RS485 T / CAN T
Enables/disables the on-board 120 Ω line termination resistors according to the standards; RS485
and CAN bus communication require a proper line termination value (
120 Ω assuming a CAT5
twisted pair cable is used
) resistors in both ends of the bus. If the M2M Control CX530 device is used
as an endpoint, the relevant jumper can be installed.
CAN WE
Connecting the CX530 to a CAN network can be dangerous. If the CX530 is not configured with
the correct network parameters, it can lead to network corruption and may interfere with other
connected equipment on the bus. Especially in vehicles, precautions must be taken in order to
prevent interruption of communication.
By default, reading from the CAN bus is enabled, and writing to the CAN bus is disabled. To
enable the CAN bus write capability, the CAN WE jumper must be installed.
Installing this jumper, thereby enabling the unit's CAN-bus writing capability, is done on the user's sole
responsibility. Infranet Technologies GmbH cannot be held responsible for any problems, or damage due to
the decision to enable the CAN-bus writing capability

These jumpers are used to select between current and voltage input measurement. With a jumper
installed on the relevant analog input, it will measure current between 0-20mA
