Base 8 vs. Base 16 Port Number Systems

With the advent of the TBX-Tribus card and the ever evolving technology to a 16-channel port system, Base 8 and Base 16 port number systems were created.

Base 8 Port Number System

The Base 8 Port Number System splits 16 ports between a top and bottom group. The bottom group starts with 1 through 136; the top group consists of ports 137 through 272 (see Figure 37).

EXAMPLE: This means that if you have an AIO-16 in slot 1, ports 1–8 and 137–144 will be used by the AIO-16 card. Alternatively, if you have AIO-16’s in slots 1 and 3 and an AIO-8 in slot 2, the following port mapping applies:

Ports 145-161 are not used when an AIO-8 card is in the slot AIO–8 Ports 9–16

AIO-6 Ports 17–33 and 162–178
