Mesa 7i92 Installation, considering old ATX psu for I/O voltage source...

Meanwell supplies will be fine, been using them for years.

I power mine together, actually I think mine are powered directly from the 7i92.

The Mesa I/O are pretty hardy and have no issues using them directly.

No need to worry about card drivers these, pretty much everything is handled via the hostmot2 driver & the hm2_eth driver, which are loaded via hal. Config is done when loading the hostmot2 driver.

Once the hardware side is setup, load the required firmware via mesaflash and then you can almost forget about mesaflash. The rest is getting the ini & hal files done. This is a mix of using the config program of your choice and editing by hand.

 
This video of mine will help.


Its for the 7i76e but its all similar.
 

Still waiting on various parts to arrive in the mail, but I did receive the 5v and 24v Mean Wells today.

I've watched Rod's video a few times and got some good info there, but also ended up looking thru a catalog
full of din rail terminal block parts afterward...


Currently, my work has been on how exactly to configure my 7i92TF/7i85s combination.
It looks like the simplest option might be:


"7i92t_7i85sx2d"


As that should provide the native card functions for a 7i85s, and therefore also have the serial channel for a
7i84d to communicate thru?

Just as a functional check, is that a valid choice for a new 7i92T with the

Trion T20F256 FPGA chip?

Using this configuration, would the encoder pins start from 0 on the P1 header by default, thereby designating
P1 as the connection point for my 7i85s?

If this checks out, I will try to connect the Mesas to my pc today with the network setup for something like a
10.10.10.11 pc address, and then, ping the eeprom 10.10.10.10 address on the 7i92T.

With the new 5v and 24v meanwell psu's wired up and my network settings updated, I pinged the 7i92T:


--- 10.10.10.10 ping statistics ---
48 packets transmitted, 48 received, 0% packet loss, time 48106ms
rtt min/avg/max/mdev = 0.071/0.099/0.158/0.013 ms


The 0.158ms was the first packet, and watching the output, most were very near 0.100ms which verifies
the 0.099ms avg. Does this sound ok for what I have running on this system?

All three cards were connected so that may have had some effect on the numbers...



There was also a solid red LED lit on the 7i84d, but I am guessing that was probably from a watchdog fault, I've
only just connected them so far and haven't done any other configuration yet. Supply voltage was good.

Those ping numbers look OK
(the first is typically longer because it includes an ARP response)

A red LED is expected on the 7I84D since it will have
(as you guessed) at least a watchdog fault when idle

Thanks for the Function check PCW.

Will I need to do anything special code wise during configuration on these, or should it mostly be the normal setup
and then just pin associations / various timing variables?
