Objective

This procedure will be used to setup and configure Freewave Radio Modems.

Scope

The procedure provides steps for the setup and configuration of a pair of Freewave radio modems in what is refered to as point to point communications.

Responsibilities

This steps in this procedure should only be completed by PSMFC personnel during installation or troubleshooting of radio communications.

Procedure

The following procedure information is also available in the Spread Spectrum Wireless Data Transceiver User Manual Version 6.1 provided by FreeWave Technologies Spread Spectrum Wireless Data Transceiver User Manual

Note: The terms Modem and Transceiver are used interchangeably in this manual and in the text of the Setup menu. While the words have different meanings, the two terms should be treated as one and the same when referring to FreeWave products.

Note: Included on the User Manual CD is the optional “EZConfig” transceiver setup program and instructions. This program eliminates the need to use HyperTerminal to program the transceivers.

Note: If you are running Vista as an operating system than you will not have Hyperterminal, you can download this .zip file and place the .exe and .dll files anywhere in your system. To execute hyperterm you will need to just double click on the executable to run. Hyperterm.zip

PC Connection

Hyperterminal

Once the transceiver is powered and connected with the programming cable to the programming computer, it can be programmed for use through HyperTerminal or EZConfig. The following describes how to set HyperTerminal to program the transceivers. Accessing HyperTerminal’s Setup Menu Note: The following screen shots are taken from a computer using Windows XP. The display may vary slightly if using different operating systems.

1. Click on the Start button. A cascading menu appears. Select Programs, Accessories, Communications and then HyperTerminal. A window appears similar to the following:

1. Double­click on the Hypertrm.exe icon.

1. In the Name text box, type in a descriptive name. Select an icon from the Icon selection box.
2. Click on the OK button. The following “Connect To” dialog box appears.
3. Select the connection type to be used from the Connect using drop­down menu. In most cases the connection type will be either Direct to Com1 or Direct to Com2.
4. Click on the OK button. The Properties dialog box appears for the selected connection type.

1. The following are the port settings which must be set for a proper connection:

Port Setting	Menu Options to Select
Bits per second	19200
Data bits	8
Parity	None
Stop bits	1
Flow control	None

1. After selecting the appropriate menu items for each setting, click on the OK button. The following HyperTerminal dialog box appears:

1. To connect HyperTerminal to the transceiver, press the Setup button on the back of the FreeWave transceiver. If connected to the diagnostics port, type U (Capital ‘U’) to invoke the Setup menu.

• When Setup is invoked, the FreeWave Setup Main Menu will display in the HyperTerminal dialog box. All three LED’s on the transceiver will light green ... and stay green as long as the transceiver is in the Setup mode.

1. Save the HyperTerminal connection settings by selecting Save from the File menu.

IMPORTANT NOTE: Whenever a change is made to the HyperTerminal settings in an open terminal session, the connection must be disconnected then reconnected before the settings will take effect. Connecting and Disconnecting from HyperTerminal The HyperTerminal dialog box displays several icons in the toolbar. To reconnect to HyperTerminal, click on the Disconnect icon, and then click on the Call icon to reconnect. If the settings have not been saved they must be reselected when HyperTerminal reconnects to the transceiver.

EZ Config

1. Attach the serial cable provided with modem, this cable attaches to the computer serial port and the diagnostics port on the back of the modem, or a standard RS-232 cable.
2. Insert the CD provided by FreeWave and select the EZConfig icon.
3. Once the program has started push the Setup button on the back. Verify that all three LED's are green.
4. On the EZConfig page select the Read From Radio button.
5. The information that has been programmed into the modem will now be displayed. You will be able to instantly verify the modem serial number and firmware version on the top of the page.
6. After the modem has been verified you will need to push the Setup button again before continuing with the configuration of the modem.

Modem Configuration

• The modems that are installed at Prosser are setup as a Point-to-Point radio system. This means that each set consists of a master and a slave that only communicate with each other. This configuration was selected to minimize potential losses of power and failures of the equipment.
• The master modems are located in the Juvenile facility and the slaves reside at each ladder location. There are many parameters whether you select to use the Hyperterm or EZConfig, but not all parameters pertain to the Point-to-Point settings. This procedure will only address the settings used for the Prosser installations. The settings listed below are from the EZConfig tabs but the same settigns are used in the Hyperterm connection but the navigation is a little different.
• Any questions on other settings can be answered in the Spread Spectrum Wireless Data Transceiver User Manual. You will need to program both modems (Master and Slave) before you will have a link between the modems. A solid link is identifiable by the color of the front panel LED's. The Carrier Detect (CD) will be a solid Green and the Transmit (TX) and Clear to Send (CTS) will intermittently flash Red .

Note: Remember to ensure that the modem is in the program (setup) mode before starting your programming. The modem is in program mode when all three LED's are solid Green .

Set Operation Mode

1. Make the selction to get to this section.
2. Select either 0 (Point to Point Master) or 1 (Point to Point Slave). You can ignore the Ethernet options as they do not apply.

Set Baud Rate

1. Make the selection to get to this section.
2. Set baud rate to 155,200.
3. Set data type to RS232.
4. Set flow control to None.
5. Set Data and Parity to 8-none-1.
6. Set Turn On Delay to 0 (default).
7. Set MODBus RTU to 0 (default).
8. Set Turn Off Delay to 0 (default).

Transmission Characteristics

1. Set the Frequency Key to 5 or 6. The frequency Key allows the hopping patterns to be different to minimize interference of other transceivers operating in close proximity. At Prosser we are using these two settings for each set of antennas that are on a mast, for example transceiver 01 has a frequency key of 5 and transceiver 02 has a frequency key of 6.
2. Set the Hop Table Version to Standard or Australia. The hop table allows the user to choose the portion of the band in which the transceiver will operate. This in conjunction with the frequency key will help to minimize any interference between radio modems.
3. Set the Hop Table Size to 112 (default).
4. Set the Hop Freq Offset to 0 (default).
5. Set the Max Packet Size to 8 (default).
6. Set the Min Packet Size to 9 (default).

Note: The settings for the Max and Min Packet sizes are the same on all transceivers with the exception of 03. The settings were changed to resolve a communications problem that was occuring on a random basis with this system. The error was causing Minimon to report a communications error and the only way to clear the error was to stop the Minmon application and re-start the application. The current settings for transceiver 03 are Max Packet Size 0 and Min Packet Size 9 which were suggestions made by FreeWave technical support.

1. Set Lowpower Mode to 0 (default).
2. Set Transmit Power to 5. The power was turned down because of the close proximity of the antennas (less than 1/2 mile line of sight).
3. Set Remote LED to 0 (default).
4. Set RTS to CTS to 0 (default).
5. Set the Retry Timeout to 255 (default).
6. Set the Slave Security to ON (default).
7. Set the High Noise to OFF (default).
8. Set the RF Data Rate and MCU Speed to Normal (default).
9. Set the Transmit Rate to 1 (default).

Call Book

The call book section refers to the transceiver serial number that should communicate with the transceiver that is being programmed. Since we have set are systems to be a Point-to-Point system the call books only have the serial numbers of the cooresponding transcievers that are necessary.

1. Enter the serial number of the transceiver which you wish to communicate with.
2. Make sure that you select the radio button of that transceiver or if you only have one serial number listed you can select Call All.

Program Radio

• After all the selections have been chosen and all the LED's on the front of the transceiver are solid Green you can select Program Radio (EZConfig) or hit ESC (Hyperterminal) to program the transceiver.

• Once the program is complete verify the settings by pushing the setup button and selecting Read From Radio (EZConfig) or typing U(Hyperterm Connection).
