R-Net Programming Assistant

A digital cheat sheet for therapists and technicians. Optimize Alltrack performance, configure drive profiles, and troubleshoot issues safely and effectively.

! Protocol: The Safety Net

Before making any software adjustments, you must execute these three mandatory steps. Neglecting them risks losing the factory baseline or masking mechanical failures.

Step 1: Operation Fishing Rod

Connect your Wi-Fi/USB dongle and immediately perform a "Read from Controller". Never write before reading.

Step 2: Baseline Backup

Save the original file as Client_Original_Baseline. This is your only way back if new settings fail.

Step 3: Mechanical Verification

Check tire pressure and Center of Gravity (CG). Never use software to fix mechanical imbalance.

Voltage Warning: Monitor battery voltage under load. A drop > 2.5V indicates hardware issues (batteries/cabling) that programming cannot fix.

Quality Control & Verification

Digital checklist for final verification before user handover.

Baseline Backup: Original factory settings saved ("DO NOT TOUCH" file). Mechanical Check: Tire pressure and CG balance verified. Incremental Changes: Acceleration adjusted in steps of max 5%. Boost Function: Torque set to 90%+ for high-speed (8.5 mph) or rugged use. Reverse Limits: Reverse speeds max 25-30%. Stability: Turning speeds reduced (7-9%) for high-speed motors.

R-Net Programming Guide

A "cheat sheet" for clinicians and technicians to optimize wheelchair performance across various environments.

I. The "Safety Protocol"

Always follow these three steps before making software adjustments:

1. Read from Controller: Connect Wi-Fi dongle and immediately "Read" current settings.
2. Save "Untouchable" Baseline: Save original file (e.g., "ClientName_Original_DO_NOT_TOUCH").
3. Mechanical Verification: Verify tire pressure and seat balance (CG). Do not use software to mask mechanical issues.

II. Parameter Definitions

Speed (Voltage): Sets the maximum velocity the chair can reach.
Acceleration (Rate): How quickly the chair builds speed. High = jerky; Low = smooth but potentially sluggish on carpet.
Power (The "Linebacker"): Defines overall current limit and strength for hills or resistance.
Torque (Low-Speed Boost): Extra surge at low speeds to "pop" over thresholds without stalling.

III. Factory Pre-Sets

Power: Usually 100% for maximum capability.
Torque: Usually 100% (or 80% baseline).
Profiles: Profile 1 (Slow Indoor) → Profile 5 (Max Speed).
Joystick Deadband: Standard is 10%.

IV. Environment-Specific "Starting Points"

1. Indoor Precision

Speed: 30% to 40% of max.
Acceleration: Set to 1 or 2 (Prevents jerking).
Power: Can reduce below 100% to protect furniture.
Torque: Maintain at 80%.

2. Standard Outdoor

Speed: 60% to 80% (User preference).
Acceleration: Increase in steps of 5 for ramps.
Power/Torque: Keep at 90% to 100%.

3. Rugged Outdoor

Speed: 100%.
Acceleration: Higher to "attack" obstacles.
Power: Must be 100%.
Torque: Min 90% (Triggers Boost Current).

10 Essential Factors for Success

Baseline Backup: Operation Fishing Rod.
Mechanical First: Tires and CG.
Speed vs Accel: Max Velocity vs Build-up.
Power vs Torque: Overall strength vs Low-speed boost.
Env-Specific Profiles: Separate indoor/outdoor.

Surface Resistance: Shag carpet needs higher torque.
Incremental Adjust: Steps of 5% only.
High-Speed (8.5mph): Min 90% Torque required.
Tremor Dampening: Increases stopping distance.
Load Diagnostics: Drop >2.5V = Hardware issue.
