RK-Wi.232DTS-FCC Rapid Development Kit User’s Manual © 2006 Radiotronix Inc, all rights reserved - 3 - 3/29/2006 1 Description The Wi.USB-DTS™ is a self-powered, standalone desktop transceiver based on the Radiotronix Wi.232DTS module. The unit draws its power from the USB port. 2 Wi.USB Setup • Install the USB driver in Windows. Do not connect the Wi.USB-DTS™ to your PC without first installing the driver. To install the driver, run the Silicon Laboratories CP210x UART to USB Bridge Driver as illustrated below. When the driver installation is complete, you may connect the Wi.USB-DTS™ unit to your PC. Windows will recognize the hardware and automatically install the driver for it. If Windows cannot find the driver for the CP210x device, you may have to locate it manually. The driver is unpacked to the subdirectory “\SiLabs\MCU\CP210x” in the root of your default drive when you first run the installation. • Using a USB cable, connect the Wi.USB-DTS™ to the PC. • IMPORTANT NOTE FOR HYPERTERMINAL USERS: See section 4.1
RK-Wi.232DTS-FCC Rapid Development Kit User’s Manual © 2006 Radiotronix Inc, all rights reserved - 4 - 3/29/2006 3 Using Wi.USB-DTS™ Evaluation Software The software supplied with the Wi.USB-DTS™ is used to read and set the volatile and non-volatile registers within the Wi.232DTS™ module contained within. Additionally, it provides a chat interface for basic information exchange. Please refer to the Wi.232DTS™ User’s Manual for more information on the register settings. 3.1 COM Port Setup and Selection. Upon starting the Wi.USB-DTS™ evaluation software, you will be presented with a COM port selection dialog box. Make sure that the Wi.USB-DTS™ unit is already connected to the computer via the USB cable before you start the software. This will ensure that the virtual COM port which is assigned to the USB to UART bridge controller by Windows is visible in the COM port selection list. Select the COM port used by the Wi.USB-DTS™ . If you need to find out which COM port this is, go to Control Panel > System Properties > Hardware Tab > Device Manager > Ports (COM & LPT) > CP2101 USB to UART. The first time you start the Wi.USB-DTS™ evaluation software, the Baud Rate should be left at 2400 baud, since this is the factory default baud rate setting for the unit. Tip: The Wi.USB-DTS™ evaluation software does not auto-detect the baud rate of the module. If you have changed the Non-Volatile Data Rate register, you will have to select the baud rate you set this register to when you start the Wi.USB-DTS™ evaluation software. 3.2 Wireless Chat Page. The Wireless Chat page in the Wi.USB-DTS™ evaluation software demonstrates the capability of the Wi.USB-DTS™ to be used as a wireless communications link. Wi.USB-DTS™ works as a wireless chat link with no register changes required, out of the box. To Use Wireless Chat: Type a message in the lower text field and press Enter. The text you typed will be displayed on the remote system, prefixed with a Node Identifier if you specified one.

The Non-Volatile Register page in the evaluation software allows you to change the default settings which will be loaded when the module is powered on. It is important to note that data rates in excess of 19.2kbps cannot be achieved in LP mode due to bandwidth limitations. Tip: If you change the Non-Volatile Data Rate setting, you will have to select this baud rate when you start the Wi.USB-DTS™ evaluation software. 3.4 Volatile Register Page In this page, you can change the Volatile settings of the module. Values programmed into these registers are lost of power-down. The page also provides a means of switching the receiver and transmitter on and off, setting receive and transmit channels, transceiver mode and modulation settings. It is important to note that data rates in excess of 19.2kbps cannot be achieved in LP mode due to bandwidth limitations.
RK-Wi.232DTS-FCC Rapid Development Kit User’s Manual © 2006 Radiotronix Inc, all rights reserved - 6 - 3/29/2006 4 Evaluation Software Functions 4.1 Setting Register Values. On both the Volatile and Non-Volatile pages, the registers are labeled by function. To set a register value, select the value from the options available for that register and click the “Write” button. To perform a read of that register, simply click the “Read” button. Descriptions of the register functions can be found in the Wi.232DTS™ User’s Manual. 4.2 Diagnostic Mode Commands There are a special class of commands available through the evaluation software. These controls are located on the “Volatile Registers” page as seen below. These commands place the module into special diagnostic modes that can be used to test the module’s performance, or to activate the transmitter for RF testing purposes. It is important to note that once a module executes a diagnostic command, it should be reset or have the power cycled to return to normal operation. 4.2.1 Transceiver Mode This selects the modulation mode and power output of both the transmitter and receiver. The mode is not set until “Set TX Diag” or “Set RX Diag” is pressed. If “Set RX Diag” is pressed, the power output value is ignored. 4.2.2 Transmit Diagnostic Transmit Diagnostic consists of four radio buttons which select the transmit channel. Low, Mid and High are quick reference buttons which can be used to select the lowest, the middle, or the highest channel. Any specific channel can be selected by using the controls below the “Set TX Diag” button. The “Set TX Diag” button switches the transmitter on using the channel and mode selected in the channel selector and transceiver mode controls. A “…1010101010101…” bit pattern is transmitted for bit error testing with another system or RF carrier analysis. 4.2.3 Receive Diagnostic Receive Diagnostic consists of four radio buttons which select the transmit channel. Low, Mid and High are quick reference buttons which can be used to select the lowest, the middle, or the highest channel. Any specific channel can be selected by using the controls above the “Set RX Diag” button. The “Set RX Diag” button switches on the receiver using the channel and mode selected in the channel selector and transceiver mode controls. Additionally, the module enters the diagnostic bit error test. If a “…1010101010101…” bit pattern is received at the frequency and baud rate set up in the relevant registers, the BER test will return the number and percent of bit errors. This information is displayed in the panel below the “Set RX Diag” button. If no transmission is present, or the transmission is at the wrong frequency or data rate, the module may enter an infinite loop waiting for the beginning of the data. In this case, the module should be powered down and back up to return the module to its normal operating mode.

HyperTerminal and many other terminal programs assert RTS by default. In the Wi.USB-DTS™, the RTS line is tied to the CMD pin on the module inside the Wi.USB-DTS™ . When the CMD pin is held low, which is the case when the RTS line is asserted, the module will be placed in command mode. In command mode, all UART data sent to the module will be interpreted as commands and will NOT be sent to the RF engine for transmission. Additionally, if a Wi.USB-DTS™ is powered on in the presence of an asserted RTS line, it will perform a full hardware and flash reset to the factory defaults. To use the Wi.USB-DTS™ with HyperTerminal or other terminal program, you must remove the cover, locate the jumper “JP2”, and remove it. Removing this jumper will disconnect the RTS line from the CMD pin on the Wi.232DTS™ module inside, allowing normal operation. It must be noted that while this jumper is removed, commands cannot be sent to the Wi.USB-DTS™ . Everything sent to the Wi.USB-DTS™ will be sent over RF.
