Chapter 4: Connecting External Equipment (Optional)53Repeat the same steps to cascade more DPX3 sensor packages.3. Connect the first DPX3 sensor package to the PX3TS by plugging itscable's connector into the RJ-45 SENSOR port of the PX3TS.Connecting a DPX2 Sensor Package to DPX3You can connect only one DPX2 sensor package to the "end" of a DPX3sensor chain. It is strongly recommended to use an RJ-12 to RJ-45adapter for connecting the DPX2 to the final DPX3 in the chain.The maximum number of DPX3 sensor packages in the chain must beless than 12 when a DPX2 sensor package is involved.When connecting a DPX2 sensor package containing three DPX2sensors:A maximum of nine DPX3 sensor packages can be cascaded because12-3=9.When connecting a DPX2 sensor package containing two DPX2sensors:A maximum of ten DPX3 sensor packages can be cascaded because12-2=10.
