IMPORTANT
Additional devices provided with RS-485 are connected in parallel. The
termination of the serial output is carried out only on the last instrument of the
network, by means of a jumper between (B+) and (T). The RS-232 and RS-485
communication ports cannot be connected and used simultaneously.
