Hi,

We are using RS232.  Using the XFlash unit as configured through spec does not show the same delay as the IOC.  Disabling the Temperature monitoring PV (:ReadTemperature) which is on a 1s scan-rate, seems to alleviate the problem a bit.

Thanks,

Hi, Phil.

Over what physical link are you communicating with the XFlash?  If it's
RS-232, it could just take that long to transmit the data over the slow
link.
