DR-TRC105-DK - 04/05/10
Introduction
The DR-TRC105 series development kits can be used to evaluate TRC105 radio
technology, and to prototype applications that will use the TRC105 RFIC. These
development kits include the necessary hardware, firmware and utility software to
support efficient TRC105 evaluation and system development. This user’s guide covers
the following development kits:

DR-TRC105 development kits are designed to facilitate the configuration of all TRC105
transmitter, receiver and interface functions, and to support application firmware and
system development. The development kits can be controlled using the RFIC Design
Assistant utility software. Two-way communication link testing is also supported by the
data terminal program built into the RFIC Design Assistant utility. In addition, a stand
alone range test function is included in the radio board firmware to allow roaming range
tests. Figure 1 shows a development kit interface board with a radio board installed.
Figure 1 - DR-TRC105-DK Radio and Interface Board Set
The antennas included in each development kit match the operating frequency of the
kit, and may be a different length than the 434 MHz antenna shown above. Antennas
should always be installed before turning on a radio board.

Figure 2 - DR-TRC105-DK Interface Board Connectors and Controls
Figure 2 shows the locations of the interface board DC power connectors, user controls
and LED indicators. Normally an interface board is powered from one of the 4.5 volt
universal wall-plug power supplies provided in the development kit, as shown in the left
panel of Figure 3. For roaming range testing and field testing, the interface board can be
powered from a 9 volt battery as shown in the right panel of Figure 3.
Note - do not
install a 9 volt battery while the interface board is connected to the wall-plug power
supply.
Use only one power source at a time. Power input pins are also provided for
connection to a regulated 4.5 to 12 volt lab supply. When connecting to these pins, take
care with the polarity. The pin closest to the power connector is the positive input.

The power switch shown in Figure 2 connects the output of the 3 volt regulator on the
interface board to the POWER ON LED, the serial communication interface circuitry and
the radio board. Note that there is a small current draw from the regulator when the
power switch is in the off position, and this will eventually discharge a 9 volt battery if it
is left installed.
The radio RESET button on the interface module allows the user to reset the radio
board to a know state from any mode the radio board is in.
Figure 4 - DR-TRC105-DK Interface Board Serial Connectors
Figure 4 shows the serial communication connectors on the interface board. The kit
includes two USB 2.0 A/B cables for connection to a PC. When a USB cable is plugged
into an interface board, it automatically disables the RS232 interface circuitry. Note that
the interface board is not designed to powered from the USB interface, so DC power
must be supplied separately as discussed above. The kit CD includes the PC drivers
needed to make the interface board USB connection appear as a virtual COM port.
Refer to the
USB Virtual COM Ports
section of the RFIC Design Assistant User’s Guide
on the CD for driver installation details.
To configure the interface board for RS232 operation,
remove
the serial jumpers shown
in Figure 4. Use a 9-pin “external modem cable” (straight through, not null modem) to
connect the interface board to the PC.
The left panel in Figure 5 shows USB operation, the right panel shows RS232
operation. Note the serial jumpers have been removed for RS232 operation.
