Problem connecting Ethernet device to mac.

[Zondar]

Hello,

I'm trying to connect an ethernet device to my Mac Studio. It's a GPIB to ethernet bridge, connected over ethernet directly to my mac via a crossover cable. The device should connect automatically via DHCP, whereupon I should be able to open a web page to it. The mac's networking panel says ethernet is not connected, but everything else looks normal.

This all works perfectly fine on my linux machine and also a W10 box, but not my mac. Typing in its http address, which I know, does not work (it just hangs with no response). It's like there's no connection at all. Is there some basic setting that I'm missing, perhaps a security issue or something?

Thank you for any tips you may have!

I think it shouldn't matter, but try with a regular ethernet cable (not crossover).

Thank you for your reply.

A crossover is the correct cable for this, but I tried a normal one too just in case, without success.

It's baffling. As I said, it worked right away with linux and W10, but the "it just works" mac? No.

It's a GPIB to ethernet bridge

Might help if you told us the model? Have you asked on the manufacturer's support forum (if any)?

Is there an active ethernet interface showing in Network settings?

The device should connect automatically via DHCP, whereupon I should be able to open a web page to it.

Wait, does the device expect to see a DHCP server on the other end, or does the device itself offer DHCP to the computer you are connecting?

It's a "Kiss488" (easily searched for). There are down-loadable instructions, but they are only really helpful for windows users. It worked right away without any issues on linux and W10.

I'm not an expert on this topic, but it (typically) expects a DHCP server on the computer to negotiate a connection to it. However, that's not mandatory, since the device tells you via blinking an LED what http address it can be found at (e.g. 169.254.1.80), and then you can just type the address into a browser and it will serve web pages to the computer. Except no connection is actually enabled.

chabig: Ethernet shows up as "not connected" just like in your image.

Thank you for any assistance.
