I will try to consolidate these issues under my build log later but a seperate post allows me to appeal to those who know and love ProTune directly.

So for reference I have an EPLC3 SS and ZP5A-INT Zapp BOB and 4 AM882 drives. Following on from my adventures in racking yesterday I'm trying to tune the motors with ProTune and... it really is trying.

I have 'the cable' (DB9 to Rj12), also a USB to RS232 cable with seperate driver (CH41?) and so far 4 different PC's trying to get stable comms to the 882.
I ditched the USB to RS232 lead completely and cut off the DB9 connector from 'the cable' checking in the pinouts from RJ12 connector (using the data sheet from the Leadshine site) so as to re attach it from new, I didnt find any misaligned pins in the DB9. I've used 4 PC's to connect and generally I'm not getting anywhere.

I went to the Leadshine site and downloaded the correct version of the AM882 Protune (according to them) and found it didnt play nice with my legacy XP (up to date as of the April cut-off) and found myself re registering several ocx components at which point I thought, enough, ask for directions!

For what its worth I do get a read from the drives so I know that serial comms are working but every time I try something interesting in ProTune it says in effect comms dropped. I've tried all the dip switches on the 882 to off, and not (although not all on), the 882 is powered up and motor is connected to it, the BOB is not.

I'll send real chocolate Egg to whoever can help me out here. This is driving me nuts. Thanks. Tony.
