Series2 act like series1?

I have series 1 modules talking in transparent mode no problem but a user mistakenly bought series2c modules. Looking at the advert page it says the s2c has series1 functionality now. I scanned the manual and can’t find anything resembling a simply transparent mode setup.

Can someone point to where the instructions for setting up a series2 like a series 1 are? Or just an example AT string for non-sleeping non-coordinating setup? I have no series2 to play with or I’d just bull my way through.
