Prior to final installation of the wallplate, you need to use the supplied
Windows™ software and the serial cable to program the serial codes
needed to operate the projector into the sender wallplate.
Note on CV and S-Video Inputs
Do not connect the Composite Video and S-Video inputs
simultaneously. Doing so will produce a poor quality image
Note on RS-232 port availability on your PC
Most PCs and notebooks do not have a serial port. So to
program the sender you may need a USB to RS-232 Serial
converter. These are available from Hall Research Technologies
(Model USB-RS232-1).
Note on Uploading Serial Codes
For your convenience the wallplate sender has a power
connector. In the final installation this connector will be left
open. However, you can use the power supply that is included
with the unit to solely power up the Sender (with no RJ45
connections) in order to upload the serial codes. Of course,
when the RJ45’s are connected, with the power supply at the
receiver, you can still upload the serial codes as well.
