Hello, we have been using Rigaku ultima IV diffractometer in our lab for several years. Every now and then we come across communication problems with PC and instruments. And the service people changed instruments mother board once, PCle boards three times which costs a lot.

We have the same problem again. The XG property shows cannot generate x-rays, check generator. We have tried trouble shooting the the serial ports also.

Please help me diagnose and solve this problem. (Also how do I approach if the problem is board cannot be to communicate with chiller, which we cannot not see in pc)
