So we are using the RS232 Bridge built in to the Black jags to drive our CAN Bus but we have run in to some problems. I will attempt to Document the issue as clearly and as accurately as I can.
Documents used in the configuration and setup of our CAN Bus( for reference)
Changes we have made from the above Documentation ( all related to changes documented in the 2014 Manual)
- All references to Firmware other than 107 for Black Jaguars(MDL-BDC24) and Firmware 101 for the "gray" Jaguars(MDL-BDC) have been installed as Version 107 for Black Jaguares and 101 for "gray" Jaguars.
- All references to cRio Firmware other than FRC_2014_v52 are installed as FRC_2014_v52.
- All references to the TI BDC-COMM tool other than version 107 are installed as version 107 (From VexPRO).
OK so here is what we have done
- We have created 3 Rs232 DB9 to RJ12 connectors ensuring that we have placed a 100ohm resistor between the red and green wires as described in the "You Can do CAN" Document.
- We have created 3 CAN Terminators with a 100ohm resistor between pins 2 and 3 as described in the "You Can do CAN" Document.
- We have verified with a multimeter that all the connections are correct and all the resistances are on the correct pins for all terminators and connectors
- We have purchased pre made 4c4p CAN Cables( Several 6" and a few 12") from AndyMark/CrossTheRoad.
- We have purchased a premade 6c6c reversed cable (7') from DigiKey as given in the "CAN Getting started" document.
- We have installed the 107 BDC-Comm software on our Windows 7 Laptop.
- We have Installed a the USB to Serial Software that came with our USB to Serial Cable.
- We have updated all our Black Jags to the latest 107 Firmware using the latest BDC-COMM tool with only 1 Jaguar attached. (Jaguar Firmware Update Instructions).
- We have assigned all our Black Jags individual odd numbers with only 1 Jaguar attached.(Jaguar Firmware Update Instructions).
Here is where our problems start
When we attempted to update the Gray Jags with the latest firmware our BDC Comms was unable to see more than 1 Jag. for any Setup ( B1-G1, B1-G2, B1-B2, B2-B1, B2-G1, B2-G2) all the following would show ONLY the First Black Jag in the series, the second jaguar (of either colour, even ones we have verified to talk when hooked up as the first Jag) would blink yellow.
Troubleshooting- We verified the cables were in the correct order and correct Ports ( Getting Started Guide).
- We have verified the cables were correct to what was documented
- We have verified that the Firmware is correct by re updating to 107
- We have changed the assigned IDs of the Black Jags when connected to the Gray Jags.
- We have Reset the Black and Grey Jags with the Reset Buttons.
- We have changed out the terminators used and the connectors used.
- We have verified that we are plugging in the 6c6p connector into the IOIOI port on the Black Jag and the Andymark/CrossTheRoad cable is plugged in to the other port and the first port on the Gray Jag.
- We have verified that the battery is fully charged and the connections are solid ( working Jag is solid Yellow all other Jags are flashing yellow).
Given this information what are we doing wrong?
