hi chris

i could not get TXD to flash till i connected the unit to Lady Heather
V5.01.

once the unit was communicating with the LH program (much serial wizardry)
all was well.

Has anyone else received a unit they can't get to work?
I got my unit finally boxed up a few weeks back. The PPS LED flashes and
power LED and RXD LED's light but the TxD doesn't.
I've ordered replacement MAX chips and 74ACT04 chips from Digi-Key but
this didn't solve the problem.
As a next step I've found a Oncore M12 board on eBay coming from China
and this should come in a few weeks.
No serial communications unfortunately.
I've also tried swapping pins 2 and 3 on the DB9 just in case RX and TX
were swapped (although I had originally built the cable as per the
schematic with the kit) but still no luck.
Thanks for any comments.

On this product people are going to want holes drilled and I think a "D"
shape hole for the DB type connector. The holes would allow easy

clamping

but in a two step operation. If I were making these I'd first clamp

the

stock over a pair of 123 blocks, mill the holes, then after I hade a

batch

of these made, hole the holes to hold the part a fixture and then mill

the

edges.

But that said, I could make a pair of these by hand with hack saw, file

and

drill press in about 15 minutes.

I can

then machine around the edges without worrying about clamping. With
pockets though, the torque even when ramping down might break the part
loose.
