Dtech Usb To Rs232 Ten-light Serial Cable
This product is a high-performance USB to RS232 ten-light serial port conversion cable, designed to meet the communication needs between modern computers and traditional RS232 devices. It uses a high-performance conversion chip that can stably and efficiently convert the USB interface signal into RS232 signal to achieve seamless data transmission. The product has ten signal indicator lights that can intuitively display the power status, data reception and transmission direction, and the working status of each signal line, making it convenient for users to monitor the operation of the equipment in real time and discover and solve problems in a timely manner.
Function Parameters
1. USB2.0 standard, supports hot plugging, plug and play; compatible with EIA/TIA RS232 standard.
2. Support baud rate: 300bps-460800bps.
3. The product has ten signal status indicators to display the power status, data transmission and reception, transmission direction and the working status of each signal line, which is very convenient for engineers to check the communication status of each signal during debugging.
4. Support MODEM contact signal, DCD, RXD, TXD, DTR, GND, DSR, RTS, CTS, RI.
5. Electrostatic ESD protection: ±15KV IEC1000-4-2 air gap discharge. #10KV IEC1000-4-2 contact discharge.
6. Support WinXP, Win7, Win10, Win11, Linux, Mac and other systems.
7. Adaptable temperature: -20°C~70°C. humidity: 5%~95%
8. Wire material: braided mesh aluminum foil. Double-layer shielding has strong anti-interference ability, and the twisted pair USB data cable has more stable signal transmission
