MVI69-GSC ♦ CompactLogix or MicroLogix Platform
Generic ASCII Serial Communication Module
RS-232: Null Modem Connection (No Hardware Handshaking)
This type of connection can be used to connect the module to a computer or field device
communication port.
Note: For most null modem connections where hardware handshaking is not required, the Use CTS Line
parameter should be set to N and no jumper will be required between Pins 7 (RTS) and 8 (CTS) on the
connector. If the port is configured with the Use CTS Line set to Y, then a jumper is required between the
RTS and the CTS lines on the port connection.
