WIRING THE MODBUS CARD

For four-wire networks. All four RS-485 network signals including TxD(+), RxD(+), TxD(–), and RxD(–) must be connected to the terminal strip as illustrated in Table 1. Verify that the Modbus Card J9 and J10 jumpers are set to the four-wire option (see “Four-Wire Communication” on page 4).

RS-485 Modbus Port

For two-wire networks. Connect the RS-485 network signal TxD(+) to the Modbus RxD(+) input signal (DB-9 Pin 1). Connect the RS-485 network signal TxD(–) to the Modbus RxD(–) input signal (DB-9 Pin 6). The Modbus Card factory-default jumper setting for J9 and J10 is two-wire communication.

For four-wire networks. All four RS-485 network signals including TxD(+), RxD(+), TxD(–), and RxD(–) must be connected to the pin assignments on the DB-9 connector as illustrated in Table 2. Verify that the Modbus Card J9 and J10 jumpers are set to the four-wire option (see “Four-Wire Communication” on page 4).
