X2: Potential-free RS232 serial interface
X3: Triggering of "Remote signalling"
X4: A remote panel can be connected to this potential-free CAN
interface.
X5: Potential-free RS485/RS232 serial interface internally wired
to X91
Configuration jumpers:
J1: 1-2: Firmware update; 2-3: (default)
J4: All closed: RS485 (default)
J5: All closed: RS232
The transmission topology of the Modbus interface (connector X5)
is set by means of the two configuration jumper blocks (J4/J5). The
factory setting is RS485.
In order to be able to use the Modbus interface as a point-to-point
connection via RS232, you must remove all jumpers from block J4
and plug them in on block J5.
