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.
