Model URA-RS232
Description
The Model URA-RS232 is a standard VGA-plus-Audio over Cat5
Receiver with the added feature of having a programmable RS-232
serial device port for the control & automation of a Projector, LCD,
or any other device with serial port.
The URA-RS232 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 URA-RS232 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.
Hall Research provides a powerful Windows® based application
(available on-line) that is used to create the data files and upload it
to the URA-RS232, via a supplied cable.
