External Device Connector Pin Assignments
C-5
014–001867
NOTE: VAC/16, VDA/128, and VDA/255 boards are factory-configured as Data
Communications Equipment (DCE). The female device connectors on
your junction and cluster boxes are also DCE.
VAC/16 controllers connect to their 8-port junction boxes through a
data-transmission cable with either 64- or 68-pin connectors at either end.
The signals and pin assignments for these connectors are identical except
for the last four pins of the 68-pin connector, which are not used. Refer to
the HPS VMEbus Multiplexer (HPS-6236/6237) Technical Manual for
detailed information.
VDC/8P Parallel Port Connector
Parallel printers connect to the system through 36-pin connectors located on the
back of VDC/8P controller boxes. Figure C–2 shows the signals and pin numbers for
parallel printer connectors.
