Developer Kit User’s Manual
2. Hardware
2.1 SDK B
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.
