INSTALLATION INSTRUCTIONS

291-80

CFL FRIENDLY INFRARED RECEIVER

The 291-80 is a small shelf-top infrared repeater assembly. It is a CFL (compact fluorescent light) friendly version of the 291 Hidden Link series. It is specifically designed to have great immunity to CFL type infrared interference and to have exceptional IR reception range. In addition, the 291-80 will operate in direct sunlight!

IR Receivers & Modems

The 291-80 is equipped with a 7-foot cable and 3.5

mm stereo mini plug, which is plugged directly into

the "IR RCVR" jack on the CB12 (included). It can

also be plugged into the "AUX" or "IR RCVR" jack

on other Xantech connecting blocks, such as mod-

els 789-44, CB-60 and 791-44. The mini plug

provides quick installation where the connecting

block is within reach of the 7-foot cable — as when

installing the 291-80 in a cabinet where the con-

trolled equipment is behind closed doors. How-

ever, the cable length can be easily increased to

accommodate any desired application. See Fig. 4.

Fig. 1 The 291-80 in a Typical IR Repeater

In this system a 286M Dual Blink-IR Emitter is shown connected to the "OUT" jack. A single emitter could also be used, such as the model 282M or 283M. If expansion beyond two emitters is required, use a Xantech 789-44, CB-60 or 791-44 Connecting Block in place of the CB12. Do not use the CB12 in this case.

Adjustment

The 291-80 is factory set to an IR carrier repeat frequency of 38 kHz.

This will be correct for the majority of installations. However, some Fig. 2 IR Carrier Frequency Adjustment manufacturer's components that you wish to control may use different

carrier frequencies (such as the RCA DSS receivers that use 56 kHz). If such carrier frequencies fall within the range of 32 kHz to 56 kHz, you can adjust the 291-80 to match them for best range performance. The adjustment can be made through a small opening on the rear panel. See Fig. 2.

To adjust, proceed as follows:

1.First, try the 291-80 in a repeater system. If it works well with good range, do not make any adjustments!

2.If it does not work or has poor range (less than 15 feet), determine the IR carrier frequency of the product you wish to control. Contact the manufacturer of the product, if necessary, to determine this frequency.

3.Using a small blade type screwdriver (3/32" blade width max.), rotate the adjustment shaft until the slot lines up with the desired frequency marking. Refer to Fig. 2.

NOTE: The frequency markings shown in Fig. 2 are approximate only. You may need to "fine tune" the adjustment for best performance.
