Introduction
Multiplexer is a multi protocol converter which is composed by multiple interfaces for using controller
communication. Multiplexer supports conversion interfaces among USB, TTL, RS232, RS485, and
allows to have one input and multiple outputs. It's more convenient for many kinds of controllers to
communication.
Power Supply
Supply Voltage is 5V ，and is divided into two way.
1. via Micro USB data wire.
2. Any pin 5V .
Note：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.

- Page 2 PIN Function Description Points to note: 1. 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. 2. 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.
