Handheld programming device
The DTT handheld programming device can be connected for programming the R-Net control unit (see Fig. 284).
A handheld programming device enables access to programmable parameters for adjusting the wheelchair settings
to the individual requirements of the patient, and to read error reports and timer information.
Connecting the handheld programming device
1) Switch the wheelchair control unit off.
2) Connect the connection cable for R-Net to the handheld programming device (see Fig. 284/285, item 1).
3) Disconnect the cable between the control panel and controller, and interconnect the handheld programming
device (see Fig. 285, item 2).
INFORMATION: Alternatively the handheld programming device can be connected to an unused bus
slot.
4) Switch on the control unit on the wheelchair and initialise it.
Using the handheld programming device
For further information regarding the installation and application of the handheld programming device, please see
the user manual "DIAGNOSTIC TEST TOOL TECHNICAL MANUAL SK79393" from control unit manufacturer
Curtiss-Wright.

Programming philosophy
Profiles and operating modes
Operation of the R-Net control unit is based on a concept of profiles and operating modes.
A profile is a collection of programmable parameters which influence the operation and performance of the wheelchair.
There are typically 5 profiles, each of which includes different driving characteristics. Profile 1 can be configured for
very low speeds and accelerations, for example, while profiles 2 through 5 contain progressively higher speed and
acceleration values. In this way the user can determine the driving characteristics of the wheelchair by selecting the
appropriate profile on the control panel. While the profiles are primarily used to modify the driving characteristics,
they may also contain other parameters, e.g. for adjustment of the seat.
Typical examples of operating modes are Drive and Seating. The user can select the desired operating mode using
the [Mode] button on the control panel.
Profile management
The R-Net control unit offers up to eight profiles. Five of these are typically used. The Profile Enable parameter
under Profile Management is used to select whether a profile is visible to the user.
The LCD screen on the control panel shows the currently selected profile as a text string with up to 20 characters.
The number of the profile is also shown.
Managing the operating modes
Seven different operating modes can be selected within every available profile. A standard wheelchair normally has
just two operating modes: Drive (mode 1) and Seating (mode 2).
The Mode Enable parameter controls whether or not an operating mode is available.
