Power
The power LED, marked +V, indicates that the 5V VCC power rail is present on the board. This shows not
only that power has been applied to the rear, but also that the on board regulator is functioning.
There is a fuse on the unit in series with the power input, and if this has 'blown' then the +V LED will be OFF.

Remote Control
The V1633A can be controlled from either the front panel, shown above or through the DART remote control
network. If DART is used then any DART controller, with knowledge of the V1633A can be used. Vistek can
provide either the V1605 1U control panel or VIEWFIND, which is a PC based universal control system. Any
DART controller can be used, provided it has 'knowledge' on the V1633A.
The control source, Local or Remote, is selected by the toggle switch on the front panel. The REM LED
does not indicate the selection of remote control, but 'blips' to show access by the Rack Controller, if fitted.
Only the position of the toggle switch indicates that remote control has been selected.
The status LEDs on the front panel are active for Local or Remote control so always show the operating
condition.
