The CRBasic program can read and enter TX325 settings. Settings can also be entered using the
Device Configuration Utility (see
(p. 16) provides the TX325 settings
that can be read and entered.
(p. 17) provides the read-only settings.
The CRBasic program should include the
GOESTable()
and
GOESField()
instructions used
in conjunction with the
DataTable()
instruction to facilitate the transmission of data across
the GOES satellite network. The
GOESTable()
instruction has the following syntax:
GOESTable
(Result, ComPort, Model, BufferControl, Fields_Scan_Order,Newest_
First,Format)
The
Result
is a string variable that holds either the data to be output in its specified format or
a message indicating there are no data to output to the transmitter. For the
Model
, enter 3 to
use the TX325. For the
BufferControl
, a value of 0 writes to the self-timed buffer and a value
of 1 writes to the random buffer.
Data formats and transmission durations
(p. 24) discusses the
Format
options.
The
GOESField()
instruction has the following syntax:
GOESField
(NumVals, Decimation, Precision, Width, SHEF)
The
NumVals
is the number of historical values of the field to output. For
Decimation
, enter
1 to output every value, enter 2 to output every other value, etc.
Width
specifies the number of
characters in the field. Use empty quotes ("") for
SHEF
if no SHEF code is specified.
An example of using the the
GOESTable()
and
GOESField()
instructions follows:
DataTable
(ST_DATA, TRUE, -1)
DataInterval
(0, 15, Min, 4)
GOESTable
(st_table_results, COMRS232, 3, 0, TRUE, TRUE, 3)
GOESField
(4, 1, 3, 6,
""
)
Sample
(1, battery_voltage, IEEE4)
GOESField
(4, 1, 3, 6,
""
)
Sample
(1, panel_temperature, IEEE4)
EndTable
In the main portion of the program, settings are written using
SetSetting()
instruction with
the following the syntax:
SetSetting
(
"FieldName"
, Value )
The
FieldName
must be enclosed in quotes as shown. The following example instruction sets
the port used to communicate with the TX325 to the RS-232 port:
SetSetting
(
“GOESComPort”
, COMRS232)
The CRBasic program reads the TX325 settings using the following format:
Variable
= Settings.FieldName
For example,
goes_comport = Settings.GOESComPort
reads the Com port setting and
stores it in the
GOESComPort
variable. The TX325 settings are typically read in a
TX325 Satellite Transmitter for GOES V2
