Connecting the MESR9x2D-x

The MESR9x2D-xhas two serial connections that support RS-232, RS-422 and RS-485 (2- and 4-wire). The unit has two connectors, both of which are DB-9M connectors. You must connect the Modbus network to the Modbus gateway via a serial cable. The MESR902D is a DTE. If the Modbus network is a DTE, use a null modem (cross-over) cable. If the Modbus network is a DCE, use a straight-through cable.
