4.2 Remote Control
The hand held IR remote control enables the user to access many of the functions of the TView Pro AV 1600. Since
the IR unit is intended to be used in presentation situations, certain functions of the TView Pro AV1600 may only be
accessed via the Front Panel or via RS-232/422. This prevents the accidental use of some controls (i. e. switching
from NTSC to PAL inadvertently in a presentation; a presentation disaster!) and keeps the interface simple. The
Remote Control interface is indicated in Figure 3. The Remote Control is a line of sight device; the IR receiver is
mounted inside the TView Pro AV 1600 next to the LED displays. The Remote Control will only operated when it is
within the line of sight of the LEDs of the TView Pro AV 1600. The maximum range is about 25 feet.
Several controls are available from the IR unit. Flicker Filter, UnderScan/Overscan, Freeze Frame, Auto Reset and
Horizontal and Vertical Size, Position and Zoom. Of these, the first three controls (Flicker Filter, Underscan and
Freeze Frame) are simple toggle switches that activate or de-activate the indicated function. Auto Reset performs a
Reset to a known state (see section 4.2.2 below). Horizontal/Vertical Size, Position and Zoom cycles the function of
the Directional button between Size, Position and Zoom Position. Depending on the state of the Size, Position and
Zoom switch, the Directional Control will influence either the size, position or zoomed position of the converter
output. In all cases, the currently operating function will be indicated on the LED display of the TView Pro AV 1600.
4.2.1 Auto Reset with the Remote Control
The Remote Control unit will return the TView Pro AV1600 to a known state (as indicated in section 4.1.2 above). The
Auto Reset button on the Remote Control is the large button indicated in figure 4.
4.3 RS-232/422 Control
All of the functions detailed in section 3.1 are available from RS-232/422 control. Every TView Pro AV 1600 is
operable in both RS-232 and RS-422, but must be correctly set up for each standard. When configured for RS-422,
up to 8 TView Pro AV 1600s may be connected in a single RS-422 wired system. The TView Pro AV 1600s will react
to controls that are delivered to a unique address that is programmed into each TView Pro AV via the Front Panel
control.
When configured for RS-232, only a single TView Pro AV 1600 may be attached to the RS-232 link. The default
configuration is RS-232. You must program an address for a Pro AV 1600 connected with the RS-232, even though
only one unit may be connected in an RS-232 configuration.
