1. Introduction
The DL-10 is a RS-485 remote temperature and humidity module that gives you real time
temperature and humidity information at the same time. It contains an RS-485 communication
interface and an sensor for measuring temperature and humidity. The DL-10 module supports
Modbus RTU communication protocol for getting measured temperature and humidity values.
DCON Utility Pro provides easy and convenient interfaces for users to configure the module. Based
on an amazing tiny form-factor, the DL-10 achieves the maximum space savings that allows it to be
easily installed anywhere.

How to solve when the DCON Utility cannot find the DL-10
module?
Ensure that the power supply and the RS-485 wiring for the DL-10 are configured correctly, refer to
the Section 3.1 Connecting the Power and the Host PC. If the DCON Utility still cannot find the
DL-10 when normal wiring and power up, please follow the procedure described below:
1. Use the blade of a flat-head screwdriver to set the “Init Switch 1” on the DL-10 to the “ON”
(Init Mode) position, and reboot the DL-10 module.
2. In the Init mode, refer to Steps 2 to 8 in “Section 3.3 Search Module” to execute the search
again.
3. Confirm that the DCON Utility has found the DL-10, use the blade of a flat-head screwdriver to
set the “Init Switch 1” on the DL-10 to the “1” (Run Mode) position, and reboot the DL-10
module.
