This port is used to output the raw GPS measurement data (ie Pseudorange and
Ephemeris data) to WinFrog
Port 3: RS232, Differential Corrections (MX41R, MX 51R, &MX52R) – Input only for
MX9400N/ Input and Output for MX9400R
Port 4: RS422, Equipment/ NMEA – Input/Output
There are also 2 additional connections found in the MX9400’s rear panel:
•
Time: 1PPS - 8.0 to 9.5 VDC; 250 msec pulse; 25 nsec rise time
•
Event Input: Closure
NOTE: These default functions can be modified. WinFrog sends the MX9400 a type 71
message to reconfigure the MX9400’s port functions. Depending on the user made
selections (described below), the Instrumentation / Raw Data Port (Port 2) and NMEA
(Port4) data output may be reassigned to Port 1.
This allows WinFrog to receive multiple data messages from a single MX9400 port
(Port1), into a single computer port.
DEVICE CONFIGURATION INSTRUCTIONS
WINFROG I/O DEVICES > EDIT I/O:
Serial
Configurable Parameters
The MX9400 is added to WinFrog from the
GPS
device group. Configure the
Device I/O
Parameters
dialog box for the appropriate Baud Rate, Data Bits, Stop Bits, Parity, and
Comm Port. These selections refer only to the WinFrog computer port that is connected
to the MX9400 CDU port (i.e. Port 1 on the MX9400, see below for more on the
MX9400’s ports). Select the
OK
button to confirm the port configuration.
The
Configure MX Serial Ports
dialog box now appears, as seen below. This dialog box
allows you to configure the MX9400’s 4 serial ports; defining what data will pass through
which port, the Baud rates for the selected ports, and which items are to be sent
through the selected ports.
Make the required selections (as described below), then click the
OK
button to send this
data to configure the MX9400.
Note that the MX9400’s 4 ports are all combined into a single standard DB25 type
connector found in the back of the MX9400. A special cable is required to “split” the
single port into 4 separate cables that represent the 4 individual ports.
