Using IR “Eyes” with the CK2.2
Connecting a Local Device
Every keypad can control a local IR source(s) by directly connecting IR
emitters from the keypad to the local source. A two conductor cable
should be run from the keypad location to the local component location.
Up to four infrared emitters can be wired to a keypad by connecting in
SERIES as shown below.
Multiple emitters shoudl connect in SERIES! When connecting emitters directly to the
keypad, multiple emitters should be connected in series. A maximum of 4 emitters can be
connected directly to the CK 2.2 keypad. Additional resistance is not necessary when
directly connecting emitters to the CK 2.2 keypad. Wire requirements for emitters vary.
Standard 2 conductor speaker wire is ideal for long runs from the keypad to a local
device. Utilizing CAT-5 cable will also work well.
Sometimes additional IR receivers are required in some rooms in addi-
tion to the CK 2.2 keypad. If additional IR recievers are used in a zone,
they should be treated like a slave keypad. Run a cable from the CK 2.2
to the IR receiver in the zone. The IR receiver should be pinned from
the Alternate Master (In) of the CK 2.2 keypad according to the connec-
tion figure below.
