Ethernet Enabled Programmable TV/AV Controller
24VDC, 20K ohms input impedance, logic threshold 1.25VDC. Digital outputs offer
250 milliamp sink from maximum 24VDC; catch diodes provide transient protection
for use with “real world” loads. Analog inputs are rated 0 - 10VDC, protected to
24VDC maximum, 20K ohms input impedance; pin-programmable 2K ohms pullup
resistor to +5V. The pin labeled
G
is the common ground for pins 1-4.
IR
This 3.5mm mini-jack is used by the STIRP (provided) to control an attached TV or
AV device. The jack accepts mono (2-conductor) or stereo (3-conductor) mini-plugs.
Multiple IR drivers may be loaded into the CEN-TVAV and a ST-SPL may be used
for control of multiple AV devices.
POWER OUT
WARNING:
When the POWER IN cord is plugged into an energized outlet,
POWER OUT becomes energized. Crestron recommends connecting the TV or AV
device
before
plugging the POWER IN cord into an outlet.
NOTE:
The maximum continuous current from the POWER OUT under any
external load shall not exceed a current limit that is suitable for the minimum wire
gauge and maximum length used for the interconnecting cable(s).
NOTE:
The maximum load applied to the POWER OUT shall not exceed the rated
voltage and current as specified on the unit.
This receptacle provides AC power (refer to the rear panel label for details) for a TV
or AV device. The receptacle is hard-wired to the POWER IN cord and is
NOT
protected with a fuse.
The power out receptacle may be programmed to sense whether the attached device
is OFF or ON. A large current detected by the receptacle is used to indicate that the
attached device is ON and the absence of (or very low) current indicates the device is
OFF. If the CEN-TVAV (or control system) detects that the device is ON, the
program can be coded to not allow the CEN-TVAV to attempt to turn it ON, which
would inadvertently turn it OFF. This is true if the IR driver does not have discrete
ON and OFF functions, but only a POWER function.
POWER IN
This attached power cord supplies operating AC power (refer to the rear panel label
and/or “Leading Specifications” section of this guide for details) to the CEN-TVAV
and the POWER OUT port. An internal fuse electrically protects the CEN-TVAV
circuitry from excessive power input.
