Does anyone have a Cytron Smartdrive Duo 30 and what are the diffrences with a sabertooth in settings?

Folowing the manual and comparing it... I came to these settings... Still have to test it... But maybe someone has some conformation?
# Stop
SendSerial(D0,9600,0)
SendSerial(D0,9600,128)
# Forward
# Motor 1, 63 is full speed forward.
SendSerial(D0,9600,63)
# Motor 2, 191 is full speed forward.
SendSerial(D0,9600,191)
# Differential Turn Right
# Motor 1
SendSerial(D0,9600,63)
# Motor 2
SendSerial(D0,9600,255)
# Differential Turn Left
# Motor 1
SendSerial(D0,9600,127)
# Motor 2
SendSerial(D0,9600,191)
# Reverse
# Motor 1, 127 is full speed reverse.
SendSerial(D0,9600,127)
# Motor 2, 255 full speed reverse.
SendSerial(D0,9600,255)
And what about the Speed Changed setting?
Upgrade to ARC Pro
Synthiam ARC Pro is a cool new tool that will help unleash your creativity with programming robots in just seconds!
If you want speed control, there's two ways to go about it
1) Create a skill control
2) Use a custom movement panel
If you choose #2, there's a $speedleft and $speedright variable which you can use. You'd have to use a little math to determine the speed for each direction.
So i have made a custom movement panel.
Everything works... But it's just one speed...
i managed to found out if i set lower numbers in the script the speed will be lower... But the 2 shuffles for speed won't work.
Would be nice if the sabertooth script was editable or viewable so i can compare
I found Gwen's question... about "ramping" As i understood this was to build up te speed instead of only 1 speed that stops abrubtly (https://synthiam.com/Community/Questions/Movement-Scripting-Help-Please-2983)
I loaded the latest script and changed some perimeters to be compatible with this controller. But it doesn't seem to work for me...
Where the sabertooth increases the speed from a stop. 0-10-9-8-7-6-4-3-2-1-0-1-2-3-4-5-6-7-8-9-10
The Smartdrive Duo increases otherwise 0-1-2-3-4-5-6-7-8-9-10-0-1-2-3-4-5-6-7-8-9-1-0
example smartdrive duo
vs
Sabertooth
I was reallly mindboggling about what to do.
Going to try that and let you know my results. But if i look at the manual that should do the trick
I only need to adjust the speeds and sensitivity, but how that works i allready know
Is driving with the RC option also possible in autonomous mode?
And what is the diffrence exactly between Simplified Serial and RC mode for robotics? I thought i really needed Simplified Serial... (because everyone goes for that with sabertooth in the R2D2 world) I am trying to understand that part
long as it moves with a movement panel, all movements are supported. Read about movement panels here in the manual: https://synthiam.com/Products/Controls/Overview/Movement-Panels-17372
