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
acceptandprocesssystemcommandstocontroltelevisionsorotherassociated audio/video devices in a
remotelocation.Thescopeofthis document provides technical information oftheCNTVasastand-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
TheCNTVishoused in a black enclosure with silk-screened labels on the front and back of the case. On
thefront,thereare five red LEDs for indicating the current status of the unit. All connections are made on
thebackof the unit.

NOTE This device complies with part 15 of the FCC rules. Operation is subject to the
following two conditions: (1) this device may not cause harmful interference, and (2)
this device must accept any interference received, including interference that may
cause undesired operation.
CONTROLS AND INDICATORS:
Controls
The CNTV has an IR receiver on the front-right side, located above the CNTV label. Verify that the receiver
isinaline-of-sightpathandunobstructed.TheLEDflasheswhen IR is received, confirming a good line-of-
sightpath.
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
outputsaredesignedto 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).

This red LED turns "on" when an IR signal from the hand transmitter is received by the CNTV.
MESSAGE

unit resides.
T and R
These two red LEDs "light" or flash rapidly when there is communication between the associated control
systemandtheCNTV. The LEDs should illuminate when power is supplied to the CNTV.
INSTALLATION/SETUP:
Optional Equipment
Due to variations in installation requirements, not all possible peripheral pieces of equipment are supplied
withtheCNTV.Table 2 provides a list of all optional equipment that can be used in conjunction with the
CNTV.

Identity Code
TheCNTVidentitycode (ID CODE) consists of a two-digit hexadecimal number. These codes are vital for
propercommunicationandtypically factory set. An ID CODE label is affixed to each unit. The ID CODE can
rangefrom03toFE.TheIDCODEofeachunit must match the ID CODE specified in the SIMPL Windows
programinorderforthedeviceto be addressed properly.
IftheCNTVIDCODEneedsto be altered, it can be set from aPCviaCNTVSETUPmenus.Referto the

Power Sensor Placement
Use a CNTV-CS (supplied) or power sensor loop (optional) to detect power from television or other
equipmenttobecontrolled.TheCNTV-CSshould be plugged into an AC outlet and thetelevisiontobe
current sensed is plugged into the CNTV-CS. The digital connector of the CNTV-CS is attached to the
DIGITAL IN/OUT back panel connector of the CNTV. Alternatively, a wire loop (as shown in figure 3) can
beconstructedandplacedintheelectromagneticfieldofthetelevision flyback transformer. Perform
PowerSensorTest(refer to Enter Test Menu in the Appendix of this guide) to determine if the device is
OFF or ON or in the electromagnetic field.
NOTE
The loop is less reliable than the CNTV-CS, since it depends heavily on position and
the low-power emissions of the television.

IR Probe Placement
PlaceaMRIRPover the IR window on a television or other equipment to be controlled. MRIRP must

on manually. If the TV does not respond to "MUTE" or "VOLUME" commands from the transmitter or
wiredpanel,changethepositionoftheMRIRP.
Preparation for Use
NOTE The CNTV should be powered from a 12 VDC power pack. Obtaining power from the
power pack and the network does not result in damage to the unit. If system design
prevents use of power pack (i.e., absence of AC outlet) contact a Crestron technical
support representative for power alternatives.
Crestronrecommendsspecificpowerpacksforits network devices. The recommended power pack for
the CNTV is Crestron part number PW-1205. If an external power pack other than this Crestron model is
obtained, verify that it meets the required specifications and polarity as shown in table 3.

DCPowerPackPolarity
Refertofigure5 for a typical hook-up diagram of the CNTV within a Cresnet system. Connecting cables
and hardware are not supplied with the unit, due to variations of installation requirements. Crestron
recommends that wall jacks with an RJ11 (6-6) receptacle be located in the room with a CNTV. Use a
telephonecableofappropriate length to connect the CNTV to the wall jack. Wire a Cresnet cable to the
four terminals at the rear of the wall jack.
CAUTION
The modular NET port on the CNTV requires unique wiring. Wiring the port according to
Crestron Network Modular Cable Requirements (latest version of Doc. 5682) will
result in damage to the CNTV.
Due to the wire order within the cable, the connecting color scheme is non-standard and illustrated in
Detail A of Figure 5. Local power is provided, so the fourth wire (+24V) is not needed. If a wall jack
connection is not an option, Detail A also illustrates a direct to Cresnet alternative. Detail B provides a
