QuantumX in an (Ethernet) network and DeviceScan with catman®Easy/AP
Question/Problem
I have connected a QuantumX or SomatXR series amplifier via a network
cable and started the catman®AP software, but I cannot get a connection to
the amplifier.
The software advises:
"The device scan cannot find any connected devices. …”
Reply/Solution
S If the module is found, but connection is not possible, check the TCP/IP
settings of the module and the network adapter on the PC. We recommend
DHCP / APIPA. With a manual setting, the same subnet mask should be
set. Fixed IP addresses should be identical at least in their first two digits.
S Check that the Ethernet cable is plugged in
S The Windows® firewall can block the connection during device scanning
and should be switched off temporarily for the duration of the measurement.
The settings for the firewall can be found under Control panel *> Secur
ity center *> “Windows Firewall”.
S Wireless network adapters (WLAN). These can, depending on the configur
ation, take priority in operating the network and thereby disturb the wired
network scan. If a WLAN adapter is present on the notebook or laptop, it
must be deactivated.
S The firewall of an installed VPNClient. This can also disturb a network scan.
For example, the setting "Stateful Firewall (Always On)" is activated by de
fault in the CISCO VPN Client. This should be temporarily deactivated for
the QuantumX device scan.
S A virus scanner can also possibly block the network scan due to its proper
ties. It should therefore be temporarily deactivated.
