Bus termination, USS protocol
In order to ensure interference-free USS operation, the bus cable must
be terminated with bus terminating resistors at both ends. The bus
cable from the first USS node to the last USS node is to be regarded as
one
bus cable. The USS bus therefore must be terminated twice. The
bus terminating resistors must be switched in at the
first
bus node (e.g.
master) and
last
bus node (e.g. converter).

S1 bus-terminating switches in the Compact PLUS type of unit
In the Compact and chassis type units, two mutually independent USS
interfaces (SCom1 and SCom2) are available. Switch S1 or S2 is
provided for switching in the terminating resistor.
If the bus-terminating node is a T100 board, the bus terminating
resistors are switched in through the two plug-in jumpers, X8 and X9.
