Hardware interface

5.4.1

Configuration and timing signals

M-RST (Pin 55)

This pin provides an active-low reset input to the board.
It causes the board to reset and start searching for
satellites. Reset is an optional input and, if not utilized,
it may be left open.

T-Mark (Pin 41)

This pin provides 1 pulse per second output from the
board, which is synchronized to within 1 microsecond
of GPS time. The output is a CMOS level signal.

This is not available in trickle power mode.

Bootselect (Pin 42) This pin is setting high for programming the flash of

the FALCOM C2D-SI (for instance updating to a new
firmware for the GPS receiver in the FALCOM C2D-
SI).

5.4.2

Serial communication signals

The board supports two full duplex serial channels. All four connections are
at CMOS levels, all support variable baud rates and all can be controlled
from the appropriate screens in SiRFdemo software. You can directly
communicate with a PC serial port.

SDI1 (Pin 50)

This is the main receiving channel and is used to
receive software commands to the board from
SiRFdemo software or from user written software.

SDI2 (Pin 45)

This is the auxiliary receiving channel and is used
to input differential corrections to the board to
enable DGPS navigation.

SDO1 (Pin 49)

This is the main transmitting channel and is used to
output navigation and measurement data to
SiRFdemo or user written software.

SDO2 (Pin 48)

For user’s application.
