The new auto-scan capability of the 232-STSi allows the user to search for channel frequencies, select a TV standard, and save as a numbered channel Preset that includes the frequency and TV standard. Using this feature, channel Presets can include broadcasts from neighboring countries with different audio standards. Scanning and adding channel presets can be performed via RS-232 commands, Tuner Helper software, and the optional IC-RC IR wireless remote.
Overview The 232-STSi full duplex RS-232 scheme enables a system programmer to control all TV Tuner functions as well as monitor 3 groups of TV Tuner status. All commands are sent as ASCII strings. No delays between characters or commands are required, as data is interrupt driven and buffered. The 3 status groups are: Channel/Source Select, Audio Levels/Mode and Front Panel.
General Commands Q0= Caption Mode Off (0-2) Sets captioning mode 0=Captioning off (default) 1=Captioning on 2=Captioning active when volume is muted Q1= Q2= Example: „>Q0=0‟ or „>Q00‟ Captioning off Captioning Type (1-8) Turns on captioning type Video Loss Detection (0-3) 1=Caption 1 (normal setting for most captioning) 2=Caption 2 3=Caption 3 4=Caption 4 5-8= Text 1-4 (rarely used) Selects response when a loss of video signal is detected 0=Both audio and video muted (default-blue screen for video

RS-232 Control Character Generator Commands The optional character generator supports an on-screen display that is 32 columns (characters) across by 13 rows (lines) down. An imaginary cursor represents the current screen write position. Writing text automatically increments the cursor to the next character space. The character text is always white. TM=
RS-232 Control Keypad Channel Command If you‟re using an external control system, this command will emulate the pressing of numeric keypad buttons for channel selection, which means you won‟t need to use extra elements for capturing channel commands in your programming. The KC command will access any channel, KT will only access a channel stored in the Tune Ring. KC=0 KC=1 KC=9 KC KT=9 KT KD Emulates „0‟ key, accesses any channel. Emulates „1‟ key, accesses any channel.

Typical: [Attention] [Unit#] [data ...data] [cr] [lf] 232-STSi status response strings contain ASCII characters similar to those used for the same functions in command strings. An ASCII 'carriage return' and „line feed' follow each response string. Functions shown as N/A are not applicable; characters will appear in status strings as lower-case x.
