Do you have the secondary line voltage plugged into the module?

Subject: [PIC]: Brand new Promate II


Does anyone know any "magic tricks" to get the Promate II to start working
reliably?

I was doing ICSP with the Picstart, which was a little flakey, but then
again, it's not really supported that way..
So, now I have this brand new Promate II, with ISCP module.
My troubles are over, right?

Wrong.

Mostly, it insists that devices are code protected, but sometimes it will
program them.
Then it locks up in "erasing now".

I've loosened/tightened the screws on the module, cleaned both sides of the
zebra strips, and the contacts they hit.

I've double-checked my cable, and called the factory guys and run it past
them.

There's nothing on the target attached to the programming pins, other than
a 100k pullup on /MCLR.

Yes, I am programming with the target's power supply off, and no I'm not
getting VPP or VCC overcurrent LEDs.

I've had probably four succesful program cycles out of 50+ attempts, on
three different target systems (16F627)

As high-dollar programmer experiences go, I'm underwhelmed.

I'm ready to go back to my AVRs, and the 6-wire-off-paralell-port
programmer that's never failed me yet.
