To connect the XTRI to the DPU Programmer/Tester, insert the plug from the DPU cable provided with
the Programmer/Tester into the opening on the front of the XTRI shown in Figure 2. The plug has no
polarity and can be inserted into the holes at either direction.
CAUTION: To prevent potential damage to the DPU, DO NOT connect an XTRI to the DPU until all
connectors of the same polarity are removed from the device line of the XTRI.
Follow the instructions in the DPU Manual (P/N 315-033260) to program the XTRI to the desired
address. Record the device address on the address label, which comes with the product, and place it
on the module or on the XTRI front panel. The XTRI can now be installed and wired to the system.
