1. Introduction

The DAU01-MOD 2XXX series is a family of network data acquisition and control modules,

providing digital input/output, analog input / output, PWM, counter, relay and other functions. The

modules can be remotely controlled using a set of commands - Modbus RTU or Modbus TCP Protocol.

DAU01-MOD2XXX series provides：

1. 10/100 Mbps Ethernet interfaces supports Modbus/TCP protocol over TCP/IP for data connection.

2. USB 2.0 interfaces supports Modbus RTU protocol for data connection.

3. RS485/RS422 interface supports Modbus RTU protocol for data connection.

4. Modbus gateway function ,when it was set to be the Modbus gateway function then the

Modbus host can communicate through the Ethernet/USB cable via Modbus gateway to control

the other Modbus slave device with RS422/RS485 interface.

The DAU01-MOD2XXX series modules can connect to all communication interfaces simultaneously

but control to access it by one of them in the meantime.

Modbus/TCP and RTU Protocol Supported For Open Connectivity

The DAU01-MOD2XXX series modules support the popular industrial standard, Modbus/TCP and

RTU protocol, to connect with Ethernet Controller or HMI/SCADA software built with Modbus/TCP

or RTU driver and can manipulate it simply and implement your various applications easily. Fig 1.1

is shown a typical MODBUS application.

3. Functional Feature of INIT Mode / Normal Mode

When the module set to INIT mode, then repower the module will restore the default value

of the module. Now Master can use the default setting to communicate with the module

to configure the module.

The MODBUS RTU default setting :

MODBUS ID :01

Baud Rate : 9600 bps

Parity : None

Data length: 8 data bits

Stop bit: 1

The MODBUS TCP default setting :

IP:192.168.1.100

Gateway:192.168.1.1

Subnet Mask:255.255.255.0

Primary DNS:192.168.1.1

Secondary DNS:8.8.8.8

Web port : 80

TCP port : 502

UDP port : 502

MBAP : Enable

DHCP: Disable

After configuring the new IP address/ Baud Rate/ Modbus ID, user should switch to the

Normal Mode. then repower the module or press the reset bottom. Then the module will

work under the new configuration.
