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.
