IR-RC5 Definition

How is the RC5-Code constructed?

RC5 is the most often used Remote Control Code

which is also being used by Revox. Each RC5

codes consists out of 14 BIT, which are successive

send to the receiver:

• 2 Startbits (always “1”)

• 1 Toggel bit (alternating 1” or “0’)

• 5 Address bits

• 6 Command bits

The Startbits are used to synchronize the IR-

Receiver with IR-Transmission. The receiver

adjusts its amplification settings on to the signal.

The Toggelbit changes its value with each press of

a button. That way the long pressing of a button can

be differentiated from the alternating pressing of the

same button.

The address bits define the device. Up to 32

devices can be controlled.

The command bits contain the commands of the

device. Like that up to 64 different commands can

be send for each device.

The carrier frequency for each device is 36 kHz.

RC5-Code of the M208

Is a device defined as a RC5-Code in the mpi-file the

address and the command has to be indicated. Start-

and Toggelbits are generated automatically from the

M208. Address and commands are indicated in

hexadezimal digits.

Syntax:

Hardkey /Softkey = $ [Address][Command] (hex)

Examplel: Revox DVD

Address DVD: 14 h

Command Sound: 2B h

Sound = $142B ⇐ Softkeys

Angle = $141F

Subtitle = $142D

Setup = $1435

NUM_0 = $1400 ⇐ Hardtkeys

NUM_1 = $1401

NUM_6 = $1406

NUM_7 = $1407

NUM_8 = $1408

NUM_9 = $1409
