DNT90 Integration Guide - 08/09/12
8.4 Developer’s Kit Hardware Assembly
Observe ESD precautions when handling the kit circuit boards. When shipped, the DNT90EP radios and
U.FL coax jumper cables are installed in the interface boards, as shown in Figure 8.4.1. If a DNT90EP ra-
dio and/or the U.FL jumper cable has been unplugged after receipt, confirm the DNT90EP is correctly
plugged into its interface board with the radio oriented so that its U.FL connector is next to the U.FL con-
nector on the interface board, as shown in Figure 8.4.2. 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, screw each di-
pole antenna into and adaptor cable and “snap” the other end of the adaptor cable into the MMCX RF
connector on the development board as shown in Figure 8.4.2.

As shown in Figure 8.4.3, confirm there is a jumper on J10 (this jumper can be removed later and a
current meter connected across J10 to measure just the DNT90E’s current consumption during
operation).
Note: DNT90P is shown, DNT90PE application is identical.
