Problem Possible Causes and Remedies
Power switch does not
illuminate in the
ON
state
Loose power cable: Verify that the power cable is fully inserted into the unit’s
power connector and that the power supply’s connector collar is properly
threaded onto the
ScaleOR ’s power connector.
Defective power supply: Replace the power supply.
Wall socket: Some wall sockets have on / off switches built in. If the socket you
are using has a built in switch, verify that is in the on position.
Mitigation:
Bypass the
ScaleOR by connecting the output of the video source directly to a
monitor.
Confidence test Turn the ScaleOR off, then connect its DVI output port to a powered up
monitor. Turn the ScaleOR on, the NDS logo should appear on the monitor
approximately 10 seconds after the ScaleOR is turned on. Turn the ScaleOR off,
then connect its SDI output port to the monitor and repeat the test. If your
ScaleOR has a Fiber Optic output, turn the ScaleOR off, then connect its fiber
Optic output port to the monitor and repeat the test.
Video is not displayed If the ScaleOR ’s power button’s blue ring is flashing once per second, then the
unit is not detecting a video signal. Verify that an input signal is connected to
the unit’s input. If there is a connection try replacing the video cable. If video
appears, then the cable is bad. If video does not appear, then connect the unit
to a different video source. If video appears, then the previous video source is
turned off, or defective. If video still does not appear, then the
ScaleOR ’s Input
module may be defective, or not properly seated. Try reseating the input
module. If that doesn’t clear the problem then the input module is defective.
If you determine that the input module is defective, please contact customer
service for assistance.
Mitigation:
If possible, connect the video source directly to the video display.
Video is not displayed
from a given output port Verify that video is displayed from the DVI or SDI output port. If video from the
DVI port is displayed, and not from the SDI port then ScaleOR ’s output mode
may set to a DVI only mode (see Output Modes Table on page 15), the cable
connecting the SDI port to a monitor may be bad or the SDI output is defective.
If video from the SDI port is displayed, and not from the DVI port then the cable
from the DVI port may be bad, or the DVI port is defective.
If you determine that one of the output ports is defective, please contact
customer service for assistance.
External control failure USB cable is loose or defective: Verify that the USB cable is fully inserted into the
ScaleOR ’s USB port and the PC’s USB port.
Control program has failed: Restart the program
Controlling PC has failed: Restart the PC
Mitigation:
Control the
ScaleOR from its front panel Keypad
