System information

GPIO and Remote Connections in MX Ultranet and MX Sync
Vicon MX Hardware System Reference B-5
The example in Table B-4 shows the status events output by the GPIO
after the remote action has been triggered by a Kyowa-Dengyo Force
Plate (where High=5V and Low=0V).
Remote Functionality
To remotely trigger data capture on the Vicon MX system or to send
synchronization signals, you must either:
• Create your own external switch or photoelectric sensor to trigger
the remote capture, and connect it to the GPIO & Remote socket
on the MX Ultranet.
• Create your own synchronization interface, and connect it
between the GPIO & Remote socket on the MX Ultranet and your
external device.
• Connect the MX Ultranet 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 for connecting your third-party
device that supports general purpose input/output, you must use a
15-pin D-type connector. For details on the circuitry involved and
electrical specifications for the connector, see GPIO & Remote
Connector on page B-1. This section describes the operation and
output status events for remote control functionality.
