3 1. Introduction DALI (Digital Addressable Lighting Interface) is the lasted international standard of lighting control interface. DALI to RS485 Converter is designed to transfer control command between RS485 bus and DALI bus. DALI to RS485 Converter has built in DALI Power Supply for DALI Bus. This unique function is suitable for small area DLAI lighting system. 2. Wiring supports both Point to Point and Point to Peer RS485 half duplex network. The wiring method is below.

4 Single DALI Loop HOST PC TCPIP USB RS232 RS485 Converter RS485 RS485 ID=1 DALI Loop #1 Multiple DALI Loops HOST PC TCPIP USB RS232 RS485 Converter RS485 RS485 ID=1 DALI Loop #1 RS485 ID=1 DALI Loop #2 Max 255 RS485 ID=255 DALI Loop #255 Note: The number of is depended on the driving force of RS485 converter. support the maximum number is 3. Quick Set There has a set of communication protocol for to working under Multiple DALI Loops and Remote Control environment. This protocol is showing below: Header Check1 Direction Pay Load #1 Command Pay Load #2 Check sum End 2bytes 2bytes Description: (All data is HEX mode.) Header F1: The fowling data is for DALI control. F2: The fowling data is for setting. Page 3 of 4

5 Check1 Direction Pay Load #1 Command Pay Load #2 Check sum End code Check code #1 = 07h 50: The fowling data is from Host PC to. 54: The fowling data is from to Host PC. Please reference to each command s detail description below. Please reference to each command s detail description below. Please reference to each command s detail description below. Check sum from Header to End code. Low byte only. End code = 55h RS485 ID programming and acknowledge (command code D2 and A1) Notice: Only one is connected to the RS485 network when user is performing RS485 ID Programming. The wiring method of RS485 ID Programming is showing below: HOST PC TCPIP USB RS232 RS485 Converter RS485 RS485 ID=1 The RS485 ID programming command is : F D2 L_ID 00 ADD 55 L_ID: ID for. D2h: Command for Rs485 ID setting. 50h: The fowling data is from Host PC to. F2h: The fowling data is for setting. When the programming procedure is done, the will respond acknowledge as below: Page 4 of 5

6 F L_ID xx A1 xx 00 ADD 55 Reversed, don t care. A1h: Command for responds Rs485 ID setting. L_ID: ID report form. 54h: The fowling data is from to Host PC. F2h: The fowling data is for setting. transfer DALI command from Host PC to DALI network (command code D2) F L_ID DD D2 CC 00 ADD 55 DD=DALI command byte, CC=DALI Data byte D2h: Command code for transfer DALI command to DALI bus. L_ID: ID for. 50h: The fowling data is from Host PC to. F1h: The fowling data is for DALI control. transfer DALI information from DALI network to Host PC. F L_ID DD A2 CC 00 ADD 55 DD=DALI command byte, CC=DALI Data byte A2h: Command code for transfer DALI command to Host PC L_ID: ID form. 50h: The fowling data is from Host PC to. F1h: The fowling data is for DALI control. 1. The third byte of data stream is used to identify the destination of the data. The 50h is from Host PC to and the 54h is from to Host PC. 2. The Host PC is able to recognize any changes on each DALI loop individual light change through the data L_ID DD CC byte on the data stream. Page 5 of 6

7 Query command from Host PC to (command code D3) Host PC is able to query any by using instruction D3h. F L_ID 00 D ADD 55 D3h: Query command for. L_ID: ID for query. 50h: The fowling data is from Host PC to. F2h: The fowling data is for setting. wills response a message as below: F L_ID 00 D ADD 55 D3h: Query command for. L_ID: ID for respond. 54h: The fowling data is from to Host PC. F2h: The fowling data is for setting. Page 6 of 7
