Troubleshooting Installation Problems
If you cannot access the connected serial device via the DeviceMaster FreeWire,
first check the network connection and cabling.
• Check the physical cabling to ensure all cables are plugged in (Ethernet and
DB9 serial cable).
• If the appropriate LEDs (LED Indicators
on Page 9) are not illuminated, then
there is probably a bad 10baseT or 100baseTX cable, or the hub port is bad. If
possible, try a different cable and hub port, or try connecting a different device
to the cable.
• Verify that you using the correct values for both IP Address and Port Number.
A common mistake is to assume the TCP port number is the “device number”
on the server.
• If you are using a hub, verify that the hub port is operating correctly by trying
the DeviceMaster FreeWire on a different port.
Troubleshooting Network Configuration Problems
The following information may help you diagnose network configuration problems.
• If you are using TCP/IP, make sure that your PC and the DeviceMaster
FreeWire are on the same IP segment or can reach each other with a PING
command from the host. The IP address you assign to the DeviceMaster
FreeWire must be on the same logical network as your host PCs (e.g., if your
PC has an IP address of 192.189.207.3, the DeviceMaster FreeWire should have
an IP address of 192.189.207.x, where x is an integer between 1 and 254), or you
must properly configure your router address to work with the DeviceMaster
FreeWire.
• If your DeviceMaster FreeWire is set to Auto or DHCP for obtaining an IP
address, it is possible that the DeviceMaster FreeWire IP address can change.
Either configure your DHCP server to give the DeviceMaster FreeWire a
permanent lease, or configure the DeviceMaster FreeWire to be on a STATIC
IP address outside the scope of the DHCP addresses.
