Connection Diagram

RLY-8-PoE-RS485 supports 2 types of control mode Ethernet and RS485 In this section, we will introduce some typical connection:
• Ethernet

NOTE If you directly connect to the computer, you will need to set a static IP. Going by RLY factory settings, you can set your computer IP to 192.168.1.x is 0~254 except 10 , Subnetmask gateway
• RS485 BUS

PC Control of POE Relay Open the Software

Select the network, and then select the network Control button, enter the network control interface

NOTE It may take some time when the RLY-8 has just been powered on, please be patient waiting for the network list

Network Control of POE Relay

NOTE It is recommended to click the "Get Status" button to get the current state when you want to control the relay.

Control the POE relay with RS485 BUS

Reset and Restore Factory Settings

To reset the factory default settings, hold the reset button until the lights begin to flash.
