DESCRIPTION:
Functional Description
The CNTV, illustrated in figure 1, is part of the MRMT-21 RF Classroom System or may be used
separately as a Cresnet network device. Regardless of the system, the primary function of the CNTV is to
accept and process system commands to control televisions or other associated audio/video devices in a
remote location. The scope of this document provides technical information of the CNTV as a stand-alone
Cresnet network device. Refer to the latest revision of MRMT-21 (Doc. 5602) for operation of the unit
within the MRMT-21 system.
Physical Description
The CNTV is housed in a black enclosure with silk-screened labels on the front and back of the case. On
the front, there are five red LEDs for indicating the current status of the unit. All connections are made on
the back of the unit.
There are four rubber feet on the base of the unit for stability and to prevent slippage. If necessary, the
user can apply Dual Lock fasteners to the unit's underside. The rubber feet do not need to be removed. The
fasteners may be preferred for additional stability when mounting the unit onto the surface of a TV.
