[time-nuts] Prologix VRBOOT error

[Prologix]

Hello Matt,

It appears your Prologix GPIB-USB controller is in firmware update mode.
Please follow these steps:

1. Disconnect USB cable and GPIB cable. If the controller is plugged onto an
instrument, unplug it.
2. Connect USB cable.
3. Connect GPIB cable, or plug onto instrument.

Let me know if you have more questions.

Regards,
Abdul

Subject: [time-nuts] Prologix VRBOOT error

I just received a Prologix GPIB interface today.  At first it was
working, but it only works some times when it is connected.  The
others it sends the following to minicom:

    "?????????????????VRBOOT???????????"

It seems to get commands and try to respond, but it sends weird
things.  If I send a "++help" it sends S and more question marks.
Pressing enter causes it to send more question marks.  Powering off
and back on doesn't help.

Anybody seen this behavior before?

Matt
