This document contains information about the hardware included as part of a Laird OEM Transceiver System 
Developer Kit (SDK).  

The SDK is designed to allow flexibility at the hardware interface level so that the SDK can be interfaced to 
the OEM product, to a PC for performance testing, or to any other device that su5/3.3V TTL, RS232, 
RS485, or USB interface signals.  

The SDK is a complete, integrated package that contains all the hardware, software, and documentation 
needed to integrate an OEM transceiver quickly and simply.  

The SDK includes the following: 

 

SDK interface boards (2) 

 

AC power adapters (2) 

 

DB9 to DB9 cables (2) 

 

USB cables (2) 

 

Omni-directional dipole antennas with a 5” pigtail and MMCX connector (2) 
Other antennas are available for testing

SDK Board 

The SDK board is provided so the developer can use a standard PC interface to operate the transceivers and 
to aid in system integration. As shown in Figure 2 below, there are many features that enhance the 
functionality and usability of this board. It uses +5V TTL, RS232, RS485, and USB data formats for interfacing 
with the transceiver. The configuration and operation of the SDK board is continuously shown by the LEDs 
located on the edge of the board. See 

Table 1

 (Status LEDs) and 

Table 3

 (Switch and jumper settings) for 

definitions of the LEDs and switches.
