< The 232-ATSC 4K channel status is split into Major Channel and Minor Channel sections. The Minor Channel will always be 000 for analog channels. The Minor Channel status will display “F00” if the Major channel is a special “one-part” digital channel. Also, as one-part channels can go higher than 999, the Minor status will indicate how many thousands (up to 63) should be added to the Major number.

Volume 1 emulates legacy 232-series volume level for compatibility with existing applications. Volume 2 shows actual 232-ATSC 4K level, from 0-100. Audio status will be sent automatically following a volume toggle command from front panel control, IR remote, or RS-232- command.
Set the first unit in the RS-232 chain to the highest Unit#, then wire in sequence to the last tuner in the chain. Contemporary Research tuners use an intelligent data bus in which the tuner with the highest Unit # receives all commands then passes through commands to tuners with lower unit numbers.
The 232-ATSC 4K will respond to ICC-Net protocol command strings sent from an ICE-HE-DXL, IP-DXL, Display Express Server, or third-party control system processor. The 232-ATSC 4K is compatible with iCC-Net commands sent via Ethernet. The unit is not compatible with iCC-Net commands sent over the RF coax network.
