transmitter
1. Connect the ground potentials of the signal transmitter and the router
node.
2. Connect the positive terminal of the power connection next to the IO
connector to the open-drain output of the signal transmitter via the
pull-up resistor X.
3. In addition, connect the open drain output of the signal transmitter to
one of the digital inputs DI1, DI2 or DI3.
The pull-up resistor depends on the open-drain output of the signal
transmitter. A possible value is 1 k
Ω
.
IMPORTANT
Calculation of pull-up resistance
Pull-up resistors that are too small can damage the power connection next
to the IO-Connector and overload the open-drain connection of the Signal
Giver. Too large pull-up resistors make the signal unclean.
The pull-up resistor must be as small as possible and as large as neces-
sary.
1. Do not select a value lower than 16.5
Ω
.
2. Do not select unnecessarily large values.
