serial cable for Merlin Gerin Pulsar ESV 8+ UPS
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

Appeared, I bought the cable with the UPS (second hand, US$35 !) .... :-) Erik
