Friend has a Koike D11

Something like this to start and then try Xon/Xoff flow control if that does not work

Try something like "\x02 GOOX0 \x03" and see if you get movement and an ACK

To clarify the sequence is normally something like

DNC                 -  ENQ

CONTROLLER - ACK

DNC                  - "\x02 GOOX0 \x03"

CONTROLLER - ACK  (or NAK if not possible)

DNC                  - EOT

CONTRLLER    - ACK

Trouble is that the programmer can have it work any way they want, so there will be a lot of trial and error unless you have
a specific programming manual for it

Thank you! I received an incomplete bits of information. I received !R and I'm quite not sure why? Any clue? Possible the cable is bad?

Sorry missed this one, didn't get an email for some reason.

The ASCII charactors are outside the range normally used for control chars

! is 0x21, but R is 0x52 and definately would not be used for communicating as it means radius in every flavour of G Code I have ever seen.

The trouble with serial comms is that when buffers are displayed they will contain all sorts of numbers which correspond to ASCII charactors.
Most of it is just random rubbish.
You have to know what is significant (ie what is expected)

It is often easier to display the recieved data as hexidecimal and then the control charactors show up, a lot just get displayed as a blank space otherwise.

The first step is usually to send various enquiries and look for an ACK or NAK back (0x06 or 0x15) but without a programming guide and the machine to play with I am just guessing

PS

Have you seen this?

Looks as though another user got it working with a DNC link program, hopefully he will respond if you contact
