Vicon MX Hardware System Reference A-7
GPIO Electrical Specifications
Table A-6 provides electrical specifications for the GPIO socket
(GPI=General Purpose Input, GPO=General Purpose Output).
Remote
To remotely trigger data capture on the Vicon MX system or to send
synchronization signals, you must do one of the following:
• Create your own external switch or photoelectric sensor to trigger
the remote capture, and connect it to the Remote port on the
MX Control.
• Create your own synchronization interface, and connect it
between the Remote port on the MX Control and your external
device.
• Connect the MX Control to an MX Sync, which provides an
interface to both remote triggering and synchronization
functionality, and then connect the MX Sync to the external
device. For details, see Chapter 8 MX Sync.
If you create your own interface, you must use a Lemo
FGG.1B.307.CLAD52 mating plug. This section describes the circuitry
involved and the electrical specifications.
Table A-6: GPIO Socket Electrical Specifications
Component Specification
GPO Optically isolated
Maximum External Voltage
Load
18 V when controlling devices
connected to an external voltage
source.
All GPOs are driven from a single channel of the output optocoupler.
Each open collector output is connected internally to the +5 V 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 0 V-4.3 V.
GPI Optically isolated
All GPIs are connected directly to one channel of the high CMR
optocoupler. Connecting any one of these inputs to 0 V activates the
required function.
