I have a Merlin Gerin Pulsar ESV 8+ UPS, which has a serial DB9
connector on the back.
I think, pin 2 and 3 are for serial communication, but I think the
other pins have Merlin-specific meaning: working on mains, working on
battery, battery quality etc.
The connector is labelled "U-Talk".
Anyone knows how to make the cable, i.e. pin connections ?

thnx
Erik

oops: found the answer already.
It's a straight-through DB9-male to DB9-female cable, pin 4
unconnected.
Appeared, I bought the cable with the UPS (second hand, US$35 !)
