4.3 System overview

The DX2-RJM, DX2-RJM-LF and DX2-ACU operate as secondary remotes within a DX/DX2 wheelchair
control system. They connect to a master remote module via the fixed, trailing lead (DXBUS) as shown
in

Figure 3: System diagram

.

Note

:

Not all master remote modules are compatible with the compact remote modules - for more details, see section
4.3.2 Compatible master remote modules.
