CJ00 firmware was compiled for the Micro Z CGRS, Z-Surveyor, or Z-Surveyor-FX 
GPS receivers only.  Loading CJ00 firmware into a reciever that does not have 
UFB# (Where # can be from 1 to Z) firwmare already in it, may result in receiver 
damage requiring the receiver to be returned to the factory for non-warranty 
repair.  The opposite path of trying to load any other firmware into the 
above recievers after loading CJ00 firmware may also result in receiver damage
requiring the receiver to be returned to the factory for non-warranty repair.

1.  Primary method for loading CJ00 firmware when directly connected to a PC 
is with the Universal Program Loader, v2.0 or later.
The Universal Program Loader is available on the Ashtech FTP site 
(ftp://ftp.ashtech.com/pub/software).

2. If the receiver is at a remote location, Micro Manager should be used.  
The firmware version currently loaded in the receiver will determine what 
version of Micro Manager should be used.  For firmware versions UFBX through 
UFBZ, MicroManager v1.1.00 should be used.  For firmware versions before UFBX
(UFB1 thru UFBP), an earlier version of Micro Manager should be used.  
The rule is to load new firmware through the MicroManager version of software 
which came with the firwmare version currently loaded in the receiver.
Once upgrading the firmware version to CJ00, you should then upgrade
the version of MicroManager on your PC to version 1.1.00.  Failure to follow 
this method WILL result in no longer being able to communicate with the receiver 
file system or upload new firmware versions.

Ashtech programs are designed to operate with industry standard 
personal computers.  Use of computers which are not 100% compatible 
with these standards may cause abnormal program operation.  For best
results, Asthech recomends that one use the highest quality serial ports 
available.  

A.  To load firmware with Universal Program Loader: 
1. Place firmware in directory on hard drive.
2. Connect and power the receiver to the PC.
3. Start program, using browse window select MZCODE.BIN.
4. Click on OPEN.
5. Select COM port and click on NEXT.
6. Select Type: Z-Surveyor, Mode: Normal, Select Sections: Main Section,
Connection Type: Serial Cable.
7. Connect to the receiver at 115,200 baud. 
8. Click on LOAD.
9. Issue command $PASHS,INI,5,5,5,5,3,0.

B.  To load firmware with MicroManager, 
1. Place firmware in directory on hard drive
2. Connect and power the receiver to the PC.
   Start MicroManager and connect to receiver.  For more information on this refer to 
   the MicroManager manual, section "Connecting to the GPS Receiver".
3. Click on RECEIVER (Top left of MicroManager screen).
4. Click on UPLOAD FIRMWARE (From pull down menu of RECEIVER).
5. Click on BROWSE to select MZCODE.BIN file.  Note that CRC32.DAT file must be in 
   same directory as MZCODE.BIN but you should not select it.
6. Click on START UPLOAD (This loads the firmware file on the external memory card within 
   the receiver).
7. After the firmware has been transferred to the external memory card in the receiver, 
   MicroManager will ask you "Do you wish to ask the receiver to replace its firmware with 
   the uploaded file".  Click YES. 
8. The receiver will check the uploaded file and then acknowledge it will load the new 
   firmware. Click OK.   
9. Depending on whether you are directly connected or remotely connected, MicroManager 
   may ask if you would like to terminate. Regardless, you should terminate MicroManager 
   at this point.
10. Wait 5 minutes and then reconnect to the receiver.  Issue the command
    $PASHS,INI,5,5,5,5,3,0.  
NOTE: In the last step, you should change the serial port baud rate in the INI command
to match the port speed that you are connected to the receiver with. Failure to do this 
will cause the loss of connection between MicroManager and the receiver.  You will then
need to click on POLL RECEIVER BAUD from the drop down menu by clicking on FILE in the 
top left corner if you are directly connected to the receiver or by redialing the modem
if you are remotely connected.
