Have you the details of the lead fitted to the USA machines?
I think we fitted them to all the MicoTurn/MicroMill built. Not just the USA ones.

As far as I can remember, the Micro machines would work externally on a standard pin to pin (or straight) cable - I think this was because the USA could get hold of straight cables more easily. So, the internal cable from the bulkhead to the control was different to the UK machines and had the relevant pins crossed over (ie Transmit Tx -> Receive Rx and Rx -> Tx )
You'll notice from Steve's post that the internal cable pin 2 (9way) is connected to pin 3 (25way) which in effect is a straight connection (ie, Tx to Tx) because 9 way connectors decided to be different to 25 way and swap the functions of pins 2 and 3

Confused ? You will be...

You are correct.

MicroMills and Turns all used different cables the external Being an BI01812N
