CCT24
5.4 Developer’s Kit Default Operating Configuration
The default operating configuration of the CCT24DK developer’s kit is TDMA Mode 2, point-to-point, with
transparent serial data at 9.6 kb/s, 8N1. One CCT24 is preconfigured as a base and the other as a re-
mote. Labels on the bottom of the interface boards specify Base or Remote. The defaults can be overrid-
den 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 2 m (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 CCT24 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 shipped with the CCT24 radios and U.FL coax jumper cables installed in the interface
board. If a CCT24 radio and/or the U.FL jumper cable has been unplugged after receipt, confirm the
CCT24 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. 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.
