Publication 1799-IN012B-EN-P - July 2008

DeviceNet Wiring

DeviceNet wiring connections are made to the plug-in connector. The connector

plugs into connector J1 on the circuit board.

Serial Port DB9 Wiring

The module operates as an RS-232 or RS-485 device, depending on how the serial

communication lines are attached. For information about serial port connections,

see the DB9 9-Pin Connector Signal Assignments table and description. All signal

lines are isolated.

Serial Port Connection

The ASCII devices are connected to the 1799-DASCII module by using a three-wire

(or five-wire for RS232 hardware handshaking) communication cable.
