Introduction
The Manufacturing Test Kit (MTK) provides production line test support in addition to providing FCC
certification tests. This section provides a description of the Tester serial protocol, the RF protocol
between the MTK Tester and the MTK Device-Under-Test (DUT) and a brief description of porting
the MTK DUT code to different platforms.
Refer to the Manufacturing Test Kit User's Guide for instructions on operating the MTK Tester.

MTK Serial Protocol
The MTK Tester implements a text-based protocol over an RS232 serial port to provide both a con-
figurable standard test and script-based testing.
All commands listed under the standard test set a configuration value that is stored in non-volatile
storage. All remaining serial commands only affect the current setting and are not stored (reset
across power cycles). Table A.4-1 describes the serial port protocol in the PC to tester direction.
