Older version had separate infra red diode and infra red sensor, instead of opto-coupler IC. The separate components usually had some kind of cover over them to prevent light from affecting the function of those components. The cover was either a rubber dome, or heat-shrink tubing.
LED OPERATION
The top LED is DMX input status. Solid ON is Receiving Data. Blinking is Invalid Data or No Data
The bottom LED is +5V and should be solid on
TROUBLESHOOTING
Channels 20-24 all turn on together
RP2 is likely cracked in half or failed. OpAmps could also have failed
Outputs are flickering
C4 is probably failing
No output on normal, but works fine with self-test
DIP switches are probably not set correctly. Be sure DIP switch 3 is down
If DIP switches are correct, possibly a bad DMX chip or DMX opto-isolator
U2 is DMX chip, U22 is opto-isolator. There are no spare internal DMX chips
DMX Status LED is solid on regardless of DMX being plugged in or not
C4 failing. Outputs are also very likely flickering
