Text Capture Buffers
Capture buffers are tools for receiving strings of different formats and from various sources. This process allows building triggers and user reports, in addition to facilitating integration with external devices.
The system has 8 buffers (00-07), each capable of storing up to 150 characters.
Main Applications
| Application | Description |
|---|---|
| Peripheral integration | Data capture from RFID readers, sensors, scales |
| Identification | Storage of customer, cargo or driver codes |
| Custom reports | Inclusion of external data in position messages |
| Automation | Triggers based on captured data |
Available Commands
📦XB Command
Manual loading and query of text buffers. Allows storing up to 150 characters per buffer
→⚙️CXXB Command
Configuration of automatic capture from serial ports with delimiters, timeouts and filters
→Typical Workflow
- 📡 Capture: A peripheral (RFID, scale, reader) sends data to the serial port
- 📦 Buffer: CXXB captures and stores in buffer XB 00-07
- ⚡ Trigger: The corresponding trigger is activated (
XB00+,XB01+, etc.) - 📤 Report: The trigger sends a UC report with the buffer content
- 🖥️ Platform: The server receives and processes the captured data
Capture Triggers
Each buffer generates its own trigger when it receives data:
| Buffer | Trigger | Typical Use |
|---|---|---|
| XB00 | XB00+ | Customer/cargo code |
| XB01 | XB01+ | Route identification |
| XB02 | XB02+ | Driver data |
| XB03-XB07 | XB03+ - XB07+ | Custom uses |
Advanced Configuration
For automatic capture from serial ports, use the CXXB command:
Limitations
XB buffers are volatile - they are lost when the device restarts. For persistent storage, use user variables (UV command).
| Parameter | Limit |
|---|---|
| Number of buffers | 8 (00-07) |
| Maximum length per buffer | 150 characters |
| Persistence | Volatile (lost on restart) |
