Getting Started
This article guides readers through the process of installing USB to TTL drivers for a multiplexer board, including hardware preparation, driver installation, and troubleshooting tips for ensuring successful signal conversion.
Driver Installation
Hardware Preparation
Operation Steps
- Plugin Micro USB cable to multiplexer board. The "POWER" LED turns on at the same time.
- Driver Installation:
- V1.0 uses FT232R USB to TTL chip, please click here to download Driver.
- V2.0 uses CH340 USB to TTL chip, please click here to download Driver
CH340 driver is free to install for most of Windows OS, if you find there is no COM Port in Device Manager, please download the driver and install it.
After the driver installed completed, please open Control Panel -- Device Manager in your PC. You will see a new port.
- please do not plug two or more 5V to aviod to burn the chip. And, do not connect 5V if already connected from Micro USB.
- Multiplexer board is divided into Area A and Area B. Area A includes Micro USB、ATTL and A232 interfaces. Area B includes BTTL、B232、B485 interfaces. The signal can be convertered between A and B.
- The signal in the same area can't be convertered. For example, ATTL can't be converted to A232, but it can be convertered to B232.
- Only one input in the same area, but it allows to have multiple outputs.For example，if micro USB interface in A is input，multiplexer can be allowed to have 232、485 and TTL as outputs.
