ICC1-232 TV Controllers deliver economical 1-way control for power, volume, channel and input commands, receiving iCC-Net network commands over the same broadband coax that carries the CATV channels. The ICC1-232 RS-232 employs a DB9 RS-232 port to control commercial-level TVs.
If needed, fix CATV problems before installing the system. 2. Connect the CATV RF Coax cable into the RF In input on the ICC1-232. 3. If the iCC-Net signal is operating, the Net LED will blink once per second.
Setting Device Number and Parameters In the next step, you’ll need to set up the device number and operation parameters for the ICC1-232. Turn the enclosure so that the DIP switches are on the bottom as shown. 1. Make sure S2 Switch 6 is OFF (unit in Device mode).
Power-Up and Lock Logic The ICC1-232 remembers the current power and Lock state of the connected TV so that the controller can restore power and operation lock to the TV when AC power is restored. Some TVs, such as LG, will lose the locked state (no local button or IR control) when the set loses AC power.

Tune HD “$A5,<dh>,<dl>,5,’TH’,<H1>,<Major>,<Minor>” (9 bytes) – Digital Tuning Normally, the H1 parameter is 0, allowing the ICC1-232 to use the current H1 tuning format, but it could be used to force a different tuning option. When the display is set to the H1=1 mode, 1-part digital channel, the first byte is (x*256), and the last byte is the value you add to state the channel number.
