Introduction

The DL-100TM485S series are the one-channel temperature and humidity data logger module. It contains a single built-in RS-485 communication interface and an LCD indicator to display the module ID, temperature and humidity data, and allows you define the log time interval depending on your application.
The DL-100TM485S series support the Modbus RTU protocol. Refer to Section 2 for more details.
We also provide software Utility that can be used to retrieve log data and display it in a chart on your desktop, and also allow you save the log data into an Excel format file.

Modbus RTU Protocol

The Modbus protocol was originally developed for Modicon controllers by Modicon Inc. Detailed information can be found at http://www.modicon.com/techpubs/toc7.html.

Visit http://www.modbus.org to find more valuable information.
The DL-100TM485S module supports the Modbus RTU protocol. The communication Baud Rate is 9600bps, and the parity, data bits and stop bits are fixed as no parity, 8 data bits and 1 stop bit. The following Modbus functions are supported.

Code	Description	Address
0x01	Read coils status	0xxxx
0x02	Read discrete inputs	1xxxx
0x03	Read multiple registers	4xxxx
0x04	Read multiple input registers	3xxxx
0x05	Write single coils	0xxxx
0x06	Write single register	4xxxx
0x0F	Write multiple coils	0xxxx
0x10	Write multiple register	4xxxx

If the function specified in the message is not supported, then the module responds as follows.

Error Response

00	Address	1 Byte	1 ~ 247
01	Function code	1 Byte	Function code + 0x80
02	Exception code	1 Byte	01

If a CRC mismatch occurs, the module will not respond.
