Rear Panel Features
HD-SDI Input and Output
Each screen has one HD-SDI input and one active
loop-through output. Note: No more than 4 screens
should be connected in one loop.
Power Input
Connect the 12VDC input to the 2-Pin twist lock
power input connector. Power can be supplied from
the included power supply, or from a variety of DC
sources supplying at least 6.0 Amps at 12 Volts.
IMPORTANT: If using a power source other than the
included power supply, be sure that the polarity of
the DC input is correct:
Tally Interface (HD-15)
Both LED tally and OSD tally can be activated via
the HD-15 connector by connecting the
corresponding pin to ground. A variety of external
devices can be used to perform the contact closure.
No additional power should be supplied to the HD-
15 port. See pin-out details on page 26.
RS-422/485 Serial Interface
The RS-422/485 ports are used to remotely control
the IMD or all V-R653SB-IMD features, using a
variety of industry standard protocols. (Note:
Connector/pin-out may need to be adapted
depending on protocol and controlling device
used. See pin-out details on page 26.) Only one
connection to either port is needed to control the
monitor. The second port can be used to loop
multiple monitors in the same bus.
