Connecting a DPX2 Sensor Package to DX2, DX or DPX3
You can connect one DPX2 sensor package to the "end" of a DX2, DX or DPX3 sensor chain. It is strongly
recommended to use an RJ-12 to RJ-45 adapter for connecting the DPX2 to the final DX2, DX or DPX3 in
the chain.
The maximum number of DX2, DX or DPX3 sensor packages in the chain must be less than 12 when a
DPX2 sensor package is involved.
The following diagrams illustrate DX sensor chain only, but the same principles also apply to DX2 and DPX3
sensor chains if connecting DPX2 to the end of DX2 or DPX3 sensor chains.
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.
DPX Sensor Packages
Most DPX sensor packages come with a factory-installed sensor cable, whose sensor connector is RJ-12.
