Re: [time-nuts] Conversion of Stanford PRS10 to RS-232 Communication

Many thanks for the steer.  I was getting hung up on the reference to
jumpers.  I'll order the 240R and 3K9 SMD resistors (per the Rev H parts
list) and see how it goes.

The word jumper may be misleading. Soldering/de-solderig of components required.
In Appendix 19, "Configuration notes » there is an explanation of how to alter 
the function of pins 4,5,7.

Does anyone know how the format can be changed?

The manual doesn't say anything more than there are jumpers inside that
can be changed.

Page 20 of the manual has the details...

[time-nuts] Conversion of Stanford PRS10 to RS-232 Communication

[Philip Jackson]

I understand that the PRS10 Rubidium units either talk to the host
device via a RS-232 serial command language or via analog values using
the same set of pins in both cases.

The manual says that internal jumpers can be used to switch between
communication modes.

I have a PRS10 that is set for analog working and would like to switch
it over to RS-232 mode.

A cursory peek inside the case with no disassembly doesn't reveal any
simple jumpers/headers that might be used to flip formats.

Does anyone know how the format can be changed?

The manual doesn't say anything more than there are jumpers inside that
can be changed.

Many thanks

Philip
