Crestron electronic CNTV Preparation for Use, IR Probe Placement, DC Power Pack Specifications

CRESTRON CNTV Cresnet Television Control Unit

IR Probe Placement

Place a MRIRP over the IR window on a television or other equipment to be controlled. MRIRP must completely cover IR window and other extraneous light should be blocked with opaque tape. Turn the TV on manually. If the TV does not respond to "MUTE" or "VOLUME" commands from the transmitter or wired panel, change the position of the MRIRP.

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.

Crestron recommends specific power packs for its 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.

Table 3. DC Power Pack Specifications

CRESTRON POWER PACK	INPUT SPECS		OUTPUT SPECS
PW-1205	120VAC 60Hz	18W	12VDC 500mA

DC Power Pack Polarity

Refer to figure 5 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 telephone cable of appropriate 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 detailed illustration of the communication cable required if a wired panel is employed as an interface.
