The 232-ATSC HDTV Tuner is an integrator-friendly universal HDTV tuner, controllable via two-way RS-232 and discrete IR commands. Able to fit two-across in a 2RU rack space, the compact tuner outputs HDMI, RGB/Component, and composite video simultaneously. NTSC broadcasts are upscaled for HD display. Digital audio is available from HDMI, coax, and optical connections, as well as variable-level stereo audio.
Physical Size (HWD): 8.5” [216mm] wide x 2.43” [62mm] height (2RU) x 8.0” [203mm] deep Weight: 2.
Tuning Frequency Range: ATSC and Clear QAM (cable) television 55.25 to 801.
DIGITAL TUNING OF CABLE Channels Symptom: Channel ID is in XX-XX form, not cable box Guide form Cable boxes translate the actual channel #s into a virtual Channel Guide, using channels 2 – 900, or more. The actual (physical) channels have IDs in XXX-XX form, just like off-air channels. Noncable HDTV tuners like the ATSC or LCD TVs don‟t provide Guide features, so the channels will be displayed in their native, physical major-minor channel form.
HDMI Symptom: No Video or Signal Most monitors accept HDMI in the RGB and Component color space, but there are exceptions. Try switching from RGB to Component (Front panel mode 48). Switch between 720p and 1080i, or down to 480P or 480i for old DVI sets. (Front panel mode 49) If you‟re connecting via a Cat5 interface, HDMI receiver, or switcher, some delay the HDCP signal slightly out of range. Call CR Support on how to extend the delay on HDMI.
To Enter a Front Panel Programming Mode: 1. Press and hold the Power button, then press the Volume Up button. 2. Release all buttons, the 232-ATSC will now be in the front-panel programming mode. The Air LED will flash, indicating programming mode. 3. The first two digits show the mode, the second show the option. 4. Changes are saved in non-volatile memory as they are entered. 5. The Volume up/down buttons scroll through programming modes, forward and reverse. 6.
The HD2-RC IR Remote included with the 232-ATSC can be used to setup the tuner and for daily operation. All of the functions on the remote have equivalent commands in RS-232, Ethernet, and Wired IR formats. In addition, the 232-ATSC front panel buttons can perform Power, Channel, and Volume control. Power Turns tuner on and off. Discrete on and off IR commands are available as well. Volume Control Use the Vol+, Vol- and Mute buttons.
