14 Pelco Manual C1943M (9/99)
7. This brings up the GPI SETUP file dialog box (.GPI file). Refer to Figure 12.
8. Program logical GPI numbers for all the physical numbers that will be used. The physi-
cal GPI numbers correspond to a specific VCR control signal on the VCR controller.
These GPI numbers correspond to the same numerical “Connect GPI” numbers previ-
ously entered in the camera file.
9. For each associated GPI defined here, make sure none of the relay boxes have been
checked; that is, define all relays as momentary.
Figure 12. Configuring the GPI SETUP file for VCRC-P Operation
NOTE:
When writing mac-
ros to control VCR opera-
tion, keep in mind the follow-
ing:
The macro must reflect your
actual equipment configura-
tion; if you change the con-
figuration, you must adjust
the macro accordingly. For
example, if a macro were
written to control VCRs at-
tached to three VCRC-Ps in
a daisy-chained configura-
tion and one of the VCRC-
Ps was subsequently re-
moved, then any previously
written macro that included
these three VCRC-Ps would
have to be rewritten to re-
flect that change. Similarly,
changing the frame address
setting via SW2 on any of
the three VCRC-Ps would
have the same effect as
physically removing the unit
from the configuration (as
far as the macro is con-
cerned) and, as before, the
macro must be edited or re-
written to reflect any
changes made.
