CAN Termination Resistor
This section requires a bit of abstract thinking. If you’ve got this far you should be okey!
Suppose we call the ECU; Master,
and devices that send/receive data to/from the ECU we will call; Slave Eg:
Spartan 3 CAN, Digital dashboard, EGT controller, etc…
In most applications there is one Master (ECU) and then one or more Slaves that all share the same CAN Bus.
If “Spartan 3 CAN” is the only Slave on the CAN Bus, then the CAN Termination Resistor on the Spartan should
-be enabled using the
serial command “SETCANR1” By default the CAN Termination Resistor on the Spartan is enabled.
If There are multiple Slaves, then the Slave that is farthest from the Master (based on wire length) should have the CAN Termination
Resistor enabled, all other Slaves should have their CAN Termination Resistor disabled/disconnected.
In practice; it often doesn’t matter if the CAN Termination Resistors are properly set, but for the best reliability the CAN
Termination
Resistors should be properly set at this time.
Bootloader Mode - Required For Firmware upgrades
When “Spartan 3 CAN” is powered up without the LSU (Wideband) Heater Ground connected, it will enter bootloader mode.
Powering up the Spartan with the Heater Ground connected will not trigger the bootloader and Spartan 3 CAN will work as normal.
When Spartan 3 is in Bootloader mode there is an onboard LED, which can be observed through the case slits, that will shine a solid
green.
When in bootloader mode, serial commands are not possible. In Bootloader mode, only firmware update is possible,
all other functions are disabled.
To enter bootloader mode for a firmware upgrade:
1.
Make sure Spartan 3 is off, no power to Pin 1 or Pin 3 of the screw terminal
2.
Disconnect the sensor
3.
Disconnect LSU Heater Ground from Pin 4 of the screw terminal
4.
Power on Spartan 3,
5.
Check if the onboard LED is shining a solid green, if it is then your Spartan 3 is in bootloader mode
