12 8950ADC Instruction Manual
Power Up
A red FAULT LED indicates an error situation and, with the previously
described LEDs, can indicate the operational conditions presented in
Table 2 . The table describes signal output and LED indications for various
input/reference combinations and user settings.
Table 2. Indicator LEDs and Conditions Indicated
LED Indication Condition
FAULT
(red)
Off Normal operation.
On continuously Module has detected a CPU problem or FPGA programming problem.
Flashing Configuration problems. Check inputs and settings.
COMM
(yellow)
Off No activity on frame communication bus.
Long flash Location Command received by the module from a remote control system.
Short flash Activity present on the frame communication bus.
CONF
(yellow)
Off Module is in normal operating mode.
On continuously Module is initializing, changing operating modes or updating firmware.
Flashing
Indicates rate of change of toggle switch controlled analog setting. The longer the
switch is held, the more the flashing rate and the change-of-setting rate increases.
PWR
(green)
Off No power to module or module’s DC/DC converter failed.
On continuously Normal operation, module is powered.
525 1
(yellow)
1 In Auto mode, this LED changes status depending on input signal.
Off No input signal is present, or 625 input is present.
On continuously Input signal is 525 standard.
Flashing 525 standard input signal is manually selected, but actual signal is 625 standard.
MAN MODE
(yellow)
Off Module will automatically detect and accept either input signal format.
On Input is forced by configuration to accept one format, either 525 or 625.
625 1
(yellow)
Off No input signal is present, or 525 input is present.
On continuously Input signal is 625 standard.
Flashing 625 standard input signal is manually selected, but actual signal is 525 standard.
VID PRES
(green)
Off No valid input signal is present.
On
A video input signal is present and there is valid composite sync on the Y/G channel
or reference input.
2ND
(yellow)
Off First bank of rotary switch selected.
On Second bank of rotary switch selected.
