Campbell Scientific TX320 Transmitter - Manual (Page 74)

Appendix F. Extended ASCII Command Set
Loading data into the random transmission buffer, triggers the random
reporting sequence. Once triggered, the random reporting mechanism will
send the data loaded in the buffer for the number of transmissions as specified
by the random repeat count. The buffer will be cleared automatically when the
number of transmissions specified have occurred.
If the command is received within 1 minute or during a random transmission,
the data will not be included in the current transmission but will be buffered for
the next one.
If there is more data loaded into the buffer than can be transmitted at the
assigned bit rate the message will be truncated.
