3.8 LED Status
The LED provides the RIO-2015PG operation information. The LED status is described as follow:
Power LED:
Power LED keeps ON if power (+9VDC to +48VDC) is correct.
Ready LED:
Ready LED keeps ON when RIO-2015PG firmware is ready for operation.
LAN LED:
Link and Activity LED will turn ON when the Ethernet cable is connected. When there
is network data traffic, this LED will flash.
LED 1:
This LED is dual color and it indicates the serial data traffic of RS-485, RS-232 and serial
