I’m having an issue where counter 0 of my USBCTR08 is not registering counts when I attempt to do a basic scaler count sequence with the MEDM (count time 1s, count preset 1000000). I have TMR0 set at 1 MHz connected to my counter 0 input and my counter 0 output connected to the gate. I can complete a count sequence by using the preset counters on counters 1-7 connected to TMR0 but not c0. I’ve verified my TMR0 signal with an oscope, the numbers and timing on the other preset counters makes sense, and this same hardware setup works at our beamlines that use the USBCTR with SPEC, so I’m fairly confident in the hardware and signal patching. Version info: scaler 4.0, measComp R4.1, and epics 7.0.7.
