InfraRed (Global Cache)

InfraRed (Global Cache) control integration with LogicMachine #

Task #

How to control your AV equipment with Global Cache IR controller, from KNX and LogicMachine visualization?

Sending IR commands #

IR controllers from GC-100 or iTach family from Global Cache can be used for transmission. LogicMachine is connected to the IR controller via TCP/IP.

GC command string format #

Command,Modul:NumDev,Id,freq,Repeat,Оffset,P0,..,Pn^ (without spaces)

  • Command - Command for execution by controller of Global Cache. To transmit IR command Command=sendir. See full list in the Global Cache documentation.
  • Modul - The module containing the appropriate IR port (e.g. for iTach=1)
  • NumDev - Number of port in the module starting with 1
  • Id - Id number of the command in range 0 – 65535
  • Freq - IR channel frequency in Hz, from 20000 – 500000
  • Repeat - on 0 – repeat the command up to 65535 times or while the command transmit is terminated
  • Offset - Time period to repeat the telegram in the next transmissions (Repeat<>1), 1 – 255
  • P0,...,Pn - String sequence defining impulse sequence in IR telegram
  • ^ - Symbol defining the end of command string (\r)

Event script example #

Modify ip, port and cmd as needed.

ip = ''
port = 4998
cmd = 'sendir,1:1,1,37650,1,1,' ..
  '341,171,21,21,21,21,21,64,21,21,21,21,21,21,21,21,21,21,21,64,' ..
  '21,64,21,21,21,64,21,64,21,64,21,64,21,64,21,64,21,21,21,21,21,' ..
  '21,21,64,21,21,21,21,21,21,21,21,21,64,21,64,21,64,21,21,21,64,' ..

sock = require('socket').tcp()
res, err = sock:connect(ip, port)

if res then
  log('connect failed', err)

IR command definition #

Sequence of P0,…,Pn can be received:

  • from Global Cache database of IR commands
  • by scanning IR commands

For scanning you will need:

  • Scanner of IR commands, e.g., Global Cache iTach IP IP2IR
  • Scanning application Global Cache iLearn
  • PC with communication possibility with iLearn and scanner

iLearn #

Infrared globalcache_logicmachine_command

After receiving a telegram from the IR remote in the Edit View window the string will appear defining the command to use with the IR control channel from LogicMachine.
