Installing CPAD2 modules
After connecting a CPAD2 module to an unused CAN BUS
interface on your Dewetron system, run DEWESoft and go
to the HARDWARE SETTINGS screen, accessed under the
SETTINGS button. Then click on the CAN button.
Select the CAN interface that you connected the CPAD2 mod-
ule to on that screen and set it to work with CPAD2 modules,
as shown in the screen shot here.
If your software does not have this selection on the CAN
screen, please obtain the CPAD2 plugin from Dewetron. This is
a software addon that is free of charge with your CPAD mod-
ules. It was included on a DVD/CD disk when you purchased
your CPAD2 module(s). Or it can be downloaded from our FTP
site.
Additional CPAD2 series modules can be daisy-chained to the
first module. The last CPAD2 module must have the termina-
tor plugged into the last open connector to ensure stable bus
communications.
