can only be changed using the serial port command $PASHS,RNG. Table 4.11
describes these modes. The default is 0.
Downloading the Data
The data on the PC card can be either downloaded via the serial port or read from the
PCMCIA drive of the PC. In both cases, the “Download” program needs to be used.
Download handles the protocol required to transfer the data via serial port into the PC
memory. It also converts the packed data into regular format. If the PC card is
inserted in the PCMCIA drive of the PC, only “Convert” needs to run.
DATALOGR
An alternative way to record data is to record data directly onto your PC. This method
is useful if your data card does not have enough space or if you wish to bypass the
download process. To record data directly onto the PC, use the DATALOGR.EXE
program. DATALOGR will collect B and E-files in real time onto your computer.
