Note!
The Hot Sync CAN Bridge card has build-in termination resistor enabled by jumper
J7. The default jumper setting without termination resistor is J7: Pin 2-3. Place the the
jumper J7 to correct setting: the first and last UPS modules should have the CAN bus
termination resistor enabled (Jumper J7: Pin 1-3).
In addition to the CAB bus cable a back-up pull-chain cable is needed for bypass operation.
