Notes on termination of older BlueConnect Modules
Older modules have no slide switches on the board.
With older BlueConnect Senor and Bus Modules, the termination of CAN bus and
Modbus is done via the configuration program Modbus Tool.exe.
see
4.7 Configuring Older Bus Modules
Older modules are not terminated at the factory.
If there is no possibility to terminate the CAN bus via the configuration program:
CAN bus termination by means of a resistor of approx. 120 Ω on the open terminals
for CAN-H and CAN-L on slot X4. Modbus termination by means of a resistor of
approx. 120 Ω on the open terminals for TX/RX+ and TX/RX- on slot X3.
