Configuring Serial Ports

The Adept SmartController EX motion controller has four serial I/O ports:

RS-232/Term

RS-422/485

RS-232-1

RS-232-2

See Connectors and Indicators on page 27 for the connector locations.

To configure a serial port, use the eV+ FSET program instruction, for example:

FSET (lun.num) "/BYTE_LENGTH 8 /STOP_BITS 1 /FLOW XON_XOFF /PARITY

NONE /SPEED 57600"

Refer to the eV+ Language User's Guide for more information on FSET. This applies to all of the

Adept SmartController EX motion controller's serial ports.

RS-232 Connectors

All three types of RS-232 connectors are 9-pin DB9 male (standard PC) connectors. The user-

supplied cable to connect to the RS-232 connectors should be a DB9, F/F, null-modem data-

transfer cable. The pin assignments are the same for all three connectors and are shown in the

following table.
