12 8950DAC 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 .
Table 3 on page 13 provides the possible output conditions and LED states
that result from different configuration and input conditions.
Table 2. Indicator LEDs and Conditions Indicated
LED Indication Condition
Fault
(red)
Off Normal operation
On continuously Module has detected internal fault
Short flash
EDH errors will cause short flashes. In most applications a few, infrequent EDH
errors will not be of consequence. Continuous EDH errors result in obvious output
signal degradation.
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
(yellow)
Off Input signal is 625 standard (Auto-select active) or no signal is present
On continuously Input signal is 525 standard
Flashing Input signal is 625 standard and mode select is in manual position
MAN
(yellow)
On Input is forced by configuration to accept one format, either 525 or 625
Off Module will detect and accept either input signal format
625
(yellow)
Off Input signal is 525 standard (Auto-select active) or no signal is present
On continuously Input signal is 625 standard
Flashing Input signal is 525 standard and mode select is in manual position
VID PRES
(green)
Off No valid input signal is present 1
1 If no valid video signal is present, all four analog outputs will be 0.0 VDC with some occasional low level noise.
On A valid video input signal is present
2ND
(yellow)
On Second bank of setup functions is accessed by the rotary switch
Off First bank of setup functions is accessed by the rotary switch
