Welcome Signal strength indicators
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
Digi 6330-MX LTE Router User Guide
14
Welcome Signal bars explained
-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
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:
n Verify your SIM has been activated with your cellular operator.
n If 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.
n If 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.
n Try 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.
n Refer to Device status LEDs to use Digi 6330-MX indicator lights to aid in diagnosis.

Initial setup Physical installation
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:
n Ensure that the PSU is plugged into an AC power outlet and is receiving power.
n Ensure 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.

Network managed configuration
Your Digi 6330-MX has the capability to automatically sync and receive all settings from a centralized
cloud management tool, aView.
The aView management portal provides the following capabilities:
n Monitoring details including signal strength, network connectivity details (RSRP, CNTI, RSRQ,
Ec/Io, and so on), SIM card details (IMEI, IMSI, ESN, and so on), data transmitted/received, and
more.
n Email notifications based on connectivity, device firmware, and signal strength.
n Remote control.
n Out of band SMS recovery.
Devices using aView typically require no additional configuration or set-up.
Local configuration
If your Digi 6330-MX is not provisioned in aView, it will use a default local configuration profile which
will enable basic cellular connectivity (primary or backup) to your device.
To change any default settings for a Digi 6330-MX not provisioned in aView refer to Local device
management.

Initial setup Local device management
Local device management
Note Digi recommends you manage your device centrally using aView.
If you are not using the aView portal, you must manage and configure your device via the local
interface.
Connect to the device using its Gateway IP address 192.168.210.1 by default.
Username: root
Password: default
Once logged in via the local web interface, click on the Configuration link. You will initially be shown a
limited set of configuration options. Start by enabling local management of the device.
1. Uncheck box next to Enable central management.
2. (optional) If this is the first time the device has been configured, you will also need to update
the root user's password, under Users -> Root -> Password.
3. Click Save.
After saving the profile, the device will no longer attempt to sync with aView and a full range of
available configuration options will be visible. Clicking the down arrow next to the name of a
configuration option will display a pop-up providing help details about that option, including any
default values.
The local management portal offers the same configuration options as aView, although changes made
here will not sync with the cloud.
Note Passwords are case sensitive. (The default credentials are all lower case.)
Define a custom APN
If your device is unable to sync with aView because the device cannot establish a cellular connection
without a custom APN, it will need to be managed locally before remote configuration will be possible.
To do so:
1. Connect to the device's local UI by navigating to its default gateway address in a web browser.
2. From the Configuration tab, enter the name of the APN that should be associated with this
device.
3. Optional: If the custom APN requires a specific username and password, input those into the
corresponding fields.
4. Click the Save button to finalize any changes.
