5 1. Installing CADET and KGCT Applications If you whish to change the SKIM behaviour, the first step is to download CADET and KGCT applications. Both applications are available on the following web site: You need to get a user account and request for the profile KA Generic Product. Please note that the software requires at least Windows XP and one of the following USB to CAN interface: IXXAT interface Kvaser interface NEXIQ interface (USB-Link only) ifak system interface You will need to install the CAN interface drivers from the manufacturer website or the CD. Be aware that the drivers may not be compatible with your operating system. page 2

6 2. Understanding KGCT Functionality Because KGCT software is a plugin of CADET software, CADET must be started prior to access SKIM gateway. Then, you have to click on Read "button" or double-click on "CCP Node" in order to read the SKIM internal information datas: page 3

7 2.1 CADET "Module ID" tab Once the SKIM gateway is read, module information datas are displayed in read only mode. For this reason, no changes could be done here on datas. Note that customer parameters section could be modify to fit your needs. But to be able to do such operations, SKIM module must be place in bootloader mode (see below). 2.2 CADET "Commands" tab The following actions could be done (4 buttons available): Program a configuration (by loading a configuration file from disk and saving it into the SKIM memory). Get the internal configuration and start automatically KGCT application. Launch KGCT application (without getting internal SKIM configuration). Start bootloader mode. SKIM must be read again. In bootloader mode, customer parameters and firmware could be updated. 2.3 CADET firmware update When in bootloader mode, SKIM application firmware can be updated by clicking the Firmware button and following the information on screen. Note that firmware update could only be done from CADET. page 4

8 3. KGCT Application Basically, KGCT is used to create, edit, save (on disk) or write (in SKIM) different configurations for general I/O pins. Each I/O pin could be configured individually as an input or an output to do one of the following functions: PWM Output Mode Ohm Meter Mode Frequency Meter Mode Volt Meter Mode Ampere Meter Mode Pulse counter Mode Square Wave Output Mode Switch Input Mode Low Side Output Mode The next sections will describe how to configure the I/O pins for each of the functions listed above. page 5

9 3.1 PWM Output Mode In this mode, the I/O is configured as PWM output generator like the following: Used to set the frequency output. Frequency range is from Hz to 25 khz. Used to enable or disablethe internal 6.8 kω pullup resistor. Used to set the PWM output polarity: Ex.: PWM = 25% with active pulse HIGH Ex.: PWM = 25% with active pulse LOW Used to set the initial output duty cyle. Also used as limp home value when no J1939 messages detected. Also used as limp home value when no J1939 messages detected. Duty cycle range is from 0% to 100% When "Enable" is checked, output duty cycle value is read directly from the CAN bus. Used to select PGN number, data index (from which byte data will be retrieved) and data size (expressed in byte). page 6

10 3.1 PWM Output Mode - continued Used to scale the incoming data. If fields are left empty, up to unsigned 32-bits input data is taken as is (%). Otherwise, linear interpolation is done according to the programmed fields to obtain duty cycle value from J1939 network. Once the configuration is completed: you can save it on disk with "Save" button you can write it into SKIM with "Write" button. * The way to save configurations is the same for all I/0 functions. page 7

11 3.2 Ohm Meter Mode In this mode, the I/O is configured as ohm meter input like the following: Resistor input range is from 0 to 400 Ω. This is a fixed range. Used to scale the outgoing data. If fields are left empty, up to unsigned 32-bits output data is taken as is (ohms). Otherwise, linear interpolation is done according to the programmed fields to obtain J1939 value (to be broadcasted) from resistor input value. Used to select the PGN number, priority and destination address. Used to select data index (from which byte data will be sent), data size (expressed in byte) and the desired message transmission rate. Note that 2 different messages could be send in this mode. page 8

12 3.3 Frequency Meter Mode In this mode, the I/O is configured as frequency meter input like the following: Used to select on which edge the SKIM will trig. Frequency input range is from 1 to 2500 Hz. Used to scale the outgoing data. If fields are left empty, up to unsigned 32-bits output data is taken as is (Hz).

Used to select the PGN number, priority and destination address. Used to Select data index (from which byte data will be sent), data size (expressed in byte) and the desired message transmission rate. Note that 2 different message could be send in this mode.!!! WARNING!!! If the input rate frequency reaches the maximum limit of 2500Hz for more then 10 consecutives cycles, the I/O is permanently disabled and reading will be set to zero after timeout time of 2s. Only power up reset restore I/O functionality. page 9

13 3.4 Volt Meter Mode In this mode, the I/O is configured as volt meter input like the following: Voltage input range could be: 0-12VDC or 0-32VDC. Used to scale the outgoing data. If fields are left empty, up to unsigned 32-bits output data is taken as is (V). Otherwise, linear interpolation is done according to the programmed fields to obtain J1939 value (to be broadcasted) from voltage input value. Used to select the PGN number, priority and destination address. Used to select data index (from which byte data will be sent), data size (expressed in byte) and the desired message transmission rate. Note that 2 different message could be send in this mode. page 10

