Suggested production tests
Consider the following tests when you design your production test procedures for
devices with the AirPrime module installed.
• Visual check of the module's connectors and RF assemblies
• Module is operational
• USB connection is functional
• LED is functional
• W_DISABLE_N (module power down)
• Firmware revision check
• Rx tests on main and auxiliary paths
• Tx test

Production test procedure

The following is a suggested test plan — you must decide which tests are
appropriate for your product. You may wish to add additional tests that more fully
exercise the capabilities of your product.
Using an appropriate Dev Kit-based test station, and referring to the appropriate
AT command references:
1. Visually inspect the module's connectors and RF assemblies for obvious
defects before installing it in the test station.
2. Ensure that the module is turned off before beginning your tests — Drive
W_DISABLE_N low.
3. If using Linux, determine if any USB devices are currently connected to the
computer:
a. Open a shell window and enter the command
b. Record the ttyUSBn values that are returned; these are the currently
connected USB devices. If the command returns "no such file or
directory", there are no devices currently connected.
4. Test W_DISABLE_N — Turn on the module by letting W_DISABLE_N float
(high impedance).
5. Test USB functionality — Check for USB enumeration.
· (Windows systems) The Device Manager shows Sierra Wireless items
under Ports (COM & LPT). The devices shown depend on the module type.
]
For example:
· (Linux systems) Enter the command
compare the results with those from
devices, then the modem has enumerated successfully. (There should be
seven new devices) For example:
ls / dev / tty / USB*
ls / dev / tty / USB*
and then record and
Step 3. If there are any new ttyUSBn
