M – SDI-12 Mode
. The SDI-12 mode can be set to master or slave .
The unit defaults to “Slave” mode. In the slave mode the unit emulates a
sensor. In the master mode the unit emulates a datalogger. For CSI datalogger
users, it is recommended that the Vosponder be in the “Slave” mode. See
Appendix A for more information on why and how to use the “Master” mode.

• The Transmit Interval is set in seconds from 0 to 65535 seconds. {default
= 0}
o This value is used to determine the time between transmission of the
last data stored in the unit from the datalogger in the slave mode or the
interval between issuing a sensor query and transmitting the data
retrieved from the sensor(s).
o The interval timer (not the time value) is reset upon DTMF or RCOS
query.
o The keyboard characters entered here are not echoed to the PC
terminal until an <ENTER> key has been pressed.
• The Transmit Delay is set in milliseconds from 0 to 65535. {default =
500}
o This parameter determines the delay time before the Vosponder starts
speaking after it keys the transmitter push-to-talk.
o The keyboard characters entered here are not echoed to the PC
terminal until an <ENTER> key has been pressed.
