1. Introduction

The DGW-521 is a communication gateway between the
Modbus RTU/DCON and the DALI (Digital Addressable
Lighting Interface) protocols, and allows a host PC, PAC, or
TouchPAD to access DALI devices by providing three
interfaces that enable conversion from RS-232/RS-485/USB to
DALI. The module provides a built-in DALI power supply that
can be enabled or disabled via a switch. DALI is an
international standard for lighting control interfaces, and is
suitable for DALI lighting systems covering small areas. The
maximum length of the DALI signal cables cannot exceed 300
m.
The features of the DGW-521 are as follows:
1. Conversion between RS-485/RS-232/USB and DALI
Interfaces
2. Easy Deployment: The ID Code can be written by the RS-
485 Interface
3. Simplified Wiring Process
4. Built-in DALI Power can be enabled or disabled using a
Switch
5. 1500 VDC Isolation
6. ±4 ESD Protection for the RS-232/485/USB Data Line
7. ±4 kV EFT Protection and ±2 kV Surge Protection for
Power Line
8. DIN-Rail Mounting
9. Wide Operating Temperature Range: -25 °C ~ +75 °C
