If the scan converter does not respond to controls
Symptoms Solutions
The picture does not
move on screen when the
horizontal and vertical
centering controls are
rotated. The VSC may be set for executive mode.
Adjustments can be made via RS-232
control, or exceutive mode can be disabled
by simultaneously pressing the Next and
Size buttons for 2 seconds.
The VSC responds to
adjustments made via the
front panel, but not to
selections from the IR
remote control. Signals from the IR remote control may
not be reaching the VSC. Change the
placement of the scan converter so that the
IR signals have a clear transmission path
between the remote control and the VSC.
There is no response to
commands from the
RS-232 controller. Ensure that the baud rate (9600 baud) and
communication protocol are set correctly.
