or a pass-through connection, is active. These LEDs can be used to see that a network cable
connection is made and when the DL100 transmits over the network.
Each RS-232 port has two LEDs associated with it (with the exception of I/O 2, which has three).
The left LED is a received data (RX) LED. The right LED is a transmitted data (TX) LED. The
TX LED is normally on and green when the unit is powered up. The RX LED is off when no
cable is connected to the serial port and green when a cable is connected and no data transfer is
taking place. When an RS-232 line is connected and idle, both the TX and RX LEDs will be lit
green. When data is transmitted, the TX LED quickly alternates green and red. These LEDs can
be used to verify that a cable is connected (the LED is lit) and that data is being transmitted or
received (the LEDs flicker between red and green). The CTS2 LED lights when a clear to send
signal is received on I/O2.
The DL100 has five LEDs to indicate file full status. A solid lit LED indicates the database
percentage is at or over the value for that LED. A blinking percentage full LED indicates the
database has less than the amount indicated by that LED, but more than the previous.
The Power LED has two operational states. Normally the power LED is lit steadily, with a short
blink once every ten seconds. This ‘heartbeat’ signal indicates typical operation. The second state
occurs during the boot sequence, where it will blink once every second until the boot sequence is
complete and two beeps are heard.
