If the RS485 network exceeds 100 metres in length or baud-rate over 9600 are used,
close the two jumpers, called "RS-485 termination", to activate two 120 ohm
terminating resistors between the ‘+’ and ‘–’ terminals of the line, on the terminal strip
of the furthest instruments.

Should there be different instruments or converters, refer

to the specific manuals to determine whether it is necessary to connect the above-
mentioned resistors.
