DL-100TM485
Introduction
The DL-100TM485 is a 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-100TM485 supports 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.

2 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-100TM485 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
0x01 Read coils status
Address
0xxxx
0x02 Read discrete inputs
0x03 Read multiple registers
1xxxx
4xxxx
0x04 Read multiple input registers 3xxxx
0x05 Write single coils 0xxxx
0x06 Write single register
0x0F Write multiple coils
4xxxx
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.
