Appendix D -- I/O Connections for the PCI4 -- Miscellaneous I/O Connector
6-14
Miscellaneous I/O Connector
This connector contains a number of chassis ground related signals. It is the miniature 15 pin female D shaped
connector on the PCI4 Controller Card. Be careful, the ground on this connector is not the PCI4 floating
ground. Connecting the two grounds may lead to problems if you are using the PCI4 in a floating mode.
The auxiliary analog output, derived from a D/A converter, is on this connector. The scaling is normally 2.5 mV
per bit, for a
±
5 volt full scale range. These ranges can be altered via the AUXDACRES field in the
"GAMRY5.INI" file.
The pin out of this connector is shown in Table D-3.
