Serial Ports
Each serial port (RS-232 and RS-485) has an amber LED and a green LED that will
illuminate when that port is active. The amber LED (left) illuminates when the port is
transmitting data and the green LED (right) illuminates when the port is receiving data.
(Fig. 4-3)

VIANet Ports
The VIANet port LEDs function the same way as the serial port LEDs. The green (right)
LED indicates VIANet data is being received and the amber (left) LED indicates VIANet data
is being transmitted. (Fig. 4-4) The transmit (amber) LD should always be illuminated.
