Let's go:

- Do they talk to a PC or other device with a crystal controlled
oscillator or to other units the same?
They talk to a PC at 4800bps and some of them talk to a 12F629 running
on a internal RC too.

- What temperature range are they used over?
Ambient temparature.

- Where are they used? (in an office / lab outdoors / industry etc).
Everywhere

- Are they all from the same batch or from different batches?
Different batches.

I hope this helps.

That's impressive on an RC clock - especially if they are used at both
ends of the link. That's a good testimony to the stability of the RC
clock.

If you don't mind telling:

- Do they talk to a PC or other device with a crystal controlled
oscillator or to other units the same?

- What temperature range are they used over?

- Where are they used? (in an office / lab outdoors / industry etc).

- Are they all from the same batch or from different batches?
