Crestron CEN-TVAV 

Ethernet Enabled Programmable TV/AV Controller

In this description, a CNMSX-PRO is used as the host control system. It is also valid 
to use a CEN-TVAV as a master unit to slave CEN-TVAV's. As shown below, an 
RS-232 controlled VCR is physically wired to the CEN-TVAV. A macro exists that 
has PLAY, STOP, FFWD, REW, PAUSE and RX$ on the inputs and PLAY-F, 
STOP-F, FFWD-F, REW-F, PAUSE-F, and TX$ on the outputs. One way to code 
this is to put the macro into the CNMSX-PRO program and hook up the TX$ and 
RX$ to the TVAVCOM-1 port to control the VCR. It is recommended to put the 
macro inside the CEN-TVAV, and hook the TX$ and RX$ up to the TVAVCOM-1 
locally in the CEN-TVAV. The transport controls and feedback would be hooked up 
to the ISC symbol.

The two diagrams below show the control system side and the CEN-TVAV side 
ISC's. As an example of a signal path, the user would press a button on a touchpanel 
on the control system that would activate signal VCR-PLAY. The signal would be 
packaged for transport over Cresnet (containing the destination Cresnet ID, Slot 5, 
and Port 1). The receiving CEN-TVAV would decode it, and send it to Slot 5, ISC 1, 
Signal 1, which would activate the signal TVAV-VCR-PLAY which would in turn 
put the VCR into Play. The return path for TVAV-VCR-PLAY-F is similar.
