Polycom RealPresence Group Series Specifications
Polycom, Inc. 424
Remote Control
This section provides information about the IR signals for RealPresence Group Series systems.
Notes
● Wake up – 2.6 ms on; 2.6 ms off.
● 0–559 µs (22 pulses at 38 KHz) on; 845 µs (33 pulses at 38 KHz) off.
● 1–845 µs (33 pulses at 38 KHz) on; 1192 µs (46 pulses at 38 KHz) off.
● EOM–559 µs (22 pulses at 38 KHz) on.
● System Code consists of a User ID field (upper nibble) and the Polycom Vender Code (lower nibble)
with value 0x5. The default User ID value is 0x3, so the default System Code value is 00110101 or
0x35.
● Parity is a 2-bit field consisting of a parity bit (b1) and a toggle bit (b0). Parity is even.
● Inter-burst timing is 2200 pulse times at 38.062 KHz or 57.8 ms.
● 38.062 KHz signal is at 1/3 duty cycle to LED.
● Multi-bit fields are transmitted most significant bit first.
● Bits are labeled b0..bn, where b0 is the least significant bit.
