The latest version of the GRouter4 firmware, version 4.14.011, is now released. Download the Ethernet router firmware or the Wifi router firmware.

Summary

  • Added reset to defaults for web user, password, and port with the “Service App” button on bootup.
  • Changed the reset IP address/port to defaults to be only the “Service Router” button on bootup.
  • Holding both “Service Router” and “Service App” buttons on bootup resets both the IP address/port and the web user/password/port.

Adept Systems Website Makeover

March 18, 2011

You may have noticed that our website is sporting a new look this week!

The alternative logo now takes center stage on the site for a cleaner look. The colors have been updated for a fresh feeling. And the navigation has changed a bit. Our product section no longer goes directly to the online ordering catalog. Instead, we are adding more detailed product information to make the selection process simple.

If you have any questions or suggestions about the site, feel free to shoot us an email!

3. Conclusion

March 11, 2011
This entry is part 11 of 11 in the series Lon over IP (709.1/852)

As this article has outlined, the open 852 standard protocol provides many beneficial features for tunneling CN protocols over IP. Because tunneling 709.1 over IP-852 is supported by multiple choices for commercially available routers, the LON systems integrator has the capability to leverage building IT infrastructure much more conveniently and potentially more cost effectively than [...]

2.4 CN over IP Bridging

March 11, 2011
This entry is part 10 of 11 in the series Lon over IP (709.1/852)

Another difficult integration problem is for legacy LON network management devices that do not support LON routers. This prevents connecting remote LON channels using CN/IP routers since there is no way to configure the router. Another application is where the remote CN channels want to share the same subnet, have low traffic and it is [...]

2.3 852 to 852 Bridging Router

March 11, 2011
This entry is part 9 of 11 in the series Lon over IP (709.1/852)

Because 852 is a full featured tunneling protocol, it can be repurposed to solve some uncommonly difficult integration problems. The 852 protocol is not limited merely for routing from a CN channel over IP to another CN channel. But can be used to build multi-tier backbones on IP with routers that route from one IP-852 [...]

2.2 IP LAN for high speed CN backbones

March 11, 2011
This entry is part 8 of 11 in the series Lon over IP (709.1/852)

Since the IP Ethernet LAN channels such 100/1000 Base-T, can support much higher traffic speeds than CN channels, there are well suited as a backbone for large CN installations. This also makes it easy to attach monitoring and management tools. They just need an 852 interface.A n example is show in the figure below.

2.1 Multi-site building automation networks over an IP WAN

March 11, 2011
This entry is part 7 of 11 in the series Lon over IP (709.1/852)

Once of the complications when tunneling CN protocols over an IP WAN is that there is no guarantee that packets won’t take more than one router through multiple IP switches and routers endemic to IP WANS. When this happens packets can get out of order. This can be problematic for an automation network depending on [...]

2. Applications of the CN/IP Routers

March 11, 2011
This entry is part 6 of 11 in the series Lon over IP (709.1/852)

There are two primary applications enabled by 852 CN/IP routers. These are remote connection s of multi-site or multi-building CN networks over a WAN and using an IP network LAN as a high speed backbone for a CN network.

1.5 Configuration

March 11, 2011
This entry is part 5 of 11 in the series Lon over IP (709.1/852)

852 management packets provide both device parameters and channel parameters. Device parameters include information such as: IP address, IP port, Name, and Address of configuration server. A channel is a logical grouping of 852 devices that all can send information to each other. The lines of communication are open in both directions and to all [...]

1.4 852 Protocol Packets

March 11, 2011
This entry is part 4 of 11 in the series Lon over IP (709.1/852)

Two types of packets are used by the 852 protocol. These are CN Data packets and 852 Channel Management packets. Both packets use a common packet header. The payload of a CN Data packet is the 709.1 LPDU (Link Layer Protocol Data Unit) (See diagram below). The payload of a Channel Management packet is configuration [...]
