Ultimate Guide to Castel Protocol GPS Tracking Devices
The **Castel Protocol**, commonly assigned to **Port 5086**, is a high-performance communication standard for vehicle telematics. It is widely used in OBDII plug-and-play devices (IDD series) and industrial hardwired trackers (HT/MPIP series).
1. Device Model Comparison
| Series | Models | Type | Best Use Case |
|---|---|---|---|
| IDD Series | IDD-213G, 212GL, 213T, 213L | OBDII Plug-in | Light vehicles, Car leasing, Insurance |
| HT Series | HT-196R, HT-192 | Hardwired | Hidden installation, Anti-theft |
| MPIP Series | MPIP-618, 619, 620 | Industrial | Heavy machinery, Construction assets |
| PT/SAT | PT-718, SAT-802 | Portable | Personal tracking, Asset recovery |
2. Technical Wiring Diagram (HT & MPIP Series)
Standard 4-Wire Configuration
- Red Wire (Power): Connect to Constant +12V or +24V Vehicle Battery.
- Black Wire (Ground): Connect to Vehicle Chassis (Negative).
- Orange/White Wire (ACC): Connect to Ignition Switch (Detects Engine On/Off).
- Yellow Wire (Relay): Connect to fuel/power cut-off relay (86 terminal).
Warning: Ensure a fuse (3A-5A) is installed on the Red wire to prevent device damage from power surges.
3. SMS Configuration Commands
To initialize a Castel device, send these SMS commands to the SIM number inside the tracker. Replace 123456 with your device password (default is usually 123456 or 000000).
A. Set Server IP and Port
Format: adminip123456 [IP_ADDRESS] [PORT]
Example: adminip123456 103.30.6.40 5086
Example: adminip123456 103.30.6.40 5086
B. Set APN (Network Access Point)
Format: apn123456 [APN_NAME]
Example: apn123456 ://operator.com
Example: apn123456 ://operator.com
C. Set Upload Interval (Moving)
Format: run,123456,10 (Uploads every 10 seconds while moving)
Example: run,123456,30
Example: run,123456,30
D. Remote Fuel Cut-off
Format: 555 (Enable Cut-off)
Format: 666 (Resume Fuel)
Format: 666 (Resume Fuel)
4. Troubleshooting Common Issues
- Offline Status: Check if GPRS is enabled on the SIM card and verify the APN settings.
- No GPS Fix: Ensure the device label “Side Towards Sky” is facing up and not blocked by metal.
- Protocol Errors: Confirm your tracking platform supports the Castel OBDII Protocol on the specific port 5086.
