1 Card OK.
This pin essentially follows the card’s status LED: When the LED is green, the pin
will indicate card OK. The pin will indicate NOT OK when the LED is yellow, that is
when the FPGA is being loaded.
2 Input 1 present Output 1 present
3 Input 2 present Output 2 present
4 Input 3 present Output 3 present
5 Input 4 present Output 4 present
6 Input 5 present Output 5 present
7 Output OK.
This pin follows the output LED: It will
indicate OK when the output LED is
green, which is when output is present
and the laser not faulty.
Input OK.
This pin follows the LOS LED: It will
indicate OK when the LOS LED is
green, which is when input is present
and taken from the main input.
8 Ground (GND)
Table 5: GPI pin-out
The polarity of the GPI pins is such that OK/present is indicated by a leading transistor
connection to ground. Conversely, an error is indicated by high impedance to ground.
7.3 The main board
There are also a number of connectors on the board itself. None of these are intended for
the end-user.
