escription
The Model HR-3P is a programmable serial device with 3 video inputs VGA, Composite
Video (CV) and S-Video (Y/C). The VGA input supports all PC resolutions to 1600x1200 and
the TV video inputs are NTSC, PAL, and SECAM compliant. The unit has a VGA splitter with
2 VGA outputs, but the CV and S-Video have only one output each (pass through). The
HR-3P can detect video on any of the inputs and issue preprogrammed serial commands
via its RS-232 port. It also features 1 discrete (digital or contact closure) input and 1
discrete output. The discrete input can be used to issue commands on its high-to-low, and
low-to-high transitions. The unit also keeps track of ON/OFF state of the projector and
outputs a TTL (hi/lo digital) signal on its discrete output line for controlling other external
devices such as lowering and raising a screen. The HR-3P is an ideal tool for the
automation of a projector.
The commands sent to the projector can be any ASCII (or non-ASCII) data with
programmable delays embedded in the string.
Hall Research Technologies, Inc. provides a powerful Windows™ based application that is
used to create the data files and upload it to the HR-3P.
