Testing a Standalone Unit
This section describes how to perform a C24 functionality test, whose purpose is to:
Introduce the user to the C24
•
Explain how to work with the C24 unit
•
Describe how to evaluate basic C24 features
•
The test setup provides a wide platform through which a C24 unit can be evaluated. The specific
test procedure described below covers only a few of the C24's many features. Using this setup,
you can perform several additional tests on the C24.
The test is performed using two modems, one of which is the C24. The modems communicate
with each other through a single computer, which also controls their operation.
The test requires knowledge about the operation of the C24 Developer's Kit, terminal
applications and AT commands. Refer to relevant documentation for assistance.
To perform the test, you need the following:
A C24 OEM cellular engine unit
