The ICC1-232 RS-232 Display Controller delivers economical 1-way control for power, volume, channels, and available control lockout commands, receiving iCC-Net network commands over the same broadband coax that carries the CATV channels. Compact in size and price, the ICC1-232 features discrete power control and intelligent tuning from a channel list stored in onboard non-volatile memory. Tuning options include analog- and HDTV-format channels.

AC Power Test 1. Insert DC power supply plug into 12 VDC jack. 2. Plug power adaptor into AC wall outlet. 3. The Net LED should turn on and stay lit. RS-232 Control Wiring 1. Attach the CC-RS-232 or custom RS-232 cable to the ICC1-232 control port. 2. Connect the cable to the display’s RS-232 control input. RF Coax and iCC-Net Operation 1. Connect the TV to CATV and observe quality of RF broadcasting. A low-quality CATV system can also affect performance of the iCC-Net commands.
Installation 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). 2. Set the Device number by turning on the switches that add up to the desired device number.
Unit Address Switch Settings The unique address of the controller is the combination of the values of the Zone (S2) and Unit (S1) switches. For example, the first controller in Zone 1 would be set to Zone 1 (256) in S2 and 1 (1) on S2, or 257. To control all the displays in Zone one, Display Express sends a command to device 256. To control just the first unit, create a Preset addressed to 257.
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. Other sets may not automatically power back on when AC power is restored.
NEC –AVT TVS TV responds erratically to RS-232 commands, especially channel tuning. Note that older sets with AVT tuners may need a firmware update to perform consistently. If the set responds erratically to commands, often for channel commands, check with NEC support for firmware information. Also, we have two commands sets for NEC AVT sets.
Overview RS-232 control for up to 4000 TV Controllers is provided through an iC-series Head-End Network Controller. The ICE-HE Ethernet Head End manages iC-Net communication over RF Coax to ICC1 (1-way) and ICC2 (2-Way) TV Controllers. Each TV Controller is assigned a unique device number from 1 to 4000 to which control commands are addressed. The devices are organized into 16 zones of 255 devices.
Writing Your Own Control Code While most IC systems use our Display Express software to control displays, a growing number of integrator are writing their own control applications, using AMX, Crestron, RTI, or other platforms. We encourage creative solutions, and are happy to support those who take advantage of our protocol. From our history of support activity, we are providing a few tips to help you on your way.

To simplify controlling groups of devices, iC-Net is divided into 15 Zones of 255 devices. All the devices within each zone can be controlled simultaneously by sending a command to a single virtual device number. For example, noting the zone chart below, if we send a Power On command to device #256, any TV controller numbered between 257 and 511 will instantly turn on. If we send a Power Off command to device #4095, all devices in the system will turn off.
One of the key tasks for iC-Net integrators is to create a logical System Map, assigning device numbers to TV controllers so they fall into logical zones. The device mapping could be sorted by type or location; whichever suits the application.
The diagram below shows the structure of a typical Contemporary Research media retrieval system. One of the key aspects for iCC-Net communication is to provide a forward and return (sub-channel) path for data if you’re using ICC2 2-way TV Controllers.
Read before operating equipment. 1. Cleaning - Unplug this product from the wall outlet before cleaning. Do not use liquid cleaners or aerosol cleaners. Use a damp cloth for cleaning. 2. Power Sources - Use supplied or equivalent UL/CSA approved low voltage DC plug-in transformer. 3. Outdoor Antenna Grounding - If you connect an outside antenna or cable system to the product, be sure the antenna or cable system is grounded so as to provide some protection against voltage surges and built-up static charges.
