COMM and Fuse Alarm LED Indications

COMM
Fuse Alarm
The COMM LED indicates communication with the host. A red flash shows receive activity, while a green flash
shows transmit activity. A slow green blink represents a communication link idle for more than 2 minutes, which
is considered a communication failure. In addition, the front panel Fuse Alarm LED will show red if there is a
blown fuse.
