MODE MANAGEMENT
Within each available Profile, it is possible to select 7 different operating Modes. There are actually 8 Modes, however, Mod e 8
is always reserved for On-Board Programming (OBP). A standard wheelchair is likely to have just 2 operating Modes – Drive
(Mode 1) and Seating Control (Mode 2) – however, it is normal to set all Modes to be available, so that they will automatically
be accessible when an additional Output Module is connected. If they are not programmed to be available, then if an additiona l
Output Module, such as a Bluetooth Mouse Module is connected, the system would have to be programmed to recognize this
new Module.
The parameter that sets whether a Mode is available is Mode Enable. Below is an example of programming to satisfy this
requirement.
However, this programming is not appropriate if it may be required to use just one button or switch to select Profiles and
Modes. For this reason, it is recommended that programming as described in the following section is used.
SELECTING PROFILE AND MODES WITH JUST ONE BUTTON
It may sometimes be required to use just one button or switch to select Profiles and Modes. A typical example would be the us e
of a Buddy Button connected into the External Profile Switch jack socket. The R-net system has been designed to allow this by
applying the following rule.
Each operation of the External Profile Switch will select the next available Profile. Upon reaching the highest available Pro file,
the next operation of the switch will select the next available Mode, regardless of whether the Mode is available in the current
Profile. Curtiss-Wright therefore recommend a programming set-up as below.
In this set-up the External Profile Switch would step through Drive Profiles 1 to 5, then to Mode 2 (Seating Control) and then to
other Modes if appropriate Output Modules are connected.
Note, if the programming set-up in the previous section was used, then the External Profile Switch would step through Drive
Profiles 1 to 5, then it would step through 5 Seating Control Modes, each effectively the same. If more Output Modules were
connected, it would be necessary to step through 5 times for each, before getting back to Drive Profile 1. Likewise, 5 steps
through OBP would be needed to exit that function.
Note, the programming in this section will also work in the correct fashion when separate Profile and Mode buttons are used.
The basic rules are:
The Profile Button will select the next available Profile in the current Mode.
The Mode Button will select the next available Mode in the last Profile in which that Mode was used.
The External Profile Jack will select the same Mode in the next available Profile. When the highest available Profile for the
current Mode is reached, then the next Mode in the next available Profile will be selected.
