(H485 CH340E)
Features:
Industrial grade usb to rs485 communication module converter TVS
1. Highlights:
• All original chips are used! All use original chips! All use original chips!
• The power supply and signal are fully isolated, with stronger anti-interference ability and safer use!
• ch340e chip, without crystal oscillator, more stable performance!
• Industrial protection: TVS transient suppression protection, electrostatic ESD protection, surge protection, short circuit connection of A and B signal lines and short circuit protection with power supply (short connection without burning)
• Transmission distance up to 1200 meters (tested at 9600bps)
• Support baud rate 256000, higher baud rate for paired mutual transmission
• Multi-system support hot swap, support win98/CE/2000/2003/2008/XP/WIN7/WIN8/WIN10/
VISTA/LINUX/MAC OS X system, USB interface can be hot swapped
• Automatically identify and control the data transmission direction without any handshake signals (such as RTS, DTR, etc.). The mode conversion can be realized without jumper settings, ensuring compliance with existing communication software and interface hardware.
• With power indicator TXD, RXD indicator
2. Product parameters:
1. Power supply: USB 5V
