Connecting the HR-1P to the serial
device
• Connect the HR-1P to the serial device (projector) via
the serial interface using the supplied programming
cable.
• When connecting the HR-1P to the serial device
(projector) you must use a crossover serial cable in
addition to the supplied programming cable.
• This will connect the TX line of the serial interface on
the HR-1P to the RX line on the serial interface of the
serial device (projector).
• Without a crossover serial cable between the supplied
programming cable and the serial device (projector),
the serial device (projector) will not receive any
commands from the HR-1P.
• Connect the dry contact closure wiring to the EXT
CTRL input to the HR-1P. If you’re using a HR-1P-
OPTO version, connect the external power source to
the EXT CTRL input of the HR-1P.
• Connect the supplied Power Supply to the HR-1P and
you are done.
