RS-232 Communication Interface
211
DCD (Data Carrier Detect) - this is an input signal from the DCE that
indicates a carrier signal is being received and that presumably data is to be
received for forwarding to the DTE connected.
Wiring Connectors for
RS-232 Communication
To connect Allen-Bradley devices with other devices over RS-232, you must
wire the cable connectors so that communication can occur through the
cabling, which provide the interface between devices.
Types of RS-232 Connectors
The figures below show male connectors, and their pinout locations, for
Allen-Bradley devices.
DTE Pinout
Channel 0 is configured as DTE for all SLC 5/03, SLC 5/04, and SLC 5/05
processors. The pinouts are the same as the 9-pin personal computer port.
