Campbell Scientific TX320 Transmitter - Manual (Page 71)

Appendix F. Extended ASCII Command Set
For 100 bps operation on channels 201 – 266, the transmitter will be
configured for international operation. Specifically, the 31-bit international
EOT will be used (0x63CADD04) in place of the ASCII EOT.
Setting the channel number to 0 will disable random transmissions.
F.3.13 Set Random Transmission Bit Rate
Syntax:
RBR=bbbb
Access level: USER
TX320 State: Disabled
This command sets the random transmission bit rate where bbbb is the bit rate
parameter and has valid values of 100, 300 and 1200.
F.3.14 Set Random Transmission Interval
Syntax:
RIN =mm
Access level: USER
TX320 State: Disabled
Set the random transmission randomizing interval to mm minutes. The
randomizing interval is the interval in which a random transmission will occur
if there is data in the random transmission buffer. The actual transmission time
will be random, but on average will occur at this rate. Valid range is 5 to 99
minutes.
F.3.15 Set Random Transmission Randomizing Percentage
Syntax:
RPC =mm
Access level: USER
TX320 State: Disabled
This value determines the range of randomization as a percentage of the
randomizing interval. Random transmissions will occur at a uniformly
distributed random time within this range and on average occur at the
randomizing interval rate. Valid range is 10 to 50%.
For example, for a randomizing interval = 15 (minutes) and a randomizing
percentage = 20 (%), then the time between any two random transmissions will
be 12 to 18 minutes (15 ± 3 minutes).
F.3.16 Set Random Transmission Repeat Count
Syntax:
RRC =xx
Access level: USER
TX320 State: Disabled
