Serial I/O Connections, 040 Module
Adept MV Controller User’s Guide, Rev C 75
CAUTION: The RS-422 and RS-232 ports on the 040 both use 25-pin
female connectors. Be sure to label each connector and take precautions to
avoid connecting to the wrong port.
a
Pins 4, 5 and 8 are used for “hardware handshake”, also known as “modem
control”. By default, they are disabled. To enable them, use the
CONFIG_C
utility program, the V
+
FSET
program instruction, or the
FSET
monitor
command. In some applications you can omit some or all of these lines;
consult the documentation for the device that you are connecting to the Adept
controller.
b
You may connect to pin 20, but V
+
ignores this signal.
