C - Channel Number
This is the Self Timed channel number assigned by NESDIS. This may also be referred to as
the primary channel.
R - Transmit Rate
This is the transmit rate assigned by NESDIS.
O - Tx Offset Time
This is the transmission time relative to midnight. This is assigned by NESDIS. The offset
time must be less than the transmit rate value.
W - Self Timed Window
NESDIS will assign a window length indicating how much time is allowed to transmit data.
The default is a 15 second window. The options range from a 1 minute to a 5 second window.
B - Self Timed Baud Rate
This option is used to set the baud rate for the Self-Timed transmissions. This may be
different than the random transmission baud rate. This option is dependent on the radio type
and will be 100, 300 or 1200 baud. This will also be assigned by NESDIS.
D - Data Format Options
This opens a new menu dealing with options to define how the data will be formatted. Below
is the Data Format Menu.
--- ST Data Format —--
F - Data Format: SHEF
D - Data Order: SCAN
N - Data Sent First: Newest
H - Send SHEF Headers: No
A - Append 1 Battery Scan:
Yes
S - Scans / Transmission: 8
Enter Option >
F - Data Format
Self-Timed transmissions can be either a SHEF or a binary format. The SHEF format
uses plain ASCII text and is easily readable, but it takes longer to transmit the message.
On the other hand, binary data is transmitted quicker, but the message will need to be
decoded before it can be read. If more data is required, then a binary format may have to
be used. Refer to the GOES Data Format section for more details on the SHEF format
and the GOES binary format. This option cannot be edited while scanning and GOES are
enabled.
