24 Vdc Power Supply Terminal Block

The Link150 gateway is powered by 24 Vdc or Power-over-Ethernet (PoE). We recommend a UL listed and UL recognized limited voltage/limited current or a Class 2 power supply with a 24 Vdc, 500 mA minimum.

NOTE: When the module is connected with both PoE and 24 Vdc and if 24 Vdc is removed, there is a temporary communication loss until the device gets power from PoE.

For 24 Vdc power supply connection, use copper conductor only.

RS232 Traffic LED

RS232 serial line traffic yellow LED indicates that the traffic is being transmitted or received over RS232 serial line network through the Link150 gateway. The LED blinks during the transmission and reception of the messages. Otherwise, the LED is OFF.

RS485 Traffic LED

RS485 serial line traffic yellow LED indicates that the traffic is being transmitted or received over RS485 serial line network through the Link150 gateway. The LED blinks during the transmission and reception of the messages. Otherwise, the LED is OFF.

IP Reset Pin

When the IP reset pin is pressed for 1 to 5 seconds, the IP acquisition mode is reset to the factory default (DHCP).

Factory Reset

When the IP reset pin is pressed for 10 to 15 seconds, all user-configurable information is reset to factory defaults.

Device Soft Restart Button

Press the device soft restart button for 10 to 15 seconds to soft restart the Link150 gateway. For more details refer to Troubleshooting section.
