Pelco Manual C930M-E (12/95) 3
NOTE: These cables are designed for use
in inverted applications. If you wish to modify
the cable for upright operation, pins 3 and 7
(pan) and pins 5 and 6 (tilt) need to be re-
versed on the 14- or 28-pin connector (pan/
tilt side). The problem can be corrected in the
field with a CPC pin/socket extracting tool
by simply exchanging the pins for these func-
tions. If you do not have the necessary tool,
contact Pelco for a R/A number to exchange
the cable.
