5.3 Developer’s Kit Default Operating Configuration
The default operating configuration of the DNT500DK developer’s kit is TDMA Mode 2, point-to-point, with
transparent serial data at 115.2 kb/s, 8N 1. One DNT500P is preconfigured as a base station and the
other as a remote. The defaults can be overridden to test other operating configurations using the DNT
Wizard utility discussed in Section 5.5. The default RF power setting is 0 dBm (1 mW), which is suitable
for side-by-side operation. The RF power level should be set higher as needed for longer range opera-
tion. Note that setting the RF power to a high level when doing side-by-side testing will overload the
DNT500P receiver and cause erratic operation.

5.4 Development Kit Hardware Assembly
Observe ESD precautions when handling the kit circuit boards. Referring to Figure 5.4.1, confirm each
DNT500P is correctly plugged into an interface board, with the radio oriented so that its U.FL connector is
next to the U.FL connector on the interface board. Check each 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 U.FL
jumper cables between the U.FL connectors on the radios and the interface boards. Then install the
dipole antennas. As shown in Figure 5.4.2, confirm there is a jumper on pins J14. The interface boards
can now be powered by the 9 V wall plug transformer power supplies (the interface boards can also be
run for a short time from the 9 V batteries for range testing, etc.).
