2: MDB1000
APCD-LM048-1.1 11
2.4 Turning the MDB1000 Off
The MDB1000 automatically shuts off if it is out of range of the EUM3006 for more than 60
seconds. You can tell if the MDB1000 is out of range, since the MODEM LED will go out as
well as all of the signal performance indicator LEDs. Only the ON/BATT LED will remain lit (or
flashing if the battery is low).
Pressing the ON button has no effect once the MDB1000 is on.
2.5 Interpreting the LEDs
There are 6 groups of LEDs:
ON/BATT
This LED has three states:
• ON - MDB1000 is working and batteries are good
• FLASHING - The batteries are low and should be replaced
• OFF - MDB1000 has turned itself off
MODEM
ON when the MDB1000 is receiving good data from the EUM3006. If the LED is OFF, then all
the remaining LEDs are OFF.
ETH
ON when the EUM3006 has an Ethernet link to the end-user PC or router.
SIGNAL STRENGTH
These 8 LEDs show the state of the EUM3006 if the MODEM LED is on. There are three
states shown:
1. No CCU - All the Signal Strength LEDs are OFF, indicating that the EUM3006 has
acquired a CCU but is not receiving any packets.
2. Auto CCU Discovery Mode - There are two LEDs ON in rotating patterns when the
EUM3006 is in Auto CCU Discovery mode and is searching for a CCU.
3. Normal Reception - If only one LED is ON, then the EUM3006 has registered with a
CCU and is receiving packets. The LED that is ON indicates the average received
Signal Strength Figure of Merit (FOM) for packets from the CCU. Ta b le 1 shows the
mapping between signal strength in dBm and the signal strength FOM.
