Quick Start on a Point-to-MultiPoint Network
The following is a quick start guide for setting up two transceivers in Point-to-MultiPoint mode. This mode allows for a
Master to communicate with several Slaves simultaneously.
1. Connect the transceiver to the serial port of a computer either through a serial cable or via the diagnostics
cable. Make sure to connect the antenna port to a load and the radio to a power source (typically, 6 to 30
VDC).
2. Open up a HyperTerminal session.
• Use the following settings in connecting with HyperTerminal
• Connect to COMx (where 'x' is the number of the com port being connected to)
• Set data rate to -
19,200
, data bits -
8,
Parity-
none
, Stop bits –
1
, Flow control –
none
.
3. Press the
Setup
button on the radio. If using the diagnostics cable, press
Shift-U
(capital U).
• The three lights on the board should all turn green, indicating Setup mode.
• The main menu will appear on the screen.
4. Press
0
to get into the Operation Mode menu.
• Press
2
to set the radio as a point to
MultiPoint Master.
• OR, Press
3
to set the radio as a point to
MultiPoint Slave.
• Press
Esc
to get back to Main menu.
5. Press
1
in the main menu to change the Baud Rate.
• The baud rate must be changed to match the baud rate of the device that the radio is to be attached to.
• Press
Esc
to get back to Main menu.
6. At the Main Menu, press
3.
•
Set FreqKey, Max Packet Size, Min Packet Size, RF Data rate identical on all radios in the network.
Note:
Changing these values may help to eliminate interference from other FreeWave networks.
• Press
Esc
to get back to Main menu.
7. At the Main Menu, press
5
.
• Set the Network ID value to any value between 1 and 4095, except 255.
• Make sure this value is the same on every radio in the network.
