Description
Stable data transmission | Multiple device connection | Various system support
- USB expansion to 4-channel TTL (UART) with hardware flow control — independent and simultaneous data exchange for each channel
- Built-in self-recovery fuse and protective diodes ensure stable voltage and current, overload and overvoltage protection, increased immunity to impulse noise
- Built-in voltage level translator with surge and ESD protection — stable and secure data exchange
- 3.3V / 5V TTL level switch for logic level selection
- Anodized aluminum alloy casing, CNC machined, robust and durable construction
- High-quality USB-B connector and IDC connector with reverse connection protection
| Host Port | USB |
|---|---|
| Device Port | UART |
| Baud Rate | 1200bps ~ 460800bps |
| USB Port | Connector: USB-B Protection: self-recovery fuse, ESD protection |
