Medium or Full Mode
Table 2
shows the operating modes of an extender in medium or full mode (EDT firmware rev. 11 or higher)
.
NOTE
This table is for the fiberoptic extender only, as the coaxial extender is available for base mode only.
For full-mode cameras, which typically operate at 60 to 80 MHz, configuration codes of 1-4 (camera end)
and 2-4 (framegrabber end) should work. For full-mode cameras that transfer 80 bits per clock cycle, use
configuration codes of 1-5 (camera end) and 2-5 (framegrabber end).
For medium-mode cameras, which typically operate at 40 MHz, configuration codes of 1-1 (camera end)
and 2-1 (framegrabber end) should work.
For instructions on verifying and updating the firmware, see
Firmware on page 12
.
Resetting or Changing the Operating Mode
Your extender is factory-preset for the operating mode that was specified in the product order. However, if
you need to reset or change the operating mode, you can do so by setting the LED configuration code.
NOTE
If you change the operating mode, be sure to relabel the extender to prevent future confusion.
To reset or change the operating mode (configuration code):
1.
Turn off the power to the extender, and disconnect the extender from everything except a power supply.
NOTE
EDT recommends connecting the power supply to a power strip or some other device that allows easy
access to both the power and the extender at the same time. This is because, as you follow the steps
below, it may become necessary to turn off the power and restart the process (see
step 4
).
2.
Press the recessed button on the bottom of the extender with a fine, blunt point – such as the tip of a
ballpoint pen – as in
Figure 6
