Revision Date Decription

A April

2020

Initial release the updated Digi 5400-RM Cellular Remote Manager User Guide for

firmware release 20.2:

nWith firmware release 20.2, Active Recovery has been renamed to Digi

SureLinkTM.

nAfter upgrading to firmware release 20.2, if a configuration erase is

performed, the Digi 5400-RM will default to Digi Remote Manager rather

than to aView.

See Important information about upgrading to firmware version 20.2.x for further

Exchanging power tips

The Digi 5400-RM may include four interchangeable plug tips that allow the Power Supply Unit (PSU)

to operate in most countries. The PSU comes with the United States style plug installed.

To change the plug tip:

1. While holding down the PUSH button, slide the current plug tip forward.

2. Pull off the attached plug tip.

3. Slide the new tip down into place until it clicks.

Signal

Strength

Standard 5-bar signal strength indication; a minimum of two bars is suggested for

reliable use.

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.

Welcome Initial setup

Digi 5400-RM Cellular Remote Manager User Guide 10

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

-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

1. Insert your activated SIM card provided by your cellular network operator. The metal contacts

should be facing down. You will hear a click once the SIM is completely inserted.

2. For maximum performance, attach both of the included antennas. While gripping the metal

connector section with your thumb and forefinger, tighten until secure. Do not tighten the

antenna by holding any part of the plastic antenna housing.

3. Connect the power supply unit to the device.
