to establish an Internet connection either through its cellular modem or the ethernet port .
1. Indicator lights on the Wireless Strength Indicator show you the cellular network signal
strength.
2. The power LED confirms the unit is receiving electricity.
3. Cellular connectivity status is indicated by the color-coded LTE light.
4. Ethernet connections are confirmed via the light corresponding to the Digi 6330-MX port
number.
LTE status indicators

Welcome Signal strength indicators
Digi 6330-MX LTE Router User Guide 14
Signal strength indicators
The weighted dBm measurements are negative numbers, meaning the smaller negative values
denote a larger number. So, for example, a -85 is a better signal than -90.
Note For more information regarding how signal strength is calculated and subsequently displayed via
the LED indicators, refer to Signal bars explained.
Signal bars explained
The LTE signal status bars are calculated using various algorithms based on the network type it is
connected to. For 4G LTE, the RSRP, SNR, and RSSI values are all factored in to determine the
reported signal strength bars. For 3G networks (including HSPA+) and 2G networks, the signal
strength bars are determined by the RSSI value.
4G LTE algorithm
Determine RSRP, SNR, and RSSI values separately, using the following
RSRP > -85, rsrp_bars=5
-95 < RSRP <= -85, rsrp_bars=4
-105 < RSRP <= -95, rsrp_bars=3
-115 < RSRP <= -105, rsrp_bars=2
-199 < RSRP <= -115, if we're connected to the cellular network, rsrp_bars=1,
if not rsrp_bars=0
If RSRP <= -199, then use RSSI as the value and run it through the same algorithm described above.
SNR >= 13, snr_bars=5
4.5 <= SNR < 13, snr_bars=4
1 <= SNR < 4, snr_bars=3

Welcome Signal bars explained
Digi 6330-MX LTE Router User Guide 15
-3 < SNR < 1, snr_bars=2
-99 < SNR <= -3, if we're connected to the cellular network, snr_bars=1, if not
snr_bars=0
Once the snr_bars and rsrp_bars are determined, use the lesser of the two. That is the reported
signal strength bars.
3G algorithm
Determine RSSI signal strength.
RSSI > -80, bars=5
-90 < RSSI <= -80, bars=4
-100 < RSSI <= -90, bars=3
-106 < RSSI <= -100, bars=2
RSSI <= -106, if we're connected to the cellular network, bars=1, if not bars=0
bars is then reported as the signal strength bars.
2G algorithm
Determine RSSI signal strength.
RSSI > -80, bars=5
-89 < RSSI <= -80, bars=4
-98 < RSSI <= -89, bars=3
-104 < RSSI <= -98, bars=2
RSSI <= -104, if we're connected to the cellular network, bars=1, if not bars=0
bars is then reported as the signal strength bars.

Initial setup Site survey
Digi 6330-MX LTE Router User Guide 17
Site survey
A cellular site survey is not necessary if your anticipated installation location is known to have strong
cellular signal strength. If you are unsure of available cellular signal strength or are choosing between
several installation locations, follow the below instructions to perform a site survey to determine your
best possible installation location. After the optimal location has been determined, set up the Digi
6330-MX with either the power supply unit or the PoE injector cable.
1. During a site survey it is useful to use the included battery pack instead of the power supply
unit to power the Digi 6330-MX. The battery pack will power your device for approximately two
hours while you perform your site survey. The battery pack is not rechargeable and should be
properly disposed of after use.
2. Move the Digi 6330-MX to different locations within your site to determine the best
compromise between signal strength and installation constraints. Since cellular signal strength
may fluctuate, it is important to wait at each location for 1 minute while observing the signal
strength indicator on the front of the device. Minimum cellular signal strength for proper
operation is 2 bars.
3. After the optimal location has been determined, remove the battery pack and connect either
the main power supply unit or PoE injector cable (see Physical installation).
Note After the optimal location has been determined, set up the Digi 6330-MX with either the power
supply unit or the PoE injector cable.
Site survey troubleshooting
If you are unable to verify a location with a strong cellular signal:
nVerify your SIM has been activated with your cellular operator.
nIf cellular signal isn’t indicated on the Digi 6330-MX indoors, then take the device outdoors to
verify that your cellular network operator has coverage in your location.
nIf the outdoor cellular signal strength is less than 2 bars, it may be necessary to connect using
a different cellular network operator. This requires an activated SIM from the alternate cellular
network operator.
nTry the device/antennas in different orientations and away from other nearby electronic
equipment at each test location.
Note LTE requires the use of both antennas & antennas will usually give better performance
when vertical.
nRefer to Device status LEDs to use Digi 6330-MX indicator lights to aid in diagnosis.

Initial setup Physical installation
Digi 6330-MX LTE Router User Guide 18
Physical installation
Connecting to the site network with local power
1. Plug the power supply unit into an AC power outlet
2. Connect the PSU to the Digi 6330-MX.
Connecting to the site network with remote power
If your device needs to be positioned some distance from either the nearest AC power outlet or site
network equipment, using the included passive Power-over-Ethernet (PoE) injector will simplify the
installation cabling and allow for improved cellular signal strength. The POE injector cable allows the
DC power and Ethernet connection to be run to the Digi 6330-MX via the Ethernet connection only.
1. Plug the power supply unit into an AC power outlet and connect to the PoE injector.
2. Connect an Ethernet cable from the RJ45 socket/jack on the PoE injector, (marked POE), to
the Ethernet port of the device.
3. Run another Ethernet cable from the PoE injector LAN port to the client device that will be
associated with the Digi 6330-MX first Ethernet port (marked 1/POE).
Remote power trouble shooting
The LED marked IN will illuminate when the PoE injector is receiving power from the PSU. The LED
marked OUT lights up green when an Ethernet connection is recognized by the Digi 6330-MX.
If the IN LED is not illuminated check the following:
nEnsure that the PSU is plugged into an AC power outlet and is receiving power.
nEnsure that the PSU power plug is correctly connected to the POE injector cable power input
socket.
If the OUT LED is not illuminated after connecting to the Digi 6330-MX, verify the integrity of the
Ethernet cable.
Note The PoE injector must be connected to LAN port 1 on the Digi 6330-MX for the device to properly
receive power.
