[time-nuts] FE-5860A - R232 working but S type commands don't work.

[Mark C. Stephens]

I finally got around to testing a couple of FE5860 I bought on eBay 19 months ago for $30.00 a piece including shipping.

I have PPS, !0Mhz, lock indication all connected and working.

Rs232 appears to be working as this command appears to have had a chat with the rubidium:

However programs such as FE5680A that use the 'S' type commands don't seem to work.

I am pretty happy with them but one is off by 0.1E-6 Hz. Ideally I'd like to trim it back closer to 10 MHz using rs232.

Any hints graciously received with thanks :)
