ICC1-TC Tuner/Controller Product Manual 082020
Integrated Display Controller
The ICC1-TC supports sending control commands to the connected display using RS-232 or HDMI CEC. The power state of the display will
follow the power state of the ICC1-TC.
When used as part of an iCC-Net control system, additional display control functions are available. For RS-232 controlled displays, the
control functions include power, source selection, and the ability to pass through custom RS-232 strings from the control system.
Display control will need to be enabled in the on-screen text System menu or via RS-232 command. The options are HDMI CEC or RS-232. If
RS-232 is selected, the RS-232 port will only function as transmit only to control the display.
The RS-232 protocols for many common TV and display makes and models are built in to the ICC1-TC application firmware. If a desired
display type is not listed, contact Contemporary Research support for assistance.
HDMI CEC Control
HDMI CEC may be selected for sending power commands to the display. No other control functions are available for CEC control. HDMI CEC
sends standardized control commands over the HDMI cable. CEC functionality is available in many TVs and
displays designed for the
consumer market. If control of the TV or display via HDMI CEC is desired, it is important to check the TV or display’s documentation to
determine if CEC is supported.
It is common for manufacturers to use their own unique term to refer to HDMI CEC. For example, Samsung refers to CEC as Anylink. LG
refers to it as SimpLink.
CEC will likely need to be enabled in the display. Some displays will automatically detect that a CEC supported device has been connected
and prompt for confirmation.
Although the industry strives for standardization relating to CEC, it is possible that some or all CEC control communication between the
ICC1-TC and connected display may not function depending on display make and model. In this situation, RS-232 is recommended for
reliable display control.
RS-232 Display Control
One-way RS-232 display control is available through the rear panel DB-9 RS-232 port. The RS-232 port may be used to send commands for
power and input source selection. When used with Display Express or a third-party control system using iCC-Net protocols, it is possible to
forward custom RS-232 strings to the display.
The connection to the display should be with an RS-232 null modem cable. Most displays with a 3.5mm RS-232 port are compatible with the
optional Contemporary Research CC-COM 3.5 (5061-009) serial cable. Typically, displays from LG with a 3.5mm RS-232 port require a DB-9
male to female null modem adaptor (5061-012) if used with the CC-COM 3.5 serial cable or equivalent.
The RS-232 display (TV) type will need to be selected via the on-screen text menu or RS-232 command. Refer to the table for a list of the
supported display types. If the desired display type is not listed, contact Contemporary Research support for assistance. The com port
parameters will automatically be changed to match the requirements of the selected display type unless otherwise noted.
