4.If you have products in the same IR system that have different IR carrier frequencies, you will have to adjust the 291-80 to a midway position. For example, some products may operate at 38 kHz and others at 56 kHz. In this case, set the adjustment to approximately 47 kHz, a midway position just to the right of the 48 kHz marking in Fig. 2.

NOTE: Some products are more tolerant of compromised frequency settings than others. You may have to "fine tune" the adjustment to "favor" the least tolerant component for the best performance of all units in the system.

Connecting IR Receivers From Other Rooms

The CB12 Connecting Block, supplied with the 291-80, has a three terminal input strip for connection of external infrared receivers should you wish to control your equipment from other rooms.

•The terminals are marked V G S. (V= +12V, G=Ground and S=IR Signal).

•Make connections as shown in Fig. 3. Run a 3-conductor cable from each remote room to the VGS terminals on the CB12.

(Use 24 gauge solid or stranded wire up to 200', 22 gauge up to 600', 20 gauge up to 2000' and 18 gauge up to 5000' (unshielded OK).

•When you use a 291-10 or a 291-80 IR Receiver in a remote room, do not plug in a power supply or use the "OUT" jack on that par-

ticular CB12, as shown in ROOM 3 of Fig. 3.

•You may use more IR re- ceivers, in additional rooms, connected in the same man- ner. When connecting more than ten 291-80's, use the higher current power sup- ply, Model 782-00.
