GPIO and Remote Connections in MX Ultranet and MX Sync
B-14 Vicon MX Hardware System Reference
PulsePeriod Section
The syntax for the PulsePeriod section is:
<PulsePeriod Frames="" MicroSeconds="" Ticks=""/>
where:
Important
If you specify Frames , MicroSeconds, and Ticks, all values are added
together to determine the offset.
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
PulsePeriod specifies the total period for a repeating
synchronization pulse signal, that is, the time from
one rising edge to the next rising edge, as either one
or the sum of two or more of the following values
converted to 27 Mhz:
Frames The number of frames after which the
pulse is to be repeated.
MicroSeconds The number of microseconds after
which the pulse is to be repeated.
Ticks The number of 27 Mhz clock ticks of
the MX timing reference after which
the pulse is to be repeated.
