Connecting a DPX2 Sensor Package to DX
You can connect only one DPX2 sensor package to the "end" of a DX
sensor chain. It is strongly recommended to use an RJ-12 to RJ-45
adapter for connecting the DPX2 to the final DX in the chain.
The maximum number of DX sensor packages in the chain must be less
than 12 when a DPX2 sensor package is involved.
When connecting a DPX2 sensor package containing three DPX2
sensors:
A maximum of nine DX sensor packages can be cascaded because
12-3=9.
When connecting a DPX2 sensor package containing two DPX2
sensors:
A maximum of ten DX sensor packages can be cascaded because
12-2=10.
When connecting a DPX2 sensor package containing one DPX2
sensor:
A maximum of eleven DX sensor packages can be cascaded because
12-1=11.
