General Information
The G12 OEM board Evaluation Kit includes the same antenna and accessories,
but contains a G12 receiver board and an interface board without the aluminum
housing.
An important difference between the G12 OEM board and the G12 Sensor is the
presence of a back-up battery for internal memory. The G12 Sensor has a back-
up battery installed. You must obtain and install a back-up battery for the G12
OEM board.
The power and interface cable supplied with the Sensor Evaluation Kit is used
with other Magellan products. Although it has three serial connectors, only ports A
and B are used with the G12.
G12 firmware is stored in flash memory. New firmware may be loaded into the
receiver through either serial port using a PC. Maintenance releases of firmware
are available on a regular basis to fix known bugs and to implement new features.
When embedding the G12 within another system, Magellan recommends that
external access to one of the receiver’s serial ports be designed into the system
for direct monitoring. For example, many system integrators use an internal data
cable to connect one of the G12 serial ports to an external DB9 connector.
