Modbus Configuration

Figure 13 MultiCom CCC interface as a Modbus interface (top view)

Connections:

X1: Internal inverter bus and power supply

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.
