Handling Error Messages
22: No response from DNS server
What to check on the transmitter
Is the transmitter's DNS address setting set to [Auto assign] or [Manual setting]?
If you are not using a DNS server, set the transmitter's DNS address setting to [Disable]
(p.27).
On the transmitter, does the DNS server's IP address setting match the server's
actual address?
Configure the IP address on the transmitter to match the actual DNS server address
(p.27, 112).
What to check on the DNS server
Is the DNS server on?
Turn the DNS server on.
Are the DNS server settings for IP addresses and the corresponding names
correct?
On the DNS server, make sure IP addresses and the corresponding names are entered
correctly.
Is the DNS server functioning correctly?
Check the DNS server settings to make sure the server is functioning correctly as a DNS
server.
If applicable, ask your network administrator to ensure that the DNS server can be used.
What to check on the network as a whole
Does your network include a router or similar device that serves as a gateway?
If applicable, ask your network administrator for the network gateway address and enter it
on the transmitter (p.27, 112).
Make sure the gateway address setting is correctly entered on all network devices,
including the transmitter.
23: Duplicate IP address
What to check on the transmitter
Is another device on the transmitter network using the same IP address as the
transmitter?
Change the transmitter's IP address to avoid using the same address as another device
on the network. Otherwise, change the IP address of the device that has a redundant
address.
In network environments with a DHCP server, if the transmitter's IP address setting is
[Manual setting], change it to [Auto assign] (p.27).
