Section 4

Adding the IR Blaster Option

The IR Blaster provides control of the subscriber’s VCR from the DCT2500. It consists of a low-power infrared transmitter attached to a six-foot cord and a mounting bracket. The mounting bracket is a clear plastic holder with a pad of adhesive tape for installing the IR Blaster near the VCR IR receiver. A mini-pin connector at the end of the cord connects the IR Blaster to the DCT2500.

Figure 4-1 IR transmitter installed in mounting bracket

Adhesive tape

Mounting bracket

Transmitter

The IR Blaster is controlled by the interactive program application on the DCT2500. Not all applications support the optional IR Blaster.

The IR Blaster is automatically activated through the EPG. Individual VCR codes are broadcast through the out-of-band data channel and are updated periodically as new codes are added.

Locating the IR Receiver on the VCR

The IR receiver is not visible on some VCRs.

To locate the receiver:

1 Obtain a piece of opaque material, such as a 3- by 5-inch index card.

2 Use the card to block areas of the VCR where the receiver might be located. Turn the VCR

on and off, while pointing the remote control at the card blocking the VCR. Be sure the remote control is close to the VCR to reduce reflections the receiver may pick up.

3 Note the area where the VCR is unresponsive to the remote control. This region contains

the receiver and can be marked by loosely taping the index card to the area.

Because the IR Blaster radiates an area approximately 40 degrees wide, it is not necessary to be precisely on target with the remote control. Offset the location of the IR Blaster transmitters from the VCR receiver to reduce interference with operation of the VCR remote control.

DCT2500 Installation Manual

Installing the IR Blaster

To install the IR Blaster:

1 Fit the transmitter into the mounting bracket (refer to Figure 4-1).

2 Plug the mini-phone connector into the IR jack on the rear panel of the DCT2500 rear panel
