I've seen several posts related to Waters EPC problems, mostly caused by wrong system configurations.

Has anybody seen EPC problem as below:

"0x7bb56c0 (STAT_RBS): epcasDataReady(): Data not ready ... timed out waiting for nPeriphRequest to go low (Retries = 201)

0x7bb56c0 (STAT_RBS): epcasReadAddress: timed-out waiting for DSR nPeriphRequest bit to go low ... DATA NOT READY TO COME BACK

0x7bb56c0 (STAT_RBS): ecpOpenReverse(): failed to set port into reverse mode (DSR = 0xff)

0x7bb56c0 (STAT_RBS): epcasReadAddress: timed-out waiting for data in FIFO: nReadCount = 4000"

I appreciate any comments from anyone familiar with LCT Premier Mass Spec.
