BurookHi Norman... I just remembered i didn't let u know.... everything worked out we made both the wired and the remot control opening work... they loved the item (assuming it will hold its own for the next 10 years or so) -
KiranYes I don’t doubt you. Jutai is one of the most confident companies I came across in China

Indicators and Switches
| Indicator | Status | Meaning |
|---|---|---|
| Power LED (RED) | Illuminates | Power ON |
| CH1 Detecting LED | Continuous | Vehicle detection |
| Slow Blinking | Loop short circuit or insufficient twists | |
| Fast Blinking | Loop open circuit or excessive twists | |
| CH2 Detecting LED | Continuous | Vehicle detection |
| Slow Blinking | Loop short circuit or insufficient twists | |
| Fast Blinking | Loop open circuit or excessive twists |
Sensitivity Selection
Sensitivity and frequency adjustments using 7-way and 10-way dip switch settings:
- Dip switches 6, 7, 8 control CH1 sensitivity (0.8 to 0.015)
- Dip switches 3, 4, 5 control CH2 sensitivity (0.8 to 0.015)
Reset Button Note: The LD-200 must be reset every time a setting change is made to the Dip switches.
Installation Guidelines
- Use ferromagnetic wires for induction coil (up to 500 meters total length)
- Coil cutting size: Rectangle 1.0-2.0m length * 0.8-1.2m width
- Avoid right angles at corners
- Keep product plug and socket in vertical direction during installation
System Integration
JUTAI LD200/202 Double Channels Vehicle Loop Detector Series with direction recognition function for single-channel entry and exit applications.
Compatible Components
- JUTAI One door controller (Model: AC-11)
- JUTAI gate barrier (Model: BR-110)
- JUTAI long-range RFID reader (Model: PUHF-9)
- High-temperature resistance loop coils (Model: JTHT-11)
Operation Process
Entry Process
- Simultaneous Loop Coil Activation: Both loop coils are pressed when car enters
- UHF Reader Activation: LD-200/202 triggers UHF reader at entrance
- Card ID Reading: Reader transmits ID to controller via Wiegand output
- ID Verification and Gate Opening: Controller verifies ID and opens gate barrier
- Vehicle Entry: Barrier arm automatically lowers after vehicle passes
- Safety Assurance: LD-100/102 provides safety and anti-smashing functionality
Exit Process
- UHF Reader Activation: LD-200/202 triggers inside UHF reader
- ID Verification and Gate Opening: Controller verifies ID and opens exit barrier
- Vehicle Exit: Barrier arm lowers automatically after vehicle passes
- Safety Measures: LD-100/102 provides safety during exit process
Direction Recognition
Ensures double channels loop detector does not trigger signal again when car passes another UHF reader, maintaining accurate entry/exit records.
Independent Working Mode
The JUTAI LD-200/202 can function as two independent single-channel loop detectors for standard one-in and one-out parking lots:
- One loop coil triggers reader and reads card
- Other loop coil provides barrier anti-smashing function
- Cost-saving benefit by reducing hardware requirements
