IR Codes
IR wavelength is 950 nm. Light is modulated at 38 KHz with 1/3 duty
cycle.
An on pulse must be at least 158 µseconds (µs) long (6 cycles) and
should not be longer than 448 µs (17 cycles).
From the start of a pulse till the start of the next pulse is 1050 µs for a “0
bit”, and 2000 µs for a “1 bit”.
A Flash is 11 pulses (10 bits), minimum time between flashes (interflash
time) is 11 mseconds (ms). When using the small eye the minimum interflash
time is 25 ms, 30 ms is recommended. There is NO preamble.
Channel 1 OPEN sequence is 0101000010. The sequence always starts
with 01, so for simplicity strip that off, and we get 0100 0010 = hex 42 (see
figure below).
Please Note: low = off, high =38 KHz signal on.

IR Eye Only
A Note on Wiring
The IR Receiver Eye must be plugged in to an open "Eye" jack (see diagram
on page 1). All input devices connect using electrically straight 4-conductor
modular cable.
Please note: If you use standard telephone cable, you must first remove one
connector, turn it over and re-attach, to ensure that the cable is electrically
straight (see diagram below).
** If you select any undefined layouts, the result is a standard T12 without
shift.
Front LED Blinks Indicate Selected Layout:
The Red LED on the front of the transmitter, in the upper left corner, will
blink to tell you which layout is selected when either of the following occurs:
-Batteries are removed and reinserted at the completion of the button 6+7
sequence to select a layout, or
-The blinks are long and short. Each long blink indicates 5's and each
short blink indicates 1's, with the sum indicating the currently selected
layout.
If the LED does not blink when batteries are inserted, press and hold any
button, then remove the batteries. Then release all the buttons and reinsert
the batteries watching for the blinks.
