DNT2400 - 08/18/09
5.4 Developer’s Kit Default Operating Configuration
The default operating configuration of the DNT2400DK developer’s kit is TDMA Mode 2, point-to-point,
with transparent serial data at 9.6 kb/s, 8N1. One DNT2400P is preconfigured as a base and the other as
a remote. Labels on the bottom of the interface boards specify Base or Remote. The defaults can be
overridden to test other operating configurations using the DNT Demo utility discussed in Section 5.5. The
default RF power setting is 0 dBm (1 mW), which is suitable for operation at a spacing of about 1.5 to 2 m
(4 to 6 ft). The RF power level should be set higher as needed for longer range operation. Note that
setting the RF power to a high level when doing testing at 2 m can overload the DNT2400P receiver and
cause erratic operation. See Section 5.3.
5.5 Developer’s Kit Hardware Assembly
Observe ESD precautions when handling the kit circuit boards. The components that make up a devel-
opment board are shown in Figure 5.5.1, and are shipped with the DNT2400P radios and U.FL coax
jumper cables installed in the interface board. If a DNT2400P radio and/or the U.FL jumper cable has
been unplugged after receipt, confirm the DNT2400P is correctly plugged into its interface board with the
radio oriented so that its U.FL connector is next to the U.FL connector on the interface board, as shown in
Figure 5.5.2. Also check the radio’s alignment in the socket on the interface board. No pins should be
hanging out over the ends of the connector. Next, install the dipole antennas.
