Outstanding Issues

  1. i.Lon Config Server (ILCS) bug. When using the ILCS where both GRouter4’s and i.LON 600’s are on the same channel, and there are more than two or three GR4 devices before the i.LON 600’s in the channel list, the ILCS will time out waiting for the i.LON 600 channel routing packets before completing channel configuration and restart the channel configuration. This never allows the channel to complete configuration. This is a bug in transaction handing of the ILCS as an 852 compliant configuration server should never time out of a transaction. When the GRouter4’s occur before the i.LON 600 in the channel list the i.LON 600 has to process the channel routing requests from the GRouter4’s first which delays its response to the ILCS. The workaround is add the i.LON 600’s to the channel before the GRouter4’s. A compatibility mode will be added to a later version of the GR4 firmware.

The GR4 is the price/performance leader of LonTalk routers.
