CH341A USB Bus Converter Module USB to Serial Module RS232 RS485 RS422 Programmer

Description

Features:
1.Overview:
Full-speed USB device interface, compatible with USB 2.0.
Supports 5V/3.3V voltage supply.

2. Asynchronous serial interface
Emulates a standard serial port for upgrading USB serial peripheral devices or adding additional serial ports via USB.
Hardware full-duplex serial port, built-in method buffer, support communication baud rate 50bps-2Mbps.
Supports 5, 6, 7 or 8 data bits, odd, even, blank, flags and no parity.
Supports serial port transmission enable, serial port ready and other transmission rate control signals and MODEM contact signals.
Supports indirect access to the CH341 external serial EEPROM memory using the standard serial port communication.

3. Printing port
Standard USB printer port, used to upgrade the original parallel printer, compatible with the relevant USB specification.
Compatible with Windows operating system. Even if drivers are not needed on Windows 2000 and XP, the application is fully compatible.
Supports a variety of standard parallel port printers, with optional low speed printing and high speed printing.
Supports the IEEE-1284 specification for two-way communications and supports one-way and two-way transmission of printers.

4. Parallel port
Provide two interface modes: EPPE mode and MEM mode.
The EPP method provides signals such as AS#, DS#, and WR#, similar to EPP V1.7 or EPP V1.9.
The MEM mode provides AO, RD#, WR#, and other signals, similar to the memory read-write mode.

5. Synchronous serial port
With FlexWire technology, a flexible 2-wire to 5-wire synchronous serial interface can be implemented using software.
As a host/master host, it supports 2-wire and 4-wire common synchronous serial interfaces.
The 2-wire interface provides two signal lines, SCL and SDA, supporting four transmission speeds.
