SPE Port Connection/Wiring
Use an RJ-11 cable (6" max. length) to connect the NXC-MPE to an AXB-SPE Slave Port
Expander.
The SPE OUT port on the rear panel of the NXC-MPE connects to the EXPANSION IN port on the
rear panel of the AXB-SPE (FIG. 10).
You can daisy chain multiple AXB-SPE's by connecting the EXPANSION OUT on the primary
AXB-SPE to the EXPANSION IN port on the secondary, as shown in FIG. 11. The connecting RJ-
11 cable should not exceed 6 inches in length. Repeat this process to connect up to nine AXB-
SPE's.
