I have a working Z3801A, it has had an AC Supply added to it and the RS422 port has been reconfigured to RS232. I downloaded and installed Z38XX, configured both the Port and Device to the recommended parameters: Data Rate: 19,200 Parity: Odd Data Bits: 7 All I can get, looking at the Device Window is: Send *IDN ? Received Detected Device Undefined I am assuming the Z801A and the Computer are not talking to each other, but I am at a loss as to what to do next. I tried a different (known working) RS232 to USB adapter and get the same results. Any ides what I can do next ? Thanks, Dick, W1KSZ Sent from Outlook<http://aka.ms/weboutlook>

Hi Standard generic drill: 1) Swap RX and TX (or check with a voltmeter) 2) Cycle through the normal set of baud rates 3) Double check the jumpers on the 422 to 232 conversion 4) Check with a terminal program, typing in the *IDN? query by hand Yes it’s sort of a mix and match of what’s above. The order is purely a “what I usually mess up” sequence.

>From what I recall, the manual was accurate on the baud, stop bits, parity, etc. Just a few thoughts.... Make sure that the serial port is working as expected... Do a loop back test if possible. Are you using a USB to Serial adapter? Many of them have some weird quirks. IMHO, FTDI based adapters work better than others. Forego using the Z38XX. Try using a plain terminal app and see if you get any weird characters echo'd back instead of expected responses. Etc... There are a lot of possible causes when a serial connection isn't working right.

Hi The gotcha is that the 3801 is an “ask for it / get it” protocol. If you don’t get the query formatted correctly, there will be no data coming back. It’s not like some other GPSDO’s that just yack all the time.

Connect to a terminal emulator and IDQ it you will either see garbage in which case serial config is wrong and you need to try a new set of values Or using a breakout box connect a scope to the txd and rxd lines and compare pulse widths Content by Scott Typos by Siri > On Sep 16, 2017, at 4:22 PM, Bob kb8tq <kb8tq@n1k.org> wrote: > > Hi > > The gotcha is that the 3801 is an “ask for it / get it” protocol.

I have a better idea ... anyone want a Z3801A ? I'll swap it for a late model, working Trimble T-Bolt.

You need the null modem adapter which reverses the TX and RX lines on one end of the cable. Also not all USB to Serial adapters work.. I bought an old laptop with a real serial port  at a junk computer shop for not much more than USB adapter to solve the RS-232 problem Dave On 9/16/2017 6:48 PM, Scott McGrath wrote: > Connect to a terminal emulator and IDQ it you will either see garbage in which case serial config is wrong and you need to try a new set of values > > Or using a breakout box connect a scope to the txd and rxd lines and compare pulse widths > > Content by Scott > Typos by Siri > >> On Sep 16, 2017, at 4:22 PM, Bob kb8tq <kb8tq@n1k.org> wrote: >> >> Hi >> >> The gotcha is that the 3801 is an “ask for it / get it” protocol.
