ISM Permanent Mode :
Additionally you can change the data transmission rate of the ISM radio modules from 9600 baud
230400 baud ( see table on page 11
RF data rate ). With this data transmission rate the ISM Permanent
Mode can be used which allows you to transmit measuring values automatically every time the
value changes.
Advantages of the 230400 Baud data rate :
a ) approximately 1 million instead of only 200.000
transmissions possible, before the
batteries run out
b ) ISM Permanent Mode can be used
Disadvantages of the 230400 Baud data rate :
a ) not IBRit-rf1 compatible
b ) only approximately 60% range in comparison
with 9600 Baud
Please note that the change of the data transmission rate is only possible if the address of the radio
module has been set to
500
before ( see page 11 ). After the change of data rate the address can be
switched back to the old value again.
After changing the data transmission rate of the ISM radio modules, it has to be also changed for the
ISM - usb, so that the ISM-usb will be able to receive the values from the radio modules and change
their settings.
To do this, please click in the hardware setup on one of the
Setup
buttons on the right side :
