Interfaces & Indicators

With Multiple LED Indicators, Easy To Monitor The Operating Status

RUN	Ethernet port indicator, blinking when Ethernet port normally working
STA	MCU indicator, blinking when the MCU is normally working
TXD	TX indicator, lights up when sending data
RXD	RX indicator, lights up when receiving data
Left Ethernet port Green Indicator	Lights up when the connection of Ethernet Port 1 is established
Right Ethernet port Green Indicator	Lights up when the connection of Ethernet Port 2 is established
Left Ethernet Port Yellow Indicator	Lights up when the TCP connection is established
Right Ethernet Port Yellow Indicator	Data activity indicator, blinking when transmitting data

Supports Ethernet Port Cascade and PoE cascade power supply

Onboard 2-ch Ethernet Ports for communication and cascade Either one can be used for dual serial server network communication, while the other one can be used for cascading or communication with other devices

* Note: Each module in the cascade needs to be powered individually or using PoE cascade power supply. The maximum power consumption of a single module is 7W, please pay attention to the output power of Router when using PoE cascade power supply.

Relay connection

Contact rating of the onboard relay up to 10A 250VAC/30VDC

Enclosure Design

Rail-mounted ABS plastic enclosure, easy to install, safe to use
