Rs-422/485 Connector - adept technology SmartController EX User Manual

These ports support the RTS, and CTS signals used for hardware handshaking (also known as
modem control). By default, these signals are not enabled. To configure hardware handshaking
and other communication parameters, use the Adept ACE software. The eV+ designations for
these ports, when referenced in the eV+ ATTACH or FSET instructions, are shown in the fol-
lowing table.
NOTE: To configure the port speed and other communications parameters, use Adept ACE soft-
ware.

RS-422/485 Connector

The RS-422/485 connector is a 9-pin DB9 male connector. The pin assignments are shown in
