3.2 FRONT
PANEL
INDICATIONS
3.2.1 REM
The REM LED indicates that the PCB is being accessed by the Rack Controller. It is NOT an
indication that the unit is in REMOTE control mode. As the Rack Controller accesses the module
the LED will emit short blips.
3.2.2 +V
This LED indicates that the on board 5V regulator is operating. It does not show that the unit is
receiving the distributed rack power. For example if the on board fuse is ‘blown’ the LED will not be
ON.
3.2.3 OPERATING STANDARDS
This group of green LEDs indicate the presence and operating standard of both channels. If one of
the channels has no input then none of the four LEDs for that channel will be ON. If a signal is
present then one and only one of the four LEDs for that channel will be ON.
If NTSC is being used then there is no front panel indication whether it is standard NTSC or the
Japanese variant, which has no setup.
3.2.4 TEST SIGNAL
The normal Test Signal available is PLUGE, and this is used in all other parts of this manual. It is
possible that future variants may use different test signals, so the front panel has been designed
with this in mind.
This switch is used to select PLUGE when the unit is in LOCAL control. There are some restrictions
on the use of PLUGE as described in section 3.7.
When selected PLUGE only appears on the CVBS (or YC) outputs. Its selection does not affect the
SDI output which will continue to reflect the SDI input.
The LED indicates that PLUGE is on at least one of the outputs. This is not necessarily enabled
from the front panel switch, since it can have been set over DART or from the GPI.
3.2.5 REM/LOC
This switch is used to select control from LOCAL to REMOTE over the DART control network.
Local control is made using the internal DIL switches and the front panel PLUGE switch. All
equivalent functions are available over DART.
