Description and Operation
Getting Started
JLink LTE is a family of devices designed for or-
ganizing a local network between dierent devices
via WiFi, Ethernet, and Bluetooth, connecting to the
Internet using 4G cellular digital communication ser-
vices.
Figure 1. JLink LTE
JLink LTE provides a robust solution linking the field
GNSS equipment to RTN, where no cell phone cover is
available. JLink LTE devices may contain 1 W either
UHF (406 to 470 MHz) or VHF (138-174 MHz), or ISM
license free USA band (902-928 MHz) and European
CEPT license free (868-870 MHz) radio transceiver.
Marine Radiobeacon receiver (283.5 to 325 kHz) can
be built-in into JLink LTE device.
JLink LTE can be configured and supported using
web-interface through Internet, and this makes the
setup mechanism simple and accessible from any-
where in the world.
JLink LTE LED Functionality
The table below describes the LED indicators and
device state:

www.javad.com 9
Installation
1. Connect Bluetooth and GSM antennas to JLink
LTE as shown on the picture below.
2. Connect JLink LTE to external power supply
(10…30 V).
3. Insert SIM card to the SIM card slot if you would
like to use GSM connection to connect to Internet.
Figure 2. SIM card installation
4. Plug in LAN cable if you would like to use Ethernet
connection to connect to Internet.
5. Plug in COM PORT cable if you would like to use
CLI interface to communicate with device.
Setup and Configuration
1. Turn on power of JLink LTE.
2. Wait for complete loading. When it is complete,
Power LED will blink.
3. Connect to the device and configure it using
web-browser.
Connection can be established in one o the follow-
ing ways:
• via Bluetooth interface: the device (PC, hand-
held/pad) should be with Bluetooth interface with
PAN profile support. JLink LTE Bluetooth-interface
is in visibility mode, has the name “ Jlink LTE ” and
PIN code 0000 . When connection is established
open the web-browser and enter the address
10.1.11.1:8080 .
• via WiFi interface: The device (PC, handheld/
pad) should be with WiFi interface. JLink LTE Wi-
Fi-interface has the name “ Jlink LTE ” and pass-
word “ testtest ”. When connection is established
open the web-browser and enter the address
10.1.10.1:8080.
• via Ethernet: JLink LTE LAN static IP adress is
192.168.0.200 and network mask is 255.255.255.0.
On the PC connected to the same LAN, open
the web browser and enter the address
192.168.0.200:8080 . The dialog window appears
with login/password request. Enter login and pass-
word ( jlink/jlink ).

...Configure TRIUMPH-2 and JLink LTE
to provide TRIUMPH-2 services through
Internet
In this configuration JLink LTE will share its Internet
connection (established using the GSM interface)
with the TRIUMPH-2 receiver connected to JLink LTE
as a WiFi client.
1. Connect to Jlink LTE via web interface.
2. GSM configuration:
• In the Communication/GSM tab set the APN pa-
rameters (if necessary) and insert the SIM card to
its slot.
Note: Ensure the SIM card provides the Static IP.
• In the Communication/Power Management tab
activate the GSM interface and wait for registering
in the network and Internet access availability. The
detailed connection status can be checked in the
Status/GSM tab.
Figure 23. GSM configuration tab
3. Setup WiFi configuration:
• In the Communication/WiFi tab click on Set AP
mode to switch the interface to the AP mode and
set following AP parameters: SSID(WiFi Acsses
pointname), Protection (WPA2) and Security pass-
phrase (“password”) .
• In the Communication/Power Managment tab
turn the WiFi on.
The detailed connection status can be checked in the
Status/WiFi tab.
The JLink LTE provides the port forwarding mecha-
nism from internet (GSM interface) to WiFi clients.
Port forwarding mechanism works in a following way:
JLink LTE receives data from internet and redirects it
to its WiFi clients. Data packets received by 1110-1119
ports will be redirected to Wi-Fi client which IP ad-
dress is 10.1.10.110.
Data packets received by 1120-1129 ports will
be redirected to WiFi client which IP address is
10.1.10.120. To receive the redirected data of JLink
LTE the TRIUMPH-2 receiver should be connected to
JLink LTE through WiFi interface and TRIUMPH-2’s IP
address should be set 10.1.10.110 or 10.1.10.120.
Note: The default gateway is 10.1.10.1.
Figure 24. WiFi configuration tab
The TRIUMPH-2 configuration steps are the follow-
ing:
1. Connect TRIUMPH-2 to PC via USB or Bluetooth
interface and start NetView.
2. Click Connection, select the connection using
port, specify the COM port the receiver is connected
to. Click Connect to connect to the receiver.
Figure 25. NetView connection tab
