Receiver Memory Reset
2. It is good practice to reset the Sensor to its factory defaults prior to operating 
it for the first time or when a system malfunction occurs. A reset of the 
internal memory clears the memory and restores the factory defaults. You 
can reset the Sensor internally using the reset plug supplied with the Sensor, 
or externally by issuing a command to the Sensor with an IBM-compatible 
personal computer (PC).
Reset Using Plug—With the Sensor off, insert the reset plug into the port C 
connector. Turn on the Sensor, leave the plug in the connector at least three 
seconds (LED will flash green quickly), then remove plug. Turn the Sensor 
off, then back on. You have now reset the internal memory.
Reset Using INI Command—With the Sensor off, connect a PC to port A 
using the supplied serial data cable. Turn on the Sensor. On the PC, type in 
all uppercase the command $PASHS,INI,5,5,3,0 and press ENTER. This 
command will reset both internal and external memory and power cycle the 
receiver. Refer to Chapter 4, Command Response Formats for more 
information about this command.
Communication with the Sensor
Most standard commercial communications software packages are suitable 
for this purpose, such as TERMINAL in Windows, PROCOMM, etc. The 
program REMOTE.EXE provided by Ashtech is a DOS PC communication 
program similar to PROCOMM. 
3. Two kinds of commands are used to control the Sensor: SET and QUERY. 
The SET commands change the receiver operating parameters, and begin 
with the header $PASHS. The QUERY commands display receiver 
operating parameters, operating status, solutions, and raw data, and begin 
with the header $PASHQ. These commands are presented to the Sensor 
through a cable from an external device such as a PC. 
After setting up the serial interface as described above, you are ready to send 
commands to the Sensor. The letters in your command must be typed in 
ALL UPPER CASE and completed with <Enter> (or 
<CR>(Hex 0D)<LF>(Hex 0A) as applicable for the external device).
