I have just completed the installation (addition) of an SV42 to my (already installed) D100-D10A-HS34-D120 system. After firing it up I attempted to configure the DSAB and it found the four original device and not the SV42. After a short delay a nice lady told me I had a "DSAB Error" and all the displays then showed a red bar echoing the error. After hitting finish button on the configuration screen they all seemed to join and be happy, all that is except the SV42. I disconnected the SV42 and got exactly the same results. The DSAB status screen states that all four devices are there and happy. I checked the communications between them ad they all seem to work, twisting the knob on the HS42 sets the baro on both the D100 and D10A. Twisting the heading knob adjusts the heading bug on all three display, so they seem to be talking to each other. What can the error be? I don't recall this happening when I first set up the installation, sans SV42. All the devices have the latest (5.0) firmware.
