A brief report about the new front end machine "C1ISCEX" installed on the X end (old Y end).

Still the DAC is not working.

- Timing card

It's working correctly.

The 1PPS clock signal is supplied by the vertex clock distributer via a 40m long fiber.

- ADC

All 16 channels are working well.

We can see the signals in the medm screen while injecting some signals to the ADC by using a function generator.

-DAC

All 16 channels do NOT work.

We can not see any signals at the DAC SCSI cable while digitally injecting a signal on the medm screen.
