Ashtech Micro-Z Interface Protocol Quick Reference

System Default Settings

Serial port baud rate: 9600, 8, N, 1
Clock steering: Enabled
Raw data output rate: 20.0 sec

Once new values are set they can be saved to memory by issuing a $PASHS,SAV,Y command to the serial port. Parameters are saved to memory until a memory reset or a receiver initialization is performed. This will reset all parameters back to their defaults.

The following command will force the receiver to default values: $PASHS,RST (hit Enter)

To clear the stored almanac, emphemeris data, reset the receiver memory, set the serial port baud rate to the specified rates, and/or send the modem initialization string through the specified port send the $PASHS,INI command. The format of the command is $PASHS,INI,d1,d2,d3,d4,d5,c6 where d1-d4 are the default baud rate codes for ports A-D, d5 is the reset memory code and takes a value of 0-3 with the following codes:

0 = No memory reset
1 = Reset internal memory/battery back-up memory
2 = Reset/reformat memory card
3 = Reset internal memory and memory card

For example, sending $PASHS,INI,5,5,5,5,3,0 will do a full receiver reset. Codes 0 and 2 behave like a power cycle. Codes 1 and 3 reset all parameters to default as well as the ephemeris and almanac. Code 2 and 3 reformat the memory card by clearing the FAT table and directory structure. The parameter c6 sets the modem initialization and takes values A-D or 0 = no initialization.

System Initialization - Baud Rate

The $PASHQ,PRT quarries the baud rate of the current port. The return is $PASHR,PRT,c1,d2*cc where c1 is the port (A,B,C,D), d2 is the port code listed below and *cc is the checksum.

0 = 300
1 = 600
2 = 1200
3 = 2400
4 = 4800
5 = 9600
6 = 19200
7 = 38400
8 = 56800
9 = 115200

To set the baud rate of a port send the following command $PASHS,SPD,A,9 (hit Enter) this sets port A to 115200.
