IR Codes for Non-Polycom Remotes
This appendix provides information about the IR signals for VSX systems.
Notes
•
Wake up – 2.6ms on 2.6ms off
•
“0” – 559us (22 pulses@38KHz) on, 845us (33 pulses@38KHz) off
•
“1” – 845us (33 pulses@38KHz) on, 1192us (46 pulses@38KHz) off
•
EOM – 559us (22 pulses@38KHz) on
•
System code – “00110101” or 35 hex
•
Parity – “00” for even, “01” for odd, and inverts every other time. For
example, if parity is odd, first key press is 01, next is 11, next is 01, etc. The
first bit is the toggle bit; the second bit is the parity bit.

•
Inter-burst timing – 2200 pulse times @38.062KHz or 57.8ms
•
38.062KHz signal – at 1/3 duty cycle to LED
