Transmit Undecoded Arc Commands - RFXCOM RFXtrx433 Manuel Utilisateur

12. Transmit undecoded ARC commands.

Plug-in modules or other equipment with a PT2262 can be controlled using Lighting4.
There are a lot of brands using the PT2262 and some of them use the same timing (350) as used
by the ARC devices but a different protocol definition.
Messages will be received as undecoded ARC messages if the protocol definition does not match
the definition of the ARC protocol. Remote commands are received as ARC commands with a
wrong house and device code and/or command code or as undecoded ARC messages if "undec
on" is enabled. Decoding of these remotes is therefore not possible because they overlap the ARC
protocol partly.
But transmitting these commands is possible using the Lighting4 command.
So if we receive this command UNDECODED ARC:18014403:
(18 is not used)
hex to binary table
0=0 0 0 0
1=0 0 0 1
2=0 0 1 0
3=0 0 1 1
4=0 1 0 0
5=0 1 0 1
6=0 1 1 0
7=0 1 1 1
8=1 0 0 0
9=1 0 0 1
A=1 0 1 0
B=1 0 1 1
C=1 1 0 0
D=1 1 0 1
E=1 1 1 0
F=1 1 1 1
0 1 4 4 0 3 = selection box 0000 0001 0100 0100 0000 0011
Not selected = 0, box selected = 1
And the Lighting4 command contains the same "undec code" 01 44 03:
Lighting4 command:09 13 00 04 01 44 03 01 5E 00
pulse timing is 350 = hex 015E
Another example:
For this command UNDECODED ARC:18014430 set on the Lighting4 tab in RFXmngr selection
box 1 to 24 to 0 1 4 4 3 0 = 0000 0001 0100 0100 0011 0000
