1. Introduction
Thank you for purchasing the SRX1200 receiver. This document will help you set
up your receiver unit with the Microhard LTECUBE CAT4-Wifi Cellular Modem.
•The global version (LTECube-CAT4GL-WIFI) may be used anywhere.
•The North American version (LTECube-CAT4NA2-WIFI) may be used
only in North America.
2. Equipment Needed
You will need the following:
•1 Microhard LTECUBE CAT4-Wifi Modem
oList level 2 - 1.26 The cell modem must have a SIM card installed
that has been configured by the carrier to have a static IP address.
oThe static IP address is, supplied by the provider.
•1 Ethernet cable
•One (or more) SRX1200 receiver(s) to be set up.
Note: Only SRX1200-MD2 and SRX1200-D2 models are compatible for
remote connectivity. If you have a different model, and wish to
upgrade, please contact your Lotek representative.
•A USB-A to USB-B cable
•A Windows PC with the latest SRX1200 Host (henceforth known as
Host) installed.

3. Connections
To perform the setup, ensure that the following connections are made:
1. Connect the Microhard Cellular modem to the power cable provided
and connect this to a 120VAC or 220 VAC power adapter
2. Connect the Ethernet cable to the Microhard modem and the other
end of the cable to your PC.
Note: If the only available ethernet port on your PC is your network and internet
connection, then this procedure will have to be carried out while disconnected
from your network. If you can connect to your network via Wi-Fi, then this
problem can be avoided.
The first steps of this configuration involve setting up the Microhard Cellular
Modem itself. You do not need be connected to an SRX1200 Receiver during the
initial steps. Once you are ready to configure individual receivers, then you will
need to connect the receivers to the PC.
4. Cell Modem Configuration
The cell modem is supplied in a default state, with its Wi-Fi access switched off.
The only way to communicate with it is through an Ethernet cable connected
from the modem to a personal computer.
Before connecting any receivers, the modem itself requires a one-time initial
configuration using the SRX1200 Host.

4.1. Initial Configuration of Cell Modem
The SRX1200 receiver is not needed for this initial setup.
1. Ensure your modem has power, and is connected to your PC via
ethernet cable.
2. Launch the SRX1200 Host software on your PC.
3. Under the “Maintenance” tab of the SRX1200 Host, look for the “Cell
Modem” toolbar button.
Figure 1: To Begin Cell Modem Setup
4. This will launch the Cell Modem Setup Panel. If this is the first time a
modem has been setup on this system, it will look like Figure 2, below:

5. Enter a name for the modem, that will be make it recognizable to you. It
can contain spaces and some punctuation. This will allow the Host to
create a record of all your modem settings.

6. Click the “Save” button and a record will be created.
7. The IP Address will be automatically entered by the Host. This local IP
address (192.168.168.1) does not change.
a. Note that there is a checkbox, “Use Remote IP”. This should be
unchecked.

8. Clicking “Connect” will enable the “Sign On” button. The correct, case-
sensitive password must be entered. If this is a new modem, it will be
“admin”.
9. If successful, the right-hand side of the box should change to the box
below. Proceed to section 4.2.

4.2. Cell Modem Configuration in Host
1. Check the Instructions Tab. A list of steps is provided to help the user
ensure that all of the global modem settings are set correctly and what
to do before connecting the receiver.
a. The first of these is the administrative password.
2. To change the administrative password, select the “Admin Password”
tab. Enter your new password, and click “Change”. Upon returning to
the “Instructions” tab, it can be seen now that the “Admin Password”
item has been checked off.
b. Please record this password in a safe location, as it will be
needed to make future admin changes to your modem.
c. This is not to be confused with the Wi-Fi password, which is a
non-administrative password, and used to connect remote
devices to the modem’s Wi-Fi access point.
d. For security reasons, the modem will not allow a number of
key settings to be made unless the administrative password
has been set. The Host also enforces this.

3. The next unchecked item on the list is “Wi-Fi Password”. Go to the “Wi-Fi
SSID” tab.
4. A Wi-Fi SSID (network name) has been set by default. Both the Wi-Fi
SSID and the Wi-Fi password should be changed. Click “Set” once these
have been entered.
e. Once the user is ready to connect receivers, the Wi-Fi access
point must be enabled.
