Testing a Standalone Unit 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 • A C24 Developer's Kit • A desktop or laptop computer, which includes: - A free serial communications port (RS232) - A connected and active line modem (internal or external) - A terminal application (such as HyperTerminal) Test Setup To Setup the C24 Test Follow this procedure (Figure 5-1) to set up your equipment before performing the test: 1. Verify that the computer you intend to use for the test is equipped with a working line modem You can use a second C24 unit instead of the line modem. When doing so, you must repeat the setup procedure that follows for the additional C24. 2. Set up the C24 and the Developer Board as described in "Initial Setup" in "Chapter 2: Developer Board and Interfaces Description" in the "C24 Developer's Kit" (Motorola part no. 6802985C53) 3. Verify that the C24 has adequate reception from the local network 4. Connect the Developer Board's RS232 port to the computer's serial port 5.

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
•
A C24 Developer's Kit
•
A desktop or laptop computer, which includes:
–
A free serial communications port (RS232)
–
A connected and active line modem (internal or external)
–
A terminal application (such as HyperTerminal)
Test Setup
To Setup the C24 Test
Follow this procedure (
Figure 5-1
) to set up your equipment before performing the test:
1.
Verify that the computer you intend to use for the test is equipped with a working
line modem
You can use a second C24 unit instead of the line modem. When doing so, you must repeat
the setup procedure that follows for the additional C24.
2.
Set up the C24 and the Developer Board as described in
“Initial Setup”
in
“Chapter 2:
Developer Board and Interfaces Description”
in the
“C24 Developer’s Kit”
(Motorola part no. 6802985C53)
3.
Verify that the C24 has adequate reception from the local network
4.
Connect the Developer Board’s RS232 port to the computer’s serial port
5.
Open a terminal application window (such as HyperTerminal) and configure it to operate
with the serial port occupied by the
C24
