mW. The USB is 2.0 Full Speed compatible, thus providing for COM Port data rates between 9,600
to 115,200 BPS as required by the Gridstream S4SBR LPP port.
USB Cable Installation
NOTE: Before using the USB cable the first time, confirm that the PC’s Internet connection is active.
Connect the device to a spare USB port on your PC. The Microsoft composite device driver is
automatically loaded in the background. Once the composite driver has been installed, the Windows
Found New Hardware Wizard dialog will launch.
The installation process may continue by installing the USB Serial Converter driver for a second
port of the USB Cable. The procedure for installing the second port is identical to that for installing
the first port from the first screen of the Found New Hardware Wizard.
Antennas
As with any RF device, antenna-related decisions are critical and must be made early. The RF range
of the final product will depend greatly on the choice of antenna and where it is placed. The S4SBR
is available in four versions, selected at the time of order. The on-board antenna versions are built
and tuned to utilize an on-board F-antenna. The external antenna versions include an on-board
50-ohm MCX connector for RF co-ax connection to an external antenna.
External Antenna
An external antenna is connected to the board via an MCX Female coaxial RF connector.
The external antenna used to qualify the board is an omnidirectional 5 dBi whip (shown in the next
figure), made by Manufacturers Marketing Group (MMG). The MMG part number for this antenna
is 16-1000-0. MMG contact information is on page 35. This antenna can be used, or any other
omnidirectional whip antenna with 5 dBi gain or less.
