NOTE: Each cluster controller package includes a 100/120 volt power cord, shipped with the
controller box. If your site requires 220 or 240 volts ac, make sure you received the
correct number and type of additional power cords; do not attempt to use the 100/120
volt ac cords.

Asynchronous Serial Port Connectors
Serial devices connect to the serial ports through RS–232–C 25-pin female DB25
connectors. Asynchronous connectors are located either on a VDA/128 (and
VDA/255) cluster box or on a VAC/16 junction box. Figure C–1 shows the signals
and pin numbers for these asynchronous connectors.
