CCT24
There are three serial connectors on the interface boards. The RJ-45 connector provides a high-speed
RS232 interface to the CCT24’s main serial port. The USB connector provides an optional interface to the
radio’s main serial port. The RJ-11 connector provides a high-speed RS232 interface to the radio’s diag-
nostic port. The DNT Demo utility program runs on the radio’s main port.

Many desktop PCs have a built-in serial port capable of operation at 9.6 kb/s. The kit can be run satisfac-
torily at the 9.6 kb/s data rate, but not at its fastest throughput. Use the RJ-45 to DB-9F cable assemblies
for serial port operation.

Optionally, the kit development boards can be run from USB ports. Plugging in the USB cable automati-
cally switches operation from the RJ-45 connector. The USB interface is based on an FT232RL serial-to-
USB converter IC manufactured by FTDI. The FT232RL driver files are located in the i386 and AMD64
folders on the kit CD, and the latest version of the drivers can downloaded from the FTDI website,
www.ftdichip.com. The drivers create a virtual COM port on the PC. Power the Base using one of the
supplied wall-plug power supplies. Next connect the Base to the PC with a USB cable. The PC will find
the new USB hardware and open a driver installation dialog box. Enter the letter of the drive holding the
kit CD and click Continue. The installation dialog will run twice to complete the FT232R driver installation.

5.6 DNT Demo Utility Program
The DNT Demo utility requires only one PC for initial kit operation and sensor applications (ADC, PWM
and digital I/O). Two serial/USB ports are required for bidirectional serial communications. Section 5.6.1
below covers using the DNT Demo utility for initial kit operation and familiarization. Section 5.6.2 covers
serial message communication and radio configuration.
