TROUBLESHOOTING
Refer to the following procedures if problems occur during network connection.
1. Confirm that the cable is physically connected. If a switching hub is used, check that
the connection has not been made to the hub’s cascade port. Recent connectors fea-
ture a guard that makes it difficult to insert the connector all the way into the recorder;
check to see that the connector is all the way in.
2. Check the IP addresses and the subnet masks of the PC and the DVR(s). Check that
the network address segments match. Confirm that the PC address segments are
unique. Confirm that settings are not identical to other network terminals or IP ad-
dresses.
3. Confirm that the IP address entered using PING is correct. Do not enter 0 (for ex-
ample, 001). Be sure to enter a space between “ping” and the IP address.
4. Change cables.
5. Restart the PC and the DVR(s). The switching hub address is entered into memory
when the equipment is restarted.
6. Leave the connected units alone for a little while with the power ON. Depending on the
type of switching hub used, there are instances where the IP address of a new device
is not recognized. Leave the units alone for an extended period of time (more than 20
minutes), and then check their condition.
7. Replace the switching hub if one is used.
8. Test the computer’s Ethernet card. Enter 127.0.0.1 in the PING utility and press the
Enter (or Return) key. If a correct response is not returned (that is, the device manager
does not show “!” or “?”), check to see that the Ethernet card driver software is in-
stalled properly. Remove the driver for the Ethernet card once, and then reinstall it.
