^The seller told me he didn't know much but that the new firmware gave the unit the ability to "beacon" itself on the network? The current older version its shipping with cant do that, whatever it means. IDK what that means. I got one too and am using it for what sounds like a similar setup. For $30 hard to pass up including relay and all the emitter outlets.......
Then it sounds like the unit has software release prior to 3.0 (see link below), which had the beacon feature and DHCP support. I guess the question is how to get it updated from Global Cache, as I think it may be a challenge to locate it on the network without a beacon feature and no automatic IP address assignment via DHCP. Maybe have to hook up a computer directly to set it up? Which is probably not a big deal.
Edit: Which seller did you purchase from? There are two on there now, and the seller "thetraveler1969" has multiple units.
Edit 2: I called GC support, and it costs $35 to upgrade the GC-100 models, and that includes return shipping. He said they just set up an RMA, and I could (theoretically) have the seller ship it directly to them, which would save me some money. I asked about setting up units prior to firmware 3.0 (no beacon or DHCP support), and he said they have a built-in static IP address and you connect a computer with a crossover cable. For me, I would want to have mine updated to simplify my life during setup. It would still end up being cheaper than an iTach IP2SL, and it would have two serial ports vice the one on the IP2SL. The single concurrent handset connection limitation is not an issue for my setup, as this would only be for the basement theater.
All that sounds right.
If no other probs present themselves ill have no probs just hooking up to the unit with a crossover cable to configure.
Glad to see a couple people picking them up hopefully we can help each other along.
