This setup uses multiple network ports on the GEN3i PC section.
Use îž’xed IP address setup with different base IP address and non-overlapping IP-ranges
(Combination of base IP address and net mask) for each of the GEN3i network ports to
make sure the setup always works.
GEN series IP adress setup
Example setup:
GEN3i network 1: 192.168.1.10 mask 255.255.255.0
GEN3i network 2:
192.168.2.10 mask 255.255.255.0
QuantumX module 1:
192.168.1.11 mask 255.255.255.0
QuantumX module 2:
192.168.2.11 mask 255.255.255.0
Background network details
IfthenetworkportsareconguredforDHCPsetup,eachoftheconnectionsusing
theAPIPAprotocoltondafreeIPaddress.Asthetwonetworkportsarenotlinked
together the APIPA protocol on the PTP port does not detect the address used any
of the network devices on the second network port. At random the PTP QuantumX
system might end up with exactly the same network IP address as any of the other
QuantumX systems. If this happens the two systems sharing the same IP address are
not uniquely addressable anymore and the communication fails.
