Version V01.01 (first batch 05-2017)

2.2. Version V01.02 (from 30-08-2017)

This support wheel switches now have two different inhibits:

1. one for releasing the standing position

2. one for the ramp position of the support wheels.

3. Programming the EvO Altus V01.0.1

To prepare the EvO Altus for delivery the next steps have to be executed:

1. Programming the flash of the CSXM

2. Uploading the Default files of R-net EvO Altus

3. Calibrating each actuator

Programming the flash of R-net CJXM

Step 1: open folder

Step 2: Open the program

Step 3: load configuration

Step 4: if successfully loaded, click “Go!”

Step 5: confirm Re-programming

Inspired by life

Step 6: programming in action

Step 7: programming flash finished!!

don’t switch off the chairs whilst programming the flash.

WARNING

Sometimes an error code will appear on the screen. The USB connection did not connect with the dongle,

cannot initialize CAN interface or another error message. Depending on the version of Windows, you

either need to restart the PC or Laptop and try again. Sometime disconnecting the dongle and

reconnecting it to the PC or laptop will also solve the issue. Just repeat the operation until it connects.

NOTE

4. Uploading R-net Default files

Upload the R-net OEM files to the wheelchair using R-net OEM software and dongle.

Therefore we now need to open the CxSM developer software and open and write the R-net file once more.

Now all R-net parameters are programmed.

before you open CxSM developer software, first close the OEM R-net software. The dongle can only

handle one program software at a time.

WARNING

By uploading this file, not all parameters are properly set!

5. Automatically calibration for EvO Altus V01.02

This version has an upgrade where the support wheels have two positions:

1. anti tipper functionality (the wheels are closer to the ground so they work as anti tipper as well)

2. support wheels up for driving up a ramp. (wheels are max. up to make driving on a ramppossible)

5.1

Key to enter automatic calibration mode (ACM)

To enter the automatic calibration mode you need to use the Calibration key tool. This tool is only available from

Karma Directly and is only to be used by trained and authorized persons.

this special key need to connected to the CxSM module, using Inhibit 7 port.

inhibit port 7 to connect Key to.

5.2

Prepare the chair for automatic calibration mode. (ACM)

Before we put the wheelchair in to automatic calibration mode (ACM), the seat needs to be positioned into the right

starting position. To do so, we use the single powered functions of each powered seat actuator.

step 1: negative tilt in flat (horizontal) position

step 2: tilt in flat (horizontal) position

step 3: backrest in vertical position (90°)

step 4: legrest in vertical position (90°)

if the wheels are in “maximum up” position to drive on a ramp, the driving speed will be automatically reduced

by 50%. for normal driving the user is forced to lower the support wheels into “anti tipper“ position. In this

position it is possible to drive at maximum speed.

NOTE

5.3

Enter automatic calibration mode (ACM).

To get into the auto calibration mode, the switch of the key needs to be pushed when switching on the electronics of

the wheelchair. Keep it pushed until you see the normal screen in the joystick module display. Then let go of the key

switch. The wheelchair is now is auto calibration mode.

Make sure you have an elastic rubber band with you. You need this for the automatic calibration of the Wheelchair.

Now push the mode button to go to the seat function mode. If in the seat function mode, select “sit > stand ‘.

Now push the joystick forward and secure it with the rubber band.

The system will now automatically run through a certain sequence,

calibrating each seat actuator at a time.

When the automatic calibration is successfully finished a

long beep tone will sound.

If there is a failure during calibration, two short beeps will sound

make sure you push the switch until the normal driving screen has been shown. letting go too early or holding

too long after the normal screen is shown , will get you out of automatic calibration mode again. This time

windows is there to avoid unintended entering in to the automatic calibration mode.

NOTE

make sure you push the switch until the normal driving screen has been shown. letting go too early or holding

too long after the normal screen is shown , will get you out of automatic calibration mode again. This time

windows is there to avoid unintended entering in to the automatic calibration mode.

6. Error codes for EvO Altus:

The R-net system has been equipped with additional Altus error codes.
