Status, Configuration, Operating Mode
Each extender has a light-emitting diode (LED), as in
. By displaying various patterns of blinks, the LED
communicates information about the extender’s configuration and status, as follows.
•
At power-on, the LED blinks a one-time
configuration code
to indicate the operating mode for which the extender
is configured, and then blinks rapidly as the firmware loads.
•
After power-on, the LED continuously displays a
status code
which shows steady green if the unit is working prop-
erly, or shows a different blink pattern if there is an error.
This section explains the status and configuration codes, as well as the related operating modes.
Status
As stated above, at power-on the LED will blink the extender’s configuration code one time, Then it will blink quickly
while 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
Configuration
Each extender is preset and prelabeled for the operating mode you specified in your product order. The operating mode
is selected and indicated through a blink pattern, displayed once at power-on, called the LED configuration (blink) code.
The LED configuration code consists of two digits, each represented by a certain number of blinks. The two digits are
separated by a pause, shown in this guide as a hyphen. For example, a configuration code of “one blink, pause, one
blink” is shown in this guide as 1-1.
A first digit of 1 means the unit is configured for the camera end; a first digit of 2 indicates that the unit is configured for
the framegrabber end. The second digit must be the same for both ends (camera and framegrabber). With an EDT FOX
framegrabber, there is no extender at the framegrabber end, so the configuration code is set at the camera end only.
For a typical base-mode system, a configuration code of 1-1 at the camera end and 2-1 at the framegrabber end permits
standard base-mode operation at clock frequencies of 20–40 MHz.

LED behavior
Significance
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
).
• The cable connection is compromised, either by incorrect or damaged cabling, or by moisture or debris in the
extender’s cable connectors (see
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
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
).
No light
The extender has no power or is faulty.