14 3.5 Ampere Meter Mode In this mode, the I/O is configured as ampere meter input like the following: Used to scale the outgoing data. If fields are left empty, up to unsigned 32-bits output data is taken as is (A). Otherwise, linear interpolation is done according to the programmed fields to obtain J1939 value (to be broadcasted) from current input value. Current input range is from 0 to 25mA. This is a fixed range. Used to select the PGN number, priority and destination address. Used to select data index (from which byte data will be sent), data size (expressed in byte) and the desired message transmission rate. Note that 2 different message could be send in this mode.!!! WARNING!!! If the input current reaches the maximum limit of 25mA, the I/O is temporary disconnected to protect internal shunt resistor. When pin voltage falls under 5V, the I/O will be reconnected. page 11

15 3.6 Pulse Counter Mode In this mode, the I/O is configured as pulse counter input like the following: Used to select on which edge the SKIM will trig for pulse counting. Frequency input range is from 1 to 2500 Hz. The total pulse counter will be transmitted on J1939 network. Used to select the PGN number, priority and destination address. Used to select data index (from which byte data will be sent), data size (expressed in byte) and the desired message transmission rate. Note that 2 different message could be send in this mode.!!! WARNING!!! If the input rate frequency reaches the maximum limit of 2500Hz for more then 10 consecutives cycles, the I/O is permanently disabled and reading will freeze to last count value. Only power up reset restore I/O functionality. page 12

16 3.7 Square Wave Output Mode In this mode, the I/O is configured as square wave output generator like the following: Used to set the frequency output. Frequency range is from Hz to 25 khz.

Used to select the PGN number, priority and destination address. Used to select data index (from which byte data will be sent), data bits (on which bits switch value state will be transmitted) and the desired message transmission rate. Note that 2 different message could be send in this mode. page 14

18 3.9 Low Side Output Mode In this mode, the I/O is configured as low side output like the following: Used to enable or disable the internal 6.8 kω pullup resistor. Used to determine the output state (ON/OFF) when J1939 "Enable" is not checked. Also used as limp home value when no J1939 messages detected. When activated, output always gives a GND signal level. Used to determine the activation logic when J1939 "Enable" is checked. When DIRECT logic is seleted, output will be activated when incoming data is "1". When INVERSE logic is seleted, output will be activated when incoming data is "0". When activated, output always gives a GND signal level. page 15

19 3.9 Low Side Output Mode - continued Used to select the PGN number for incoming data. Used to select data index (within which byte data will be received) and data mask bits (from which bits activation data will be read). page 16

20 4. SKIM Frequency Output Limitation Because of the SKIM hardware, there are some limitations when using "frequency functions". Those limitations are only related to the SKIM 8 I/O. The same frequency should be used for I/O 1 and 3 (all connected to the same TPM2 internal timer). The same frequency should be used for I/O 2, 4, 5, 6, 7 and 8 (all connected to the same TPM1 internal timer). For a specific timer, if the frequencies defined for its related I/0 are not the same, then the frequency defined for the first I/O connected on the timer will be used. Example: I/O 2, 5 and 6 are configured as frequency functions using 3 different frequencies. The SKIM will use the frequency defined for I/O 2 for all other inputs / outputs. And in this case, resuting values for I/O 5 and 6 will be incoherent. page 17

21 5. SKIM Limp Home Mode The PWM Output Mode is related to an incoming J1939 message. If the SKIM loses the CAN network or the associated output message before timeout event, the output value will be set to the limp home value. In this particular case, the "Initial Duty Cycle" field is used as limp home value. The Low Side Output Mode is related to an incoming J1939 message. If the SKIM loses the CAN network or the associated output message before timeout event, the output value will be set to the limp home value. In this particular case, the "Initial Output State" field is used as limp home value. Each I/O output have his own limp home mode. The timeout period is set to time of 20s. page 18

22 6. Typical J1939 Signal Ranges This section defines the range of values that will be used in scaling functions for incoming and outgoing parameters on J1939 CAN network. 6.1 Transmitted / Received Signal Range name 1 byte 2 bytes 4 bytes Valid signal 0x00 to 0xFA 0x0000 to 0xFAFF 0x to 0xFAFFFFFF Error indicator 0xFE 0xFExx 0xFExxxxxx Not available / Not requested 0xFF 0xFFxx 0xFFxxxxxx 6.2 Transmitted Discrete Values Range Name Transmitted Bits Disabled (off) 00 Enabled (on) 01 Error indicator 10 Not available / Not installed Received Discrete Control Commands Range Name Received Bits Disable command (turn off) 00 Enable command (turn on) 01 Reserved 10 Don t care / No action 11 page 19
