OPERATION
The V-2927 Clock Control Card installs into connectors J3 and J4 shown in Figure 1. The output
connections are presented to the V-CIO Clock Interface Board via P2, DB15 male of the V-2927
Clock Control Card. Two independent clock ports, consisting of two normally open contacts
each, are provided. These ports work independently of each other and allow the system to
control two clock types simultaneously. A status LED is provided for each relay to indicate
activity. An administrative code, (#97XX, with XX being number of minutes to advance), is
provided to manually correct or advance various impulse clocks.
(Default code is 01).

The V-2927 must be installed prior to programming its available options.
