The Difference Between the 232-ATSC+ and ICC2-ATSC+ Tuners

Physically, they look alike, as both have an RS-232 connector in the back – the difference is in how it is used. Also, the ICC2-ATSC+ has 3 RF “F” connectors on the back, as highlighted below.

Designed for typical system integration, the 232-ATSC+ links with a control system via its RS-232 port.

Designed for through-the-RF Display Express applications, the ICC2-ATSC+ uses the RS-232 port on the back to control the display or projector it is connected to (turns it on and off, and selects inputs). System control commands are received via the RF coax, receiving a data channel sent from our ICE-HE Head End. As with the other ATSC+, the tuner changes channels and volume levels, but its RS-232 port manages the monitor or projector. That’s why we will call to verify the make and model  of display, so we can load the right control commands into the tuner. If the client already has an ICC2-ATSC or ICC2-ATSC+ tuners, we can determine the control programming by looking up the existing tuners’ serial number.

For those who install the ICC2-ATSC+, note that you need to connect the RF feed to the RF In at the top of the tuner, then wire the included short RF cable from RF Out at the top, down to the Air/Cable input below. The first loop-through picks up the control channel, and the second loop passes the TV channels to the tuner.
