Troubleshooting
This appendix provides useful information to help you resolve any difficulty you might have with
your camera. Symptoms, possible causes and remedial actions are provided within a quick
reference table.
PINGing your IP Address
By sending a packet to the specified address and waiting for a reply, the PING (Packet Internet
Groper) can determine whether a specific IP address is accessible; it also provides a particularly
useful method for confirming addressing conflicts with your camera on the network.
Having disconnected your camera, follow the instructions below in association with Symptoms,
Possible Causes and Remedial Actions, and run the PING utility to troubleshoot TCP/IP problems
on your network.
1. Start a DOS window
2. Type ping x.x.x.x, where "x.x.x.x" is the IP address of the camera
3. The subsequent replies will provide an explanation as to the cause of the problem. Replies
can be interpreted as defined in the table below:

The camera is
Located on a different
subnet
If the IP address intended for the camera and
the IP address of your PC are located on
different subnets, you will not be able to set
the IP address. Contact your network
administrator for an IP address on the same
subnet as the computer you are performing
the installation from.
Setting the IP
address
The IP address is

device
Disconnect the power from the camera. Run
the Ping command (in a Command/DOS
window, type "ping" and the IP address of the
unit).
If you receive: Relay from<IP address>: bytes
= 32; time=10ms… - this means that the IP
address may already be in use by another
device on your network. You must obtain a
