*) Not available if the instrument is battery powered.
Use only if the instrument is connected to the provided 24 VDC power supply.
Maximum load: 5 W.
If the RS485 network exceeds 100 metres in length or baud-rate is higher than 9600, two
terminating resistors are needed at the ends of the network. Two 120 ohm resistors are
to be connected, between the “+” and “–“ terminals of the line on terminal strip of the
instrument furthest away in the network. If should be there different instruments or
converters, refer to the specific manuals to determine whether it is necessary to connect
the above-mentioned resistors.
