For each I/O module, one Terminal Base is required - TB-1

Figure 35 "National Instruments rail connected to DECT Messenger"

(page 118) 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 118) are examples only.
