IDX 12 not appearing to send pulses to Dix LED 6- taking tokens /coins and giving no time to customers.

One of my IDX 12 units is all of sudden not sending pulses to my DIX LED 6. The quarters and tokens a going down into vault the green led is flasing or pulsing 4 times for my $1 tokens and 1 time for a quarter. . Zero or no time on display to my customers.
The crypto pay swip and tap are working well and doing standard operations. LED 6 seems solid
I replaced the 12 with another unit I had as a back up and doing same thing.
IDX is no more, what about a wiring diagram for IDX 12. Anyone have one? Like tomake sure what is coin pules output or color is.
Any suggestions would be appreciated, who do you guys like for coin acceptors these days?

Have you checked the connections from the IDX 12 to the LED 6? I am not familiar with the IDX12, but the below shows the wiring and colors for IDX to LED 6 timer
