CONTROLS AND INDICATORS:
Controls
The CNTV has an IR receiver on the front-right side, located above the CNTV label. Verify that the receiver
is in a line-of-sight path and unobstructed. The LED flashes when IR is received, confirming a good line-of-
sight path.
CAUTION
Direct sunlight or other light sources may prevent the unit from working properly by
desensitizing the CNTV IR receiver.
All CNTVs contain an IR receiver port, two IR outputs, two power sensors, four VersiPorts, two serial
ports, and a CRESNET port. The IR receiver port receives signals from the MRHC transmitter. The two IR
outputs are designed to work with IR controlled devices including TVs and other classroom equipment.
The digital connector of the CNTV-CS (supplied) attaches to the DIGITAL IN/OUT back panel connector of
the CNTV. The CNTV-CS senses whether a single television set (9" color or larger) is OFF or ON. The
NET port is provided for connection to the Cresnet system. There are four bidirectional TTL lines (or
VersiPorts) on the unit which are capable of sensing TTL voltage levels, analog voltage levels, or contact
closures to ground. They can also output TTL/CMOS logic levels. These lines provide control or sensing of
additional classroom equipment (i.e., security systems).
