Port B
Serial port B transmits data to and from peripheral devices. Port B can be
configured for either RS-232 or RS-422 communications using the
softkeys on the operator panel (see your 9/Series Operation and
Programming manual). Figure 5A.3 shows this connector and lists the pin
assignments of Port B.
The MTB panel may have the optional serial interface connector mounted
on it. This connector provides an external interface port for RS-232 or
RS-422 interface from a peripheral to the control. It communicates with
ports A or B with cable C07. Refer to the page 7A-22 for additional
information on cable C07. For more information on the signals of each
pin, refer to page 8-7.
