Remote Electrical Specifications
Table A-10 provides electrical specifications for the Remote socket
(GPO=General Purpose Output).
Table A-10:Remote Socket Electrical Specifications
Component Specification
GPO Optically isolated
Maximum External Voltage
Load
18 V when controlling devices con-
nected to an external voltage source.
The GPOs are driven from a single channel of the output optocoupler.
Each open collector output is connected internally to the +5V supply
via a 270
Ω resistor and a diode. This output behaves in a similar
manner to a TTL signal. When connected to a high impedance load,
the output swing is between 0V-4.3V.
Remote Start Optically isolated
Remote Start is connected to one channel of the high CMR
optocoupler. Connecting any one of these inputs to 0 V activates the
required function.
Remote Stop Optically isolated
Remote Stop is connected to one channel of the high CMR
optocoupler. Connecting any one of these inputs to 0 V activates the
required function.
Gated Reference
Amplitude 2V peak to peak when terminated in

Ω
Pulse Direction Negative going
Pulse Duration
80
µS
Pulse Frequency Once per Vicon video frame (only
enabled during capture)
This signal goes low for 80
µS when the system is either armed or
capturing. At all other times it stays high.
