The bus termination can be carried out in various ways.
It can either be carried out via external resistors and a separate
power supply, independent of the module, according to figure
10.5. In this case we recommend to use the indicated resistors
for the bus termination.
Or the bus termination is connected with the bus users at the be-
ginning and at the end of a bus line. Most of the RS485 connec-
tions for controls, computers, repeaters, interface converters, etc.
offer this option.
Also with datalogger

this option is given. Via
the bus termination plug which is available as accessory and in-
stalled at the right port on the frontside of the device, the bus ter-
mination at this module can be additionally connected. Two jump-
ers which connect the bus with the bus termination in the data-
logger are integrated in the bus termination plug.
Note:
Instead of the bus termination module separate jumpers
can also be used for the bus termination. In this case, please
make absolutely sure that the jumper clips are installed as indi-
cated, and that the bus leads or the bus termination are not short-
circuited by mistake!
