Infrared (Ir) Operation - OPTICOM 764 Installation Manual

9.6 Time Sync Output
Skip this section if this function is not going to be used.
The Time Synchronization Output feature makes use of the highly accurate Atomic clock time data that is
available from the GPS system. Using the GPS time information, an output can be activated which can be
used to reset the clock in a traffic controller or other equipment in a traffic cabinet.
1. Using the On-site software enable the time sync output and set the time, pulse width, output and
frequency as needed. See the On-site help file for more detail.
2. Connect a wire from the AIP output specified above to the clock reset input on your controller.
3. Connect a wire from one of the Logic Common terminals on the 768 AIP to Logic Ground on your
controller.
9.7 Output Inhibit
Skip this section if this function is not going to be used.
The output inhibit function allows you to use an external source to inhibit (shut off) all outputs on the phase
selector and the Auxiliary Interface Panel.
A typical use would be for the traffic controller to provide an output which would be used to turn off the
outputs from the Opticom system during rail or draw bridge preemption. In this scenario the Opticom
system would be prevented from placing emergency vehicle preemption calls or TSP calls while the traffic
controller is servicing a rail or draw bridge preemption call.
Typically rail and draw bridge preemption calls are given a higher priority in the traffic controller than
emergency vehicle or TSP calls. Therefore using this output inhibit feature on the Opticom equipment tis
typically not necessary.
1. Connect a wire from the 768 AIP CTRL 24V terminal to the controller 24 VDC source.
2. Connect a wire from 768 AIP INHIBIT terminal to a controller terminal that provides aground when you
want the inhibit function to be active.
3. The no preempt cause as seen in the On-site current activity screen will be "Inhibited by External Input"
for any calls that are being prevented by the inhibit input.

10 Infrared (IR) Operation

If you will be operating in Infrared only or simultaneous Infrared/GPS operation, see the model 711/721/722
installation manual for details on locating, mounting and wiring infrared detectors to the phase selector. You
may also reference the Model 762, 764 manual for more information on infrared operation.
