RK-Wi.232DTS-FCC Rapid Development Kit User’s Manual 3 Using the RK-Wi.232DTS-FCC Evaluation Software The software supplied with the RK-Wi.232DTS-FCC RadKit is used to read and set the volatile and non-volatile registers with the Wi.232DTS module. Refer to the Wi.232DTS Users Manual for more information on the register settings. 3.1 COM Port Setup and Selection. Upon starting the RK-Wi.232DTS-FCC evaluation software, you will be presented with a COM port selection dialog box. If you are using the USB interface, make sure that the evaluation board 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. The first time you start the RK-Wi.232DTS-FCC evaluation software, the Baud Rate should be left at 2400 baud, since this is the factory default baud rate setting for the module. Tip: The RK-Wi.232DTS-FCC evaluation software does not autodetect 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 RK-Wi.232DTS-FCC evaluation software. 3.2 Wireless Chat Page. The Wireless Chat page in the RK-Wi.232DTS-FCC evaluation software demonstrates the capability of the Wi.232 to be used as a wireless communications link. The Rapid Development kit 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. © 2002-5 Radiotronix Inc, all rights reserved - 4 - 11/7/2005
RK-Wi.232DTS-FCC Rapid Development Kit User’s Manual 3.3 Non-Volatile Register Page. 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 the baud rate you set this register to when you start the RK-Wi.232DTS-FCC 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. © 2002-5 Radiotronix Inc, all rights reserved - 5 - 11/7/2005
RK-Wi.232DTS-FCC Rapid Development Kit User’s Manual 4 Using the Evaluation Software 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 Users 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. © 2002-5 Radiotronix Inc, all rights reserved - 6 - 11/7/2005
RK-Wi.232DTS-FCC Rapid Development Kit User’s Manual 5 Notes 5.1 Microsoft Windows / Hilgraeve HyperTerminal The RK-Wi.232DTS-FCC Evaluation Kit can be used with HyperTerminal to receive and transmit RS-232 data and send files using file transfer protocols such as ZMODEM. HyperTerminal and many other terminal programs assert RTS by default. On the evaluation board, the RTS line is tied to the CMD pin on the module. 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 an evaluation board is switched 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 evaluation board with HyperTerminal or other terminal program, you must first remove the jumpers from pins 7+8 of JP2, if you are using an RS-232 connection to your PC, or JP3, if you are using a USB connection to your PC. Removing this jumper will disconnect the RTS line from the CMD pin on the module, allowing normal operation. 5.2 Loopback Mode The RK-Wi.232DTS-FCC kit can be operated in a loopback mode by configuring the COM jumpers in such a way as to link together the TXD and RXD lines to and from the module in the remote evaluation board. Using this mode, the user can send data from their local evaluation board and have it re-transmitted back to them by the remote evaluation board. The maximum baud rate allowed in loopback mode is 38400 baud for point to point communications only. Loopback mode using the RS232 jumpers: © 2002-5 Radiotronix Inc, all rights reserved - 7 - 11/7/2005
