For each I/O module, one Terminal Base is required - TB-1
Figure 35 "National Instruments rail connected to DECT Messenger"
(page 122) shows how one rail with National Instruments I/O modules is
connected to DECT Messenger. On this rail there can be various types of
I/O Modules. The maximum number of modules for each rail is eight. The
modules shown in Figure 35 "National Instruments rail connected to DECT
Messenger" (page 122) are examples only.
