3-5 TPS150 Switching and Transmission System • Operation
Press the Projector Power button on the transmitter to issue the projector on or off
command. When you push the button, the following occurs:
• If no command has been transmitted since transmitter power was applied, or
if the power off command was the last command transmitted:
 The transmitter sends the power on string to the receiver on the TP link.
 The transmitter lights its Projector Power LED.
 The transmitter starts its power off timout function (if enabled).
 The receiver outputs the received serial string on its RS-232 port.
Some projectors use the same command for power on and power off. If the
same code is specified for on and off, the Projector Power LED blinks for each
button push.
• If the power on command was the last command transmitted:
 The transmitter sends the power off string to the receiver on the TP link.
 The transmitter turns off its Projector Power LED.
 The receiver outputs the received serial string on its RS-232 port.
The same sequence of events occurs when the projector power timeout function
(if enabled) expires.
