6.1Introduction

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.

6.3MTK 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). Commands are not case sensitive. All commands are of the form <command> space <command parameter>. For example ‘TC 20’. Table 6-1 on page 102 describes the serial port protocol in the PC to tester direction.
