Data Recording (Z-Surveyor and Z-FX only)
All data recording in the receiver (those that have memory capacity) is done on the
PCMCIA data card also known as a PC card. The PC card is a compact and
convenient way to store a lot of data. The amount of data that can be stored depends
upon the size of the card. PC cards are available in sizes ranging from 2 to 85Mb. The
PC card must be correctly inserted in the PC card slot in the memory compartment to
record data. If the receiver is tracking satellites, and the PC card is correctly inserted,
data will automatically be recorded on the card.
If the PC card is not pre-formatted (Sandisk PC cards are pre-formatted), the PC card
may be formatted like a disk drive or a floppy disk. Use the DOS format before use in
the receiver. Prior to initial use and for all subsequent reformatting, the PC card
should be reformatted by the receiver so that the card is optimally formatted.
Reformatting is done via either the front panel (“DELETE ALL”) or the
$PASHS,CLM command. Refer to “CLM: Clear/Reformat PCMCIA Card” on
page 80 for more information on this command.
The PC card should be reformatted regularly to ensure minimum fragmentation of the card.
While data is recording on the PC card, a LED inside the PC card compartment will
flash red, indicating that the PC card is actively in use. Do not remove the PC card
while the card is actively in use. Loss of data and possible card corruption may result.
If you need to remove the card for any reason while recording data, use the STOP
SESSION function in the SESSIONS menu of the display. This will stop data
recording so the card may be removed and the same or a new card inserted. Data
recording will resume as soon as the card is inserted. If for any reason data recording
does not resume or if the card was not removed, use the START SESSION function
in the SESSIONS menu of the display. The stop session and start session functions
can also be achieved with the serial port commands $PASHS,REC,S and
$PASHS,REC,R, respectively.
PCMCIA File Structure
The PC Card is formatted as a standard DOS drive and can be accessed using any
DOS compatible computer with a PC Card slot (now available on most notebook
computers). As with standard DOS drives, files can be stored in both the root
