Interfaces for connection to the
system bus (XDAC1, XDAC2)
The NK350 network coupler integrated in
the CS351x-D NK Compact System allows
connecting the compact system to the sys-
tem bus of the 350 system. In this case, ,the
CS351x-D NK Compact System can only
cooperate with a KE350 communication
unit that is installed in the BT356 subrack or
SB356 system box. You cannot operate the
CS351x-D NK as isolated system.
The NK350 network coupler allows up to
40 tightening channels in up to 16 BT356
subracks, SB35x system boxes and Com-
pact System CS351x-D NK to be net-
worked. It is equipped with an LED display
for the illustration of network conditions.
The address of the
CS351x-D NK is set using the hex coding
switch..
Additional bus termination resistors are not
required.
The total cable length in the network is limi-
ted to 150 m. The maximum cable length
between two network couplers may not ex-
ceed 50 m. The network cable between two
network couplers may consist of no more
than four partial segments. A ring structure
is not permissible in the network configura-
tion.
The D-Sub plugs of the network
cables NKLxx have the protection
class IP40. If several cables are
assembled, the user must ensure
the higher degree of protection
that is possibly required.
If a network cable is created from several
partial segments, distance segments are re-
quired at the connection points.
