edgerouter configuration for multiple probes on one PC

[danieljdenman]

i've finally gotten around to trying to do this, and i seem to be getting stuck at the end of configuring the edge router. i get through most of your instructions, up to manually defining the IP address and saving that configuration. as expected, i get disconnected from the edge router configuration. but even after changing the Windows network adapter IPv4 address i can't connect to the edge router with any IP (10.2.1.254, 10.2.1.1, 10.2.1.123, 192.168.1.1). perhaps not surprisingly, i also can't get open-ephys [with the edited dll] to recognize that there is a source at 10.2.1.123, it just times out.

since i can't seem to get to the edgerouter configuration, i have to reset the edgerouter to defaults and start all over in order to change anything. i'm going to poke around the internet to see if i can figure out what is happening. did you guys ever have trouble reconnecting to the edge router?

thanks!

Yikes, that is frustrating, sorry. I only did this once (Max configured the other of the two edgerouters that we have) and it just worked that one time. Since I posted those instructions, Max showed me how to save an edgerouter configuration file, so let me try to do that tomorrow and send it to you - this should both make it easier and possibly resolve whatever missed setting there might have been. Other than that, no, I don't think I have any ideas...

Ok, I have uploaded the config file to the multiple-probes page, or find it here. As described on the page, you need to log into the edgerouter, click "system" at the bottom and then "restore config". Let me know how it goes?

[danieljdenman]

it works! at least i can connect to the edgerouter after configuration now. streaming data doesn't work yet, but this seems like openephys debugging. i'll update on that front if we figure it out.

your config file pointed me to two discrepancies, one substantive and one not, with the instructions on this wiki:

1. in the destination NAT rules section, the description of second one [10.2.0.123 --> 10.2.1.123] should be "fpga to computer", not "computer to fpga". this is the not substantive one.
2. in the section manually defining IP addresses, the wiki says:

in eth0 row, click actions->config manually define IP address(es) add both 10.2.X.123/24 and 10.2.X.254/24

but it should say:

in eth0 row, click actions->config manually define IP address(es) add both 10.2.X.1/24 and 10.2.X.254/24

Awesome, thanks, I have fixed both of these things on the page, sorry for those errors... :/

Let me know if it ends up working out. I'm surprised that it working or not would depend on the acquisition software - maybe you can try with spikeglx to see whether it works before assuming it is an openephys problem?

[danieljdenman]

i did get to a solution: not quite sure why yet, but if i connect serially i can get it to work. what this means is:

1. i have both fpgas powered off

2. switch only one on

3. connect whatever acquisition software to it

4. repeat for the second probe.

this seems to be the only way i can get openephys to stream data from both probes. if both are powered on when the first connects, the second one won't find the fpga, whether it's the edgerouter fpga or the directly connected one.

[nsteinme]

Huh. I don't think I had to do that with my setup (I suppose I would have noticed). However, it's definitely the case that windows has various weird things it "remembers" about your ethernet connections, so it might be related to this somehow. Anyway, great that you got it working!

FYI, I used the wiki instructions with a newer EdgeRouter model (ER4 – I couldn't get hold of the Lite). Everything works great with SpikeGLX (haven't tested Open Ephys). I can supply the config file if it's of any use, let me know.

[nsteinme]

Would be great if you don't mind adding it! You could put it in the code repo and add a note about it on the wiki page for that? Great to hear that it worked -
