8 StarLink SLE-MAX2-FIRE Commercial Series Sole/Dual-Path Alarm Communicator -- Installation Instructions
RADIO PCB "DUAL SIM" OVERVIEW
To enhance communication reliability, the StarLink communi-
cator is equipped with two network carrier SIM card slots (for
Verizon and AT&T) and is configured to automatically to use
the carrier with the strongest signal. Fully activated from the
factory, the network carrier SIM slots are configured using the
www.NapcoNoc.com Radio Carrier screen (select Checkins
> Dual SIM Signal). Various LEDs on the communicator PC
boards also provide visual indications, described below.
When the communicator is powered, the unit performs its
standard "Checkin" with the NAPCO NOC using the carrier
indicated by the lit LED located next to its SIM card slot. Five
minutes after power up (this is the Scan Delay After Power
Up NOC default setting, described below) the unit scans each
SIM slot carrier, collecting and comparing various network
signal quality parameters and selects the carrier with the best
signal quality. During the scans, the yellow LED (D4) on the
main PC board will flash at the rate of one second on, one
second off.
The communicator will continue to use the selected carrier
provided low noise/high signal strength communication is
maintained. When the Scan Periodicity NOC selection ex-
pires (after 7 days by default), another scan and carrier selec-
tion will occur. The Radio Carrier NOC screen will be updat-
ed with a signal data entry report describing the scan results
after every scan.
The following feature settings are provided in the NOC Radio
Carrier screen to accommodate these two network SIM card
slots:
Scan Delay After Power Up
By default, an initial signal scan of both slots automatically
occurs 5 minutes after powering the unit; you can set the scan
delay via the drop down menu for "NO Initial Scan", 5 and 15
minutes (select "NO Initial Scan" if no initial scan is desired).
Note: When a scan is in progress, the yellow LED (D4) on
the main PC board blinks at the rate of one second on, one
second off. After the signal scan of both slots occurs, the Ac-
tive Slot is then selected based on the stability of the cellular
network connection and the better signal quality (based on
both the average power received from a single signal and sig-
nal-to-noise ratio factors).
Scan Periodicity
Recurring automatic SIM slot scans can be set with this drop-
down menu: "Turn OFF Scanning" and "7 days" (default).
An automatic scan will occur every 7 days unless "Turn OFF
Scanning" is selected.
The NOC Radio Carrier screen also includes the following
buttons:
Scan SIMs
Select to manually start a SIM scan.
Switch SIM
Select to manually switch from one SIM card slot to the other
slot. Note: Alternatively, if the radio PC board includes a mo-
mentary pushbutton, press/release this button to manually
switch from one SIM slot to the other slot. This button functions
in the same way as this Switch SIM button in the Radio Carri-
er screen.
Get SIM Status
Click to request the current status of both SIMs. The results of
each status request are displayed in the Radio Carrier screen
(see example image on this page). Each row displays specific
dual SIM signal information sent from the StarLink communica-
tor after every scan, every switch slot request, and after every
status request. The columns in this table include:
• Received Time: To determine transmission order, this is
the timestamp the signal was received (displayed as YYYY-
MM-DD HH:MM:SS in 24-hour notation)
• SIM1/SIM2 ICCID: Used for tracking, the ICCID (Integrated
Circuit Card ID) is a unique identification number assigned
to the specified SIM card in the radio PC board
• SIM1/SIM2 IP address: IP address assigned to the SIM by
the carrier
• Carrier: Displays the previous column's carrier name
• RSSI/Blinks: RSSI (Received Signal Strength Indicator)
