Zebra WT6000 USB / Dock Connector Pinout and Charging Behavior
This repository documents the USB, docking, and charging pinout behavior of the Zebra WT6000 wearable computer, based on hands-on reverse engineering and empirical testing.
The primary objective of this work was to:
-
Understand how the WT6000 detects docks and accessories
-
Enable USB data access without the official dock
-
Build a single custom cable that supports both USB data and charging
Zebra’s official documentation is incomplete for this connector, and official accessories are costly. This README aims to provide clear, accurate technical information for repair, development, and reuse. Overview
Key findings:
The WT6000 uses separate pins for USB VBUS and charging power Charging functions in all modes USB data requires dock mode Dock mode is selected by grounding a single pin No resistor is required for USB or dock operation Charger and USB power inputs can be safely bridged
Connector Orientation
Device screen facing upward Pin numbering follows Zebra’s internal numbering scheme The same connector and pinout are used by:
WT6000 device-side port
RS5000 / RS4000 scanner cables
Connectors for this cable can be sourced from ebay, buy using the plug from an RS5000 replacement cable.
Refer to images in this repository for exact pin numbering and orientation. Pinout Summary Pin Function 1 Ground 2 Dock Mode Detect 3 Not connected 4 Not connected 5 USB VBUS (+5 V) 6 USB ID (unused for WT6000 USB) 7 Charger +5 V 8 Charger +5 V 9 Not connected 10 USB D+ 11 USB D− 12 Ground Dock Mode Detection (Pin 2)
Pin 2 determines how the WT6000 interprets the connected accessory. Pin 2 Connection WT6000 Behavior Direct to Ground Dock / USB mode Resistor to GND Scanner accessory identified Floating No accessory Important Notes
-
USB and dock cables use a direct connection to ground
-
No resistor is used or required for USB
-
Resistor coding is used only for scanner accessories (e.g., RS4000, RS5000)
Charging Behavior Charger Pins (Pins 7 and 8)
-
Accept +5 V at all times
-
Function regardless of dock or accessory mode
-
Charging does not depend on USB enumeration
These pins are the most reliable method for powering or charging the WT6000. USB VBUS (Pin 5)
-
Required for USB data enumeration
-
Indicates the presence of a USB host
-
May not reliably charge the device when used alone
USB Data Lines
USB D+ and D− operate as standard USB 2.0 signals
Data becomes active when:
USB VBUS is present, and
The device is in dock mode (Pin 2 grounded)
Combined USB + Charging Cable
A single cable supporting USB data and charging can be constructed as follows:
Bridge the following pins together:
Pin 5 (USB VBUS +5 V)
Pin 7 (Charger +5 V)
Pin 8 (Charger +5 V)
Supply a regulated +5 V source
Connect USB D+ and D− normally
Ground Pin 2 to enable dock mode
Electrical Safety
All +5 V pins are input-only
The WT6000 does not backfeed power
Bridging USB VBUS and charger pins is safe and confirmed by testing
Physical Connector Notes
Zebra’s factory cable uses a heavily overmolded connector filled with adhesive
The overmold can be carefully removed and reused
The original connector shell provides proper retention and strain relief
Rebuilding a custom cable inside the original shell is feasible
Motivation
This documentation exists to support:
Hardware repair
Development access (ADB, recovery)
Custom accessories
Long-term reuse of otherwise locked-down enterprise hardware
It is intended to complement—not replace—official documentation where available. Disclaimer
This information is provided for educational and experimental purposes.
Incorrect wiring can permanently damage the device
Use a current-limited, regulated 5 V power source
Verify pin orientation before applying power
Results are based on tested WT6000 hardware and may not apply universally
