Model HR-1P Projector Controller
Description
The Model HR-1P is a programmable RS-232 serial device
designed for control & automation of a Projector, LCD, or
any other device with serial port.
The HR-1P has a discrete input that senses a dry contact
closure (or Voltage Level). It detects both “Low-To-High”
and “”High-To-Low” transitions of the ‘EXT CTRL’ input and
issues corresponding commands out the serial port of the
HR-1P to the serial device (projector).
The commands can be any ASCII (or non-ASCII) data with
programmable delays embedded in the string. The
commands can also be complex multi-part strings typical of
many modern projectors. The unit can be configured to send
the output string once or to repeat continuously per
transition of the ‘EXT CTRL’ input.
Hall Research provides a powerful Windows® based
application (available on-line) that is used to create the data
files and upload it to the HR-1P, via a supplied cable.
