Default Multiplexer Configuration - Digital Equipment MUXserver 100 Reference Manual

In any network involving the MUXserver 100 and one or two
DECmux II units, the MUXserver 100 must be the MASTER (this is
the default setting), and the two DECmux II units must be SLAVES
(this is also the default setting). If either DECmux II unit is set to
MASTER mode, communications between the MUXserver 100 and
that DECmux will fail.
