. Keys the C Plus and sends data for 10 seconds in the signaling format currently in operation Causes the outputs to individually wiggle for 3 seconds each. Affects Key, RXMute, TXCtl, Out1 and Out 2. $$DISPLAY Illuminates all pixels in the display (C25/C Plus II and III) The Local Loop-Back test ($$LOOP) generates a PTT ANI message and then an Emergency ANI message in the data format selected previously (GE Star, MDC-1200, FleetSync ). This signal generation will continue for 16 seconds, with one message being generated per second. Emergency acknowledgments are not sent during this test. If the test is successful, the display will display the decoded messages. If an alias has been programmed for the test ID, then the alias will be displayed. Test ID s are as follows: Data Format Test ID GE Star 8888 MDC FleetSync DTMF Not Supported To prepare for the local loop-back test, disconnect the C25 from the attached communications system and connect Data Out A to Data In A and connect Data out B to Data In B. The Data Modulation Test ($$KEYT) is used to adjust data output for the proper deviation level. When selected, the C25 will activate the Key line and send 10 seconds of pseudo-data in the data format selected previously. Output level should be adjusted so that data deviation is equal to or just below voice deviation. The Output Line Test ($$OUTS) wiggles output lines to allow verification of operation. (Key, RXMute, TXCtl, Out 1, Out 2). This test should only be performed when the C Plus is not connected to an associated radio. Each of the above mentioned lines will be brought active for 500ms and then inactive for 500ms and then active for another 500ms. This cycle will continue for three seconds for each line. Only one line is wiggled at a time. Page 22

23 Installation Hints The C25 is AGC controlled and generally requires no adjustments to the receive signal. However, if you are having a decode rate of under 100%, try performing the following steps. Refer to the main board schematic. Notice that there are attenuation networks controlled by JP13, JP12 and JP11 (for unbalanced systems) and JP10, JP9 and JP8 (for balanced systems). Also notice that after the attenuation networks, there is an amplifier (U9B) whose gain is controlled by jumper placement on JP5. Use an oscilloscope to view the ANI signal waveform at TP10. Adjust the appropriate jumpers in the attenuation circuitry so that your waveform is not clipped and maximum values are not exceeded. See Section 6 for details. Now view the waveform at TP7 and adjust jumper JP5 and VR3 for a 500mV p/p ANI signal. The C25 will be injecting audio into the radio. It is very important to adjust data out using VR5 to ensure the correct deviation level. The deviation level should be just marginally below that of voice. Keep in mind that most transmitters have limiter circuitry. This circuit ensures that the radio will never over-deviate and violate FCC rules. The limiter does this by clipping the transmit audio. The output of the C25 must be adjusted to a point just below where limiter clipping occurs. If the limiter is allowed to function, the C25 data will be distorted. Page 23
