You want to check whether the correct baud rate has been set.
1.
Switch off the coupler's 24 V supply
2.
Remove all the terminals except the KL9010 end terminal
3.
Set the x10 address selection switch to 0 and the x1 switch to 3
4.
Switch on the coupler's 24 V supply again
The coupler indicates the set baud rate via the LEDs.
3 x flashes of the I/O RUN and I/O ERR LEDs means 9600 baud

Example
I/O Run, I/O ERR
Now you want to set a new rate of 1200 baud
5.
Switch off the coupler's 24 V supply
6.
Set the x10 address selection switch to 3 and the x1 switch to 6
7.
Switch on the coupler's 24 V supply again
The coupler indicates the new set baud rate via the LEDs.
6 x flashes of the I/O RUN and I/O ERR LEDs means 1200 baud
Incorrect Entry
If a parameter is set that the Modbus coupler does not recognize, this is
indicated by a constant even flashing of the I/O RUN and I/O ERR LEDs,
while all the other LEDs remain off.
KS2000
The parameterization settings can also be carried out with the KS2000
software.
