device power state if the previous command was ineffective. This is based off the reading of the
sync sensor or the I/O port that is connected to the Power Current Sensor (depending on the
method used to detect power – see sections 4.1.3.2 and 4.1.3.3 for more information regarding
power sensing). This setting is critical to the proper functioning of the Television Manager. If the
value is too small then the display device may “cycle,” meaning that the Television Manager will
send a command to change the power state and then, before the device has time to react, the TM
will repeat the command, causing it to revert back to its initial power state. This may continue
infinitely, making the room unusable and possibly damaging the display device. This value is
measured in 10ths of seconds. Therefore, to set a value to 5 seconds, you would enter the value
of 50. If you enter only the number 5 then you will be setting the corresponding timing parameter
to ½ second.
Q
R
RS-232 / RS-422 – An industry data protocol commonly employed by manufacturers of
audio/visual devices to provide advanced remote control capabilities.
Router – This term has two possible meanings within the context of Phoenix: (1) a device used to
manage TCP/IP traffic, ensuring that packets of data reach the correct destination, and (2) a
device used to send audio/video signals to the correct destination. The audio/visual router is

S
String – A sequence of character data.
Surf Ring – A synonym for Channel Ring. See definition of Channel Ring.

Synergy – The Synergy Media Retrieval and Campus automation application was the
predecessor to Phoenix. Synergy communicates only with the obsolete Axcess control system.
Synergy became freely available as an Open Source application after AMX Corporation decided
that the solution was no longer within the core vision of the company.
T
TCP/IP – TCP/IP is the industry standard communication protocol used by networks to enable
communication between electronic devices. The term is an acronym that stands for Transmission
Control Protocol / Internet Protocol.
Television Manager – Also referred to as a “TM,” this device is a set-top box that communicates
with a display device either by infrared or RS-232 to control the power state, tuning, volume, etc.
