3. Still keeping the button pressed, turn the power back on, perhaps using the switch on a power
strip. The green LED turns on, then turns off when the button is released.
NOTE
If pressed longer than two seconds, the LED blinks a series of diagnostic blinks. If this occurs, turn
the power off again and then restart the procedure.

4. Press and hold the button. The LED blinks slowly.
5. Release the button after the LED has blinked the correct number of times for the first digit of the
required blink code, as specified in
Table 1
. For example, if you want to set the mode to 2-3, wait
for the LED to blink twice before releasing the button.
6. Press the button again and release it after the LED has blinked the correct number of times for the
second digit of the required blink code. For example, if you want to set the mode to 2-3, wait for
the LED to blink three times before releasing the button.
The RCX C-Link saves your selection into flash memory immediately after you enter the second
digit of the code. The LED now blinks in the pattern selected.
NOTE
If the LED blinks the error blink code of two fast, two slow, and two fast, an error has occurred and
the code has not been saved to memory.
7. Cycle power to the module without pressing the button.
When the RCX C-Link is powered up without the button pressed, the LED flashes the current code
once, then show its status (see
Using the RCX C-Link in Base Mode on page 2
).
NOTE
If you enter an unsupported code, the LED blinks two short blinks, two long blinks, then two short
blinks.
Backward Compatibility
Most RCX C-Links with firmware revisions earilier than revision 11 support only cameras with speeds
of 20–40 MHz at 1.25 GBaud using blink codes 1-1 (ignore Data-Valid), 1-2 (use Data-Valid), and 2-1
(frame-grabber end). (Some were shipped with special firmware to support other types of cameras.)
For backward compatibility, firmware of revision 11 or later, as described in
Table 1
, behaves
identically for blink codes 1-1 and 1-2. As of revision 11, Data-Valid is automatically detected.
Also, customers using blink code 2-2 at the frame-grabber end for 16-bit mode can use the
corresponding blink code of 1-2 at the camera end.
If blink code 3-5 (not shown in
Table 1
) does not produce the error blink for an unsupported blink code
(two fast, two slow, two fast), then you have firmware of revision 11 or later.
