12 SNB900 Radio Modem User Guide
3.1 Introduction
The SNB900 contains both a data modem and a radio. It can be used in
a variety of configurations to form a complete wireless data network.
For example, you can configure the SNB900 to operate as:
• a base radio modem, broadcasting directly to a Trimble MS750,
5700, 5800, R7, or R8 rover GPS receiver that contains an
internal radio modem
• a repeater
• an access point
3.2 Configuration
For a list of the settings that an SNB900 arrives with, see Default
settings, page 10. The default settings are stored in nonvolatile
memory and serve as the initial settings each time you start the radio
modem. Use WinFlash to reconfigure the settings as often as
necessary. You can also use the front panel menus to change some of
them.
32.1 Configuring the serial I/O port
To use WinFlash, connect the radio modem to a computer that is
running a Microsoft Windows 95, 98, Me, Windows NT® 4.0 or later,
Windows 2000, or Windows XP operating system.
Connect the SNB900 to the computer, install WinFlash, and configure
the serial I/O settings as described in the following sections.
Alternatively, configure the serial port communication settings from
the front panel, using the Data Port Config menu.
Note – The office computer must support a 38400 bps serial port data
rate.
