RE: TTL converter advice req

["Justin" <justin@xxxxxxx>]

Turns out Maxim is opposite the place where I got my alarm, 5 mins from my
house!
I'll pop round there later, what else shall I try & blag? :-)

Mark,
yep, it's the Powermax. According to wireless-alarms.co.uk it is TTL (look
under pricing for Powermax software).
I don't know the pinouts, but I'm going to try and find out (or guess!)

Ant,
It's a poor man's Comfort ;-)

Thanks,

Justin.

Alternatively, contact Maxim and get two free MAX233 samples. This required
no external components whatsoever.
