5 Testing

It is important to test the unit connection to the network, the correct GPS
location, the unit status and inputs response before installing the unit in the
vehicle. In order to do this, you need to perform the following steps.

TCP test

This test verifies that the SIM card is open to the GPRS network, the unit can
connect to the network and make successful TCP/IP transmissions.
Press the TCP Test button (Communications > Advanced > Communication
Window > Configuration > Helios.1). Wait a few minutes until you receive a
pop-up window with a successful connection message.
If at the end of the TCP Test you do not receive a successful message, check
your APN settings (Helios Parameters > Network). Contact your cellular
provider and make sure the SIM card is open for GPRS. Verify that your SIM
card is not protected by a PIN code. If necessary, use a mobile phone to cancel
the PIN code.
You can also perform the test manually using the Terminal window. Open the
Terminal window (Communications > Advanced > Communication Window
> Configuration > Helios.1 > Open Terminal) and type the following
commands:
\tdm and press Enter (Modem mode). The modem will be turned on.
\tr and press Enter. This command runs a series of actions to check the
parameters such as reception level, visible networks and registered network,
SIM card state and information. It also attempts to connect to the routing
server. If successful, a "TCP: Send+" message will appear in the Terminal
window.
