So I just tried creating a config with pncconf again. When I don't designate any functions to the pins on the 7i84 linuxcnc will launch but not show the 7i84 in halshow.When i add a function to any 7i84 pin in pncconf linuxcnc won't start and i get this error message:

First config/error, is the 7i84 powered on?
If yes, cable wiring is wrong from 7i97T to 7i85.
-
Second config/error, is Mesa 7i97T powered on?
Is the cable connected to it?
Since network should already be set and working, then probably the wrong card IP address in the ini file.

Yes. the sample hal file uses a 192.168.1.121 IP address:

loadrt hm2_eth board_ip="192.168.1.121" config=" num_encoders=6 num_pwmgens=6 num_stepgens=0 sserial_port_0=00xxxxxx"


The 7I84D is not recognized.

This may be because:

1. The Ethernet cable is not EIA 568B, so the color code is
not correct for the chart in the manual
(check the RJ45 end of the cable)

2. You don't have _both_ VFIELDA and VFIELDB connected to +8 to +24V
on the 7I84

Thanks for your input.
 

Attachment not found


my rj 45 plug looks like this

I have the 7i84 connected to 24V
 

Attachment not found


on the left the calbe marked 55 is 24V an i jumpered it over so both field connectors get 24v
the cable marked 53 is ground. There are no relays or switches between the power supply and 7i84 as per the manual.

I have the 7i97 connected to 5V
 

Attachment not found


The violet cable supplies 5V, the blue one is ground.
The 7i97 seems to work, as I am able to read the handwheel encoders I have connected.

After changing the ip to 10.10.10.10 LCNC starts with Peter's hal file, but the 7i84 still doesn't show up in halshow

Update:

I also have a 7i73 which will later be mounted in the control unit to interface some buttons and encoders, and plugging the cat5 cable from the 7i84 to it and running mesaflash --addr 10.10.10.10 --device=ETHER --sserial
gives this:

which leads me to believe that card is communicating properly

Thanks for your help so far

It looks like the 7I84D has failed somehow.
There is either an issue with the 3.3V supply
or the microcontroller, because neither the
red fault or green activity LED is illuminated.

Is that something I can check/fix myself or should I contact the retailer. The package arrived on friday and I am fairly certain I didn't damage it.

You could check if there is 3.3V power, and if not, maybe trace
backwards (3.3V comes from a switching supply that is supplied
by VFIELDB)

 (Check across the larger electrolytic capacitor
 C30 towards the bottom of the card between TB2 and TB3)

But if its not something obvious, the card should be returned
to the vendor for repair/replacement.

I contacted the vendor and they advised me to order a replacement card and send the defective one back for review. They also informed me that all boards were tested before shipping and most defects are user error. Now, I only connected what is shown in the pictures for a quick test and the card was not working from the start.

Can someone confirm if I made any errors connecting it? (Not to prove anything to the vendor but to save me from scrapping another card)

Looks OK, can you verify that you have +24V
on both VFIELDB pins?
