Mirac Dripfeed and/or serial program transfer. Help!

Post by Enline » Wed 03 Jun , 2020 17:41 pm

Hi,
I have an old Denford Mirac CNC Lathe in good condition. (Not Mirac PC)
But I can not transfer programs to the machine via RS232.

I have the cable 9 to 25 pin from PC to machine.
I checked the settings in the machine software.

Tried to send something to PC Terminal program but nothing shows up.
The machine tells me that it has sent a number of lines and letters but nothing comes up on the pc terminal program

I also tried to send a short program to the machine but nothing happens. It just wait...

The 25pin on cabinet wall are internally connected to the machine pc 9pin serial port com 1.

What PC software can I use to transfer programs?
Should it work with TeraTerm or Hyperterminal?

Earlier I reinstalled the software when I changed to a flashdisk.
Is it possible that I missed to install some software/drivers for the serial interface?

In the Denford folder i can se dripfeed.go and .exe. How can I use this program?
I also found a RS232.DRI containing som cryptic letters but also some plain text.
Right now when I'm writing this I saw a line of text in this file saying:
DENFORDLINK$Software must be run with GO program$ñRunning with old GO programU‰åì...

Does it mean that I shall start the application with MIRAC.GO instead of MIRAX.EXE ?
In Autoexec.bat the first an only line is mirac.
So I guess the mirax.exe is called. Right?
I will try to type mirac.go in autoexec.bat to see what happens.

I dont remember that I ran an install after replacing the hdd to flash.
Maybe I just put the complete folder into a denford folder..
Can that be the problem?
The machine works, it's just the serial transfer that is dead.

Is it possible to upgrade the software?
What software is compatible wich this machine?
The controller board is a LCB3.
Where can I find a complete set of installation files?
I checked the download page but I dont understand wich one that is correct for a Mirac from 1993.

The software version is Denford Mirac v2.16
Serial EO 4368
Serial of electronics 67381
DEC 1993

I really hope and look foward to get some usefull info from someone here at the forum.
