UIM2842
Standalone Operation
When working standalone, user can use the wiring scheme shown in figure 0-3.
Please note that, this wiring scheme should be used for setting the ID of a UIM2842
controller.
For long distance transfer, both ends of the CAN bus should be terminated with120Ω
terminating resistors. As UIM2501 converter has a build-in terminating resistor, user only
needs to attach a resistor at the other end of the bus. Please refer to the UIM2501 user
manual for how to enable the UIM2501 converter’s terminating resistor. CANH and CANL
should use a twisted wire pair.

Warning:Hot plugging is forbidden.
Warning: All controllers, gateways and subscriber equipments must be common-
grounded.
Except supply voltage port and
motor terminal, voltage on port
must be kept between -0.3~5.3V.
