Model 5150
Video Generator Module
Optical SDI Input
If supported by the specific Model 5150
module being installed, an HD- or 3G-SDI
signal transported on a single-mode opti-
cal fiber can be connected. For an input to
be present a video SFP transceiver or a
receive-only SFP module must have been
installed in the SFP “cage” in the back of
the unit. The optical receiver circuitry in an
SFP module is “broadband” and doesn’t
need to receive a specific wavelength of
single-mode optical signal for correct op-
eration. As long as the optical signal has a
wavelength between 1250 and 1650 nano-
meters and meets the applicable SMPTE
standards it will be recognized correctly.
A single-mode optical fiber terminated
with an LC plug can be connected to the
receive port on the SFP module. This port
is on the right side when looking directly at
the back of the SFP module. Typically there
will be a graphic arrow icon pointing “in” on
the top of the module. Refer to Figure 2 for
details on the location of the SFP module.
Ensure that the LC plug fully “mates” with
the receive port and its tab is locked into
the slot of the SFP module.
A configuration switch must be appropri-
ately set to enable the optical SDI input.
There is no automatic switching between
the optical and coaxial (BNC) SDI inputs.
Only one of the two SDI inputs can be
selected and active at a time. Refer to
the Configuration section of this guide
for details.
DC Input and Data Bus
A 4-position header is used to connect DC
power and a local RS-485 serial data bus
to the Model 5150. Two pins on the mating
connector are used to connect a source
of nominal 12 volts DC. The acceptable
range is 10 to 18 volts DC with a maximum
current of 400 milliamperes at 12 volts DC.
For remote control operation two pins on
the mating connector will implement the
data bus connection from a Studio Tech-
nologies’ Model 5190 Remote Access
Module.
The mating connector is compatible with
the AMP MTA-100 series of IDC recep-
tacles. For 22 AWG wire the closed-end-
style receptacle is AMP 3-643813-4; the
feed-through-style receptacle, used for
busing connections, is AMP 3-644540-4.
The body color for both receptacles is red,
following the convention of the MTA-100
series for compatibility with 22 AWG wire.
Refer to Appendix B of this guide for addi-
tional connector details.

Mounting
The Model 5150 is intended for mount-
ing in an installation-specific enclosure or
rack panel. Refer to Appendix C at the end
of this guide for details on the required
mounting opening and screw locations.
Please contact the factory to discuss
mounting options.
