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 is divided into two way. via Micro USB data wire. Any pin 5V
do not plug two or more 5V to aviod to burn the chip. And, do not connect 5V if already connected from Micro USB.

PIN Function Description

Points to note Multiplexer board is divided into Area A and Area B. Area A includes Micro and A232
interfaces. Area B includes 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 micro USB interface in A is can be allowed to have and TTL as outputs. POWER:power indicator AR->BT The interface in A as interface in B as output BR->AT The interface in B as input, the interface in A as output

Usage Direction

Multiplexer need to install driver before you use. Driver installed completed, please open Control Panel -- Device Manager in your PC. You will see a new port. driver download According to the following connection it. 4.Plugin the A to B USB to UNO

STEP 3 Program a sample code for your Arduino UNO Library installation void setup

Serial.begin 115200 void loop

Serial.write Serial.read ;

STEP Send and Receive data We need a serial monitor for monitoring data. There're lots of good tools like putty,CoolTerm and so on.In this case, we choose CoolTerm to do this.

Please set the baud rate to 115200 bps and com port.Back to the main interface, click Connection-Send String, the following dialog will open.

You can send the string in this dialog. The string received can be showed in the other port UNO port .
void setup

Serial.begin 115200 void loop

Serial.println delay 500 ;

Other Reference Connection
1.TTL to 232 converter
2.USB to 485 converter

PINRS-232 1 DCD 2 RXD 3 TXD 4 DTR 5 GND 6 DSR 7 RTS 8 CTS 9 RI
