Retrofitting a 1986 Maho MH400E

Hello Andy,

Currently, the only differential signal which appears to have been brought out on the cable is Ua1 which you would normally call /A. The other two differential signals Ua0 = /Z and Ua2 = /B should be available on the EXE board at the pin head connector in pins 4 and 1 respectively according to the Heindenhain product info I linked in my last post. If I have noise issues, I'll have to make up a new cble to that green pinhead connector.

For those who speak german, youtuber Talla83 has some really good videos on the MESA cards which I found very helpful...

I have the 5i25, 7i77 and 7i84 all installed and powered, and seem to have the whole complement of pins when I run " show pins".


Just a question about putting the 7i77 in mode 3 to read the jog wheel encoder. Do I need to put the following command into my machine.HAL file, or is this a sticky setting which I only need to send to the 7i77 once, and it remains in that mode despite restarts?
loadrt hm2_pci config="sserial_port_0=300xxx"

[Edit] PNCConf answered my question. It out in set up line in the HAL which includes the config="sserial_port_0=000xxx so I just changes it to 300xxx.

Hi John,

When I load your "gearchange.clp" into classic ladder, I don't see any signal paths. Do you have a tip for me please?

I will post my configuration, with only 5i25-7i77 to test this, if it works in your pc than we will find what is wrong with the other.

It needs to be permanently in the HAL file.

Also bear in mind that the 7i84 has a couple of MPG counters too, when put in the right mode. It is possible that they might be more convenient to wire to (or not)
