Emplode Connectivity

Emplode Connectivity - 13/09/2000 06:24

I have had my Empeg for a few days now and I have noticed a few "Connectivity" bugs/quirks.

When I start emplode it never finds my Empeg, I have to click options then click ok for it to find my Empeg on USB. I turned off the ethernet as it seemed to take longer with it on.

Also I cant seem to get Emplode to sync via ethernet.

I'm on a switched network so that may be causing my problems.
The Empeg is getting an IP address as I can ping it once it is up.

How does Emplode communicate with the empeg?

thanks

When emplode is loaded, it tries to find the empeg-car in the locations that you've checked in the Options dialog.

This is done in the foreground, and it's given about 5 seconds to each discovery method (serial, USB, ethernet) to find empegs. This is why turning off the ethernet seems to make it faster -- it does make it faster.

However, sometimes the USB discovery doesn't work first time, so you occasionally have to hit the Refresh button (or take a round-trip through the options dialog). This usually fixes it.

As for the ethernet problems, is it finding the unit in the discovery dialog? If it is, then it's something else, and we'll need to look deeper.

It is not finding the unit in discovery.

I am running Win2K SP1

The empeg is in a different subnet. Which is I'm sure the problem....

That is the problem. The discovery is done with via broadcast packets. This discovery will make it through the switch but will be dropped by the router.

This is correct.

They're also subnet-directed broadcast packets (i.e. they're addressed to x.y.z.255, rather than 255.255.255.255). It's not just a case of your router dropping broadcast packets indiscriminately. The subnet-directed packets aren't going to make any sense on the other subnet anyway.

There's a fix in v1.01 that allows you to specify a unicast address for your empeg. This will be routed correctly.

I'm not sure about the ETA for v1.01, but we're hoping to get it out soon.

I just recently got around to buying a network hub to do away with some of the thin coax lying around the place (and more importantly to let me use the ethernet connection on the Mk2!)

I am having some trouble getting Emplode to talk to the empeg over ethernet. Emplode detects the ethernet connection in the discovery phase, but if I select that as the connection, the progress bar appears to indicate downloading from the empeg, but it freezes about 10% of the way across and Emplode hangs.

All the machines in the network are on the same subnet, and I can ping the empeg successfully.

Is there something I am missing?
