I've got a selection of Net3 DMX gateways here - two 4-port, two 2-port and six 1-port.
I've installed v2.0.1 of the gateway configuration editor onto a laptop, set the lappy's IP to 10.101.90.10 with a subnet mask of 255.255.0.0, started GCE, set the address server running, and hooked it up to a PoE switch along with one gateway at a time.
The 4-port and 2-port gateways were no problem - plugged them in, they got a dynamic IP address and GCE announced their presence, and I was able to configure them as I want (which is basically just setting a static IP address).
The 1-port units, though, are a different matter - I can't get GCE to discover them at all. I've seen the note in the Wiki about some units in the past shipping with a 10.4.x.x default IP address so I opened up the subnet mask to 255.0.0.0 in case this was the issue, but it didn't help.
How can I get GCE to see my 1-port DMX gateways?
