how to setup mesa 7i83

Hi,

I have a mesa 7i83 but i dont know how to make it working.

I tried connect the 7i83 to pc by ethernet cable, powered the 7i83 by 24VDC but didnt see anything happen and cant also ping to the 7i83.

Can anyone guide me how to set up it?

The 7I83 is not an Ethernet device, its is a Sserial device so will connect to most of Mesa's motion cards

so what Mesa's motion cards i should get? i 'm having mesa 5i25 too

You could use a 7i74, 7i85, or any other db-25 daughter card with a smart serial port (that is most of them) between your 5i25 and 7i83,
Which one will be the best choice will depend on what you might need it to do.

i got 7i74, after connecting 5i25 --> 7i74 ( powered 5V via TB1 not cable) --> 7i83 ( with 24V supply), i installed firmware 5i25_7i74x2, now what i need to do next? i just want to send a simple analog signal to 7i83 output.

I dont need to install firmware for 7i83, right?

I want to use Port 3 of 5i25 channel 3 of 7i74 so what config string should i use? Does it like:
loadrt hostmot2
loadrt pci_hm2 config = "sserial_port_2=000xxx"

No, you don't need to install firmware for the 7i83. but you do need to install firmware on the 5i25 for the 7i74.

I'm not sure what your config line would need to be. Maybe PCW will chime in.

"sserial_port_0=00000000"
would make sense for a 7I74X2 config with only the first port (on P3) used
(and all 8 channels of port 0 set to mode 0)

If you use all 16 channels (a 7I74 on P3 and P2) you could use
"sserial_port_0=00000000 sserial_port_1=00000000"

Thank you very much for help,

so in "sserial_port_0 = 00000000" the serial_port_0 is controlled by P3, 8 number zeros are 8 channels, but:

What do you mean about "mode 0", are there some other modes or it just means enable and disable? Where can i find these config strings ? I read document of 7i74 but didnt find it out

I also wanna know what are hal_pins name to control, is that like " hm2_5i25.0.7i74.0.1.analogout1" i found this type name from gnipsel.com/linuxcnc/configs/7i77.html . But i dont understand what do numbers mean?

I think a simple way to send an analog signal to 7i83 is:
Use M66-67 command, connect pin "motion.analog-out-NN" to "7i74 hal pin"

The analog out names should be like:
hm2_5i25.0.7i83.0.1.analogout0

i'm using 7i74x2 firmware.
the "sserial_port_0=00000000" will set P2 to mode 0

the "sserial_port_0=00000000 sserial_port_1=00000000" wont set P2 and P3 to mode 0

the "sserial_port_0=xxxxxxxx" will set P2 and P3 to mode 0



below is my config file:
it shows bug :
./5i25.hal:61: Pin 'hm2_5i25.0.7i83.0.1.analogout0' does not exist
