Appendix G. Extended ASCII Command Set
G-10
The random transmission repeat count is the number of times a random
transmission will be repeated. The random transmissions will occur once every
random transmission interval as specified by the randomizing interval. The
valid range of this parameter is 0 – 99. For example, a value of 3 will direct
the transmitter to send the data in the Random buffer 3 times before clearing it.
A value of 0 indicates that random transmissions will occur every random
transmission interval until the random buffer is cleared by the host.
G.3.17 Enable or Disable Random Transmission Message
Counter
Syntax:
RMC=Y/N
Access level: USER
TX312 State: Disabled
If RMC is Y a random message counter will be included at the beginning of the
message, ahead of the user data. If it is N the random message count will not be
included.
G.4 SDI-12 Configuration Commands
G.4.1 Select CS I/O Port Mode
Syntax:
CSMODE=x
Where: x = SDC enables the CS I/O port for SDC slave communications
with a CR10X, CR10X PB or CR1000 data logger. The TX312
address is fixed at 0x41.
x = SDI enables the SDI-12 port as an SDI-12 recorder. Sensors
connected to the SDI-12 port will be polled using the SDI-12
commands entered into the SDI-12 command table.
Access level: USER
TX312 State: Enabled/Disabled
This parameter is saved to non-volatile memory using the SAVE command and
is part of the configuration read back with the RCFG command.
G.4.2 Enter SDI-12 Transparent Mode
Syntax:
ETM
Access level: USER
TX312 State: Enabled/Disabled
Enter SDI-12 transparent mode. The prompt will change from > to * to indicate
that the transmitter is in SDI-12 transparent mode. Any characters entered at
the terminal will be buffered up to the command termination character ‘!’ The
characters will then be sent to the SDI-12 port as SDI-12 commands. No check
for valid command or address is performed other than the requirement for a ‘!’
command terminator. Exit the SDI-12 transparent mode by typing [ESC].
