Connection Cable Pinout:
Does the Host ATS PDU record the Status Records of the Guest ATS PDUs
and itself?
Yes, the Host ATS PDU records the Status Records for all the ATS PDUs in the
daisy-chain.
Will the Status Records of the Guest ATS PDUs logged in the Host ATS PDU
be cleared if the Guest ATS PDUs are disconnected from the Host ATS PDU?
Yes, once the Guest ATS PDUs are removed, the Status Records logged in the
Host ATS PDU will be cleared. As long as the Host ATS PDU does not connect
to other ATS PDUs, the Status Records of the disconnected ATS PDU can be
displayed when it is re-connected to the Host ATS PDU. If the Host ATS PDU
connects to different ATS PDUs, the Status Records of the removed ATS PDU
will be entirely cleared.
Are the Guest ATS PDUs able to connect to the network when they are
daisy-chained?
Yes, even when the ATS PDUs are daisy-chained, the Guest ATS PDUs are
able to connect to the network directly. Note that a Guest ATS PDU will
require having its own Ethernet cable connected to the network.
What will happen if a 5th ATS PDU is added to a daisy-chain?
The maximum number of ATS PDUs that can be connected in one daisy-
chain is 4. The daisy-chain functionality will not work until the fifth ATS PDU
is removed.
What is the maximum recommended length of the Ethernet cable to
daisy-chain the ATS PDUs?
50 ft (15 m)
