Problem (Issue) Statement:	How to connect multiple XP-M2000i/XP-M2300i controllers to Server PC via RS485 network?
Description:	A guide to connect multiple XP-M2000i/XP-M2300i controllers to Server PC via RS485 network.
Related Software:	NA
Related Hardware:	XP-M2000i XP-M2300i
System Application:	Door Access System Car Park Access System
Symptom and Finding:	NA
Cause:	For first time connection on multiple XP-M2000i/XP-M2300i controllers to Server PC via RS485 network.
Solution:	Note For RS485 wiring connections between the controllers and the Server PC, the Daisy Chain* connection topology is the recommended wiring connection.* The address of the controller must be unique (ranging from '00' to '15'), I.e. no two controllers in the same RS485 connection network can have the same address. Each RS485 network bus can support up to a maximum of 16 controllers. Knowledge Base Link Users can refer to ID-000037 How to Configure RS485 Address for XP-M2000i_XP-M2300i controller? for instructions to configure the RS485 address for XP-M2000i/XP-M2300i controller. Warning! RS485 wiring connection using the Star* topology may result in controller communication issues!* Summary Please follow wiring diagram as below: Step 1: Wiring diagram for multiple XP-M2000i/XP-M2300i controllers to the Server PC via RS485 network:
