Status and LED Status Codes
As previously discussed, at power-on the LED blinks the extender’s configuration code one time, and then
blinks rapidly as the firmware loads. After power-on, the LED continuously displays the extender’s status
code, which indicates whether the unit is working properly or has errors (see
Table 3
).
Table 3. LED status codes
If LED shows... It means...
Steady light
All OK – everything is working properly.
Slow blinks
(1Hz)
There is an error from the other end. The typical causes are:
• The extender at the other end has no power, or its operating mode does not match the operating
mode on this extender (see
Configuration and LED Configuration Codes on page 7
).
• The cable connection is compromised, either by incorrect or damaged cabling, or by moisture or
debris in the extender’s cable connectors (see
Care and Cautions on page 1
).
Fast blinks
(10Hz)
There is an error from the camera to the extender, related to the camera’s pixel clock.
If the fast blink is on the camera-end extender: either the camera has no power, or the operating
mode on the extender does not match the operating mode on the camera (see
Configuration and
LED Configuration Codes on page 7
).
If the fast blink is on the framegrabber-end extender: either the extender or the resync cable is faulty.
Both slow and
fast blinks
There is at least one slow-blink error and at least one fast-blink error.
2 fast + 2 slow +
2 fast blinks
The extender is configured with an unsupported operating mode (see
Configuration and LED
Configuration Codes on page 7
).
No light
The extender has no power or is faulty.
