MPT -90 MODELS
MPT models are designed to have the maximum amount of features and flexibility in
connectivity based on our experience in remote controlled positioners. The MPTs
feature two “Payload Port” connectors (one per side) that allow the user to wire their
payloads to the positioner providing multiple power and control options.
All models provide the following conductivity to EACH of the payload ports:
Four 8-Amp conductors designed for power (up to 210 VDC, 240 VAC) to the
payloads. These conductors are shared between the two payload ports and
the base connector
Two analog (±12 VDC) variable speed drivers designed to drive Zoom and
Focus motors, but may be used for other devices such as low power motors
or lighting.
Two analog inputs, designed to read position potentiometers for Z/F lenses.
These are useful when combining with stored positions to assure consistent
camera framing of objects of interest.
One Auxiliary power source, configurable for 12 or 24 VDC, with on/off
switchable control
One Auxiliary power source, configurable for 5 or 12 VDC, with on/off
switchable control
Three serial ports, providing single ended (RS232) or differential (RS422)
communication between payloads.
Additionally, there are IP and Video signal paths between the base connector
and the payload port. In continuous rotation models, these signals pass through
the integrated slip ring, which creates limitations to the number of signals and
bandwidth that can pass through. The non-continuous rotation model (8-
PA166) does not have these limitation, and therefore has the higher bandpass
GigE and HD-SDI video connections on each payload port.
Each 10/100 IP signal path requires four conductors, while a GigE IP signal
path requires eight conductors. HD-SDI video requires different wiring and a
higher caliber of slip ring than conventional analog EIA - RS170 video, but not
all budgets can accommodate the higher cost of the HD-SDI slip ring.
For these reasons, several models have been created in various configurations,
and the table below shows the comparisons:
