I have several Staefa Control System NCRS panels that I want to connect over an ethernet WAN/LAN. The panels can be connected through RS 485 2 wire LAN ports but we don't have any way to wire between our buildings. We do however have ethernet throughout our facilities. Lantronix in California make a device that does that. However, I can't get it to work. The issue appears to be the protocol Staefa uses. Anyone ever try this? Any thoughts as to settings etc?
