TGT1 GOES Transmitter
13
TABLE 8.3-1 *#60 Commands
Command
Number Description
1 Displays the current TGT-1 time; hours, minutes, and seconds
are the parameters. The TGT-1 time is retrieved when the “A”
key is pressed.
2 The amount of time until the next transmission of the active
buffer; parameters are days, hours, minutes, and seconds. If
[31:31:63:63] is displayed, the active buffer contains no data.
The time is retrieved when the “A” key is pressed. The active
buffer is set using command 6 and 7.
3 Forward power is the first parameter and reflected power is the
second (see Section 7).
4 The first parameter displays the number of errors. Parameters
2-9 list the history of errors, where parameter 2 is the most
recent. Call CSI to decode errors.
5 Number of bytes in self-timed or random buffer ( used after
command 6 or 7 ).
6 Selects self-timed buffer ( used before command 5 ).
7 Selects random buffer ( used before command 5 ).
8 Initiates test transmission of data in the random buffer. You
must be assigned a random channel (see *# parameter 13) or
obtain from NESDIS a channel for testing. The random buffer
must contain data. The TGT-1 will not perform a test
transmission more often then once each minute. Clear the
random buffer before final TGT-1 setup. Appendix F contains
a datalogger program that dumps data into the random buffer.
9. Programming the Datalogger
9.1 CR10X and CR10
9.1.1 Instruction 120 and Instruction 124 (Fire Weather)
CR10X program Instruction 120 transfers the final storage data to the
transmitter's buffer and designates locations for the forward/reflected power.
The CR10s use Instruction 99 instead of Instruction 120. The CR10
Instruction 99 and CR10X Instruction 120 are identical except for the
instruction number. This instruction also automatically compares the
datalogger to the transmitter clock. If the clocks differ more than 3 seconds,
the datalogger's clock is set to the transmitter's. However, only the seconds are
compared. Therefore, the datalogger's clock is
NOT reset when the minutes or
hours differ. The complete time (HH:MM:SS) will be updated if the clocks
differ by more than 3 seconds. Table 9.1-1 lists and describes Instruction 120's
parameters.
