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, 8N1. One DNT500P is precon-
figured as a base station and the other as a remote. The defaults can be overridden to test
other operating configurations using the DNT500 Wizard utility discussed in Section 5.5.
The default RF power setting is 10 dBm, which is suitable for side-by-side operation. The
RF power level should be set higher as needed for longer range operation. Note that set-
ting 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 ori-
ented 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 anten-
nas. 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 inter-
face boards can also be run for a short time from the 9 V batteries for range testing, etc.).
