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).
