TX320 Transmitter
7.5.1.2 Data Table
The Data Table argument is used to specify which data table the GoesData()
instruction is to copy data from.
7.5.1.3 Table Option
The Table Option is used to specify what data is copied from the data table.
There are three options. Use 0 to specify all new data. Use 1 to specify only
the most current record. Use any other positive number to specify the number
of records to be copied each time GoesData() is executed. When copying data,
the entire record, except the timestamp and record number, is copied from the
datalogger to the TX320 transmitter.
7.5.1.4 Buffer Control
Buffer Control is used to determine which buffer data is copied to, and if the
buffer is erased before data is copied to the buffer. Use 0 to append to the self-
timed buffer; use 1 to overwrite the self-timed buffer. Use 2 to append to the
random buffer, and 3 to overwrite the random buffer.
7.5.1.5 Data Format
Data Format is used to determine what format the data is transmitted in. This
is the format of the data sent over the satellite. The TX320 does not determine
the actual data format used, but can be set to match for data format selected
with this instruction. Use 0 for CSI floating point pseudo binary. Use 1 for
floating point ASCII. Use 2 for 18-bit signed integer pseudo binary. Options 3
through 8 are used for RAWS7 or Fire Weather applications. Option 9 is used
to clear the random buffer.
In dataloggers that support strings as a data type, all data format options except
3 (RAWS7) will support strings. Strings are transmitted from the first
character until the null terminator. If strings contain illegal characters, the
TX320 will replace the character with another character. By default the
replacement character is an asterisk. The replacement character can be
changed.
Both the random and timed buffers of the TX320 can be set to
accept ASCII or pseudo binary data. If the TX320 is set to
pseudo binary, all ASCII data is transmitted as the replacement
character, which is an asterisk by default. When the TX320 is set
to ASCII data, both pseudo binary and ASCII data are
transmitted normally. Data format options 0 and 2 are pseudo
binary, all others are ASCII. NOTE
