How to Download Commands from the PC
Use your favorite ASCII text editor (DOS Edit or Windows Notepad are easy and readily available) to
create a file as shown below:
G859CMD,00,$PASHS,NME,SAT,A,ON
G859CMD,01,$PASHS,SPD,B,2
G859CMD,02,$PASHS,RTC,REM,B
G859CMD,03,$PASHS,RTC,BAS,A
G859CMD,04,$PASHS,RTC,TYP,9,1
G859CMD,05,$PASHS,NME,GGA,A,ON
G859TXT,06,Fell into a hole
G859TXT,07,Dropped the magnetometer
G859END
The first six lines set up RS-232 commands. The keyword G-858BPCMD determines this. The
second field, the two digit number, specifies which key the command or note is associated with. The
numbers 00 through 09 correspond to the number keys on the console. The other keys are as shown below:
10 MARK 1
5
CHART
11 LINE 1
6
MAP
12 PAUSE 1
7
ENTER
13 ESC 1
8
POWER
14 MENU
Note: The ASCII commands or field notes will only be active during the one
of the active modes of operation. These are the Ready state, Acquire state, and
Pause state, as explained on page 53.
Each key also retains its normal function. For example, if the MARK key is assigned to an RS-232
command, pressing it will still perform the normal MARK key function. This is useful, for example, if you
wanted to store a GPS reading only at each MARK location. Then, you would program the MARK key
with the command to query the GPS for the current position. In doing this, you would probably also want
to program the END LINE key with the same command. Then, you will get a GPS confirmation at each
fiducial point.
