Features
1. Support USB to RS485/RS232 communication (switched through DIP switch).
2. Using the new CH343G chip, plug and play, compatible with Windows series, MacOS series, Linux and other systems.
3. The on-board TVS (transient voltage suppressor) can effectively suppress surge voltages in the circuit, instantaneous peak voltages, and protect against lightning and static electricity.
4. The on-board self-restoring fuse and protection diode can ensure stable output of current and voltage, prevent overcurrent and overvoltage, and improve impact resistance.
5. There are three LED indicators on the board for easy viewing of the power signal sending and receiving status.
Product parameters:
Product type: Industrial grade USB to RS485/232 converter
Communication rate: 50bps~1000000bps
Host interface: USB
Device interface: RS485/RS232 (switched by DIP switch)
USB interface:
Working level: 5V
Interface form: USB-A type interface
Interface protection: 200MA recovery fuse, ESD static protection
Transmission distance: about 5 meters
RS485/RS232 interface:
Interface form: terminal block
Interface pins: GND, A+ (TXD), B- (RXD)
Direction control: hardware automatically determines and controls the direction of data transmission
Interface protection: Provides 600w lightning protection, surge and 15KV electrostatic protection (onboard 120R balanced resistor)
Transmission distance: RS485 (about 1200 meters), RS232 (about 10 meters) at low speed
Transmission mode: point-to-multiple (up to 32 nodes, it is recommended to add a repeater RS232 for more than 16 nodes (one point-to-point interface can only connect one device, if multiple devices need to be connected, a repeater is required)
Indicator light:
PWR: Power indicator light, when connected to USB, the light will turn on when voltage is detected.
TXD: Transmit indicator light, the light turns on when data is sent from the USB port.
RXD: Receiving indicator, lights up when the USB interface receives data.
USB to RS485/RS232 interface description:
GND: Peripheral connection GND
A+TXD: RS485 connects to A, RS232 connects to RXD
B-RXD: RS485 connects to B, RS232 connects to TXD
