Onboard Original Chips
Onboard Original FT232RL And SP485EEN Chips, Providing Better Stability And Compatibility
Galvanic Isolated Design
- Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal
- Onboard unibody digital isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption
Multiple Protection, Safe And Stable
Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightning-proof & ESD protection. Onboard self-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock proof performance.
Transmission Distance Up To 1.2km
The USB Signal Can Be Converted Into A Balanced Differential RS485/422 Signal And The Transmission Rate Is Stable. The Transmission Distance Is About 1.2km For RS485/422, And About 5 Meters For USB.
Multi System Support
Supports Mac, Linux, Android, WinCE, Win11/10/8.1/8/7/XP, Etc.
