19.12 OUTPUTTING DATA
OUTPUT TO A COMPUTER
The GDP-32
II
stores 2 to 10 days' worth of data in memory. Zonge Engineering recommends
that you dump data to an external computer at the end of every day in the field. Data are dumped
to a computer using a serial dump cable for the data transfer procedure listed below. Before
outputting data, be sure to check the Serial Port configuration (see Section 19.11 above)
1. Attach the Serial I/O Cable between the serial port of the GDP-32
II
and the serial port
connector on your computer. This cable has a military plug at one end and a standard
RS-232 9- or 25-pin D-connector at the other end.
2. Start the file transfer program on the computer (such as HyperTerminal).
3. Open a data file on the computer (e.g. for HyperTerminal: Transfer / Capture Text). The
data will be sent from the GDP-32
II
into this file.
4. Verify that the program is connected with the receiver.
5. On the GDP-32
II
, press to enter Data Mode. Press
Escape
,
Escape
to access the
Data Mode Main Menu.
6. Press , Access Cache.
7. Select the cache you wish to dump (e.g. press for Field Data, etc.) In the Field
Data cache some or all of the data can be output. For board or antenna calibration data
the entire contents of the cache are dumped.
8. Immediately upon selecting the output mode, the receiver begins transferring data. The
receiver LCD displays:
Transmitting
x blocks found to transmit
Check this last message to make sure all the blocks selected are transmitting.
9. When the output is initiated, the data scrolls onto the computer display.
10. If the GDP-32
II
outputs data faster than the computer can accept it, the screen displays:
Waiting
as the data transfer stalls until the computer catches up.
11. When transfer is complete, the data stops scrolling on the computer terminal. The GDP-
32
II
LCD displays the Cache Menu.
12. Close the data file on the computer (e.g. for HyperTerminal: Transfer / Capture Text /
Stop).
13. Exit the computer file transfer program.
14. Check the new file for garbled or missing data before assuming that this process is
complete. Verification consists of noting the number of data blocks in the GDP-32
II
