12.2.3 Troubleshooting – Please refer to the following if problems occur
during network connection procedures.
Please check each of the following items (a – h).
a) Confirm that the cable is physically connected.
Check to see that the connection has not been made to the hub's cascade port. Recent
connectors feature a guard that makes it
difficult to insert them all the way into the recorder; check to see that the connector
is all the way in.
b) Check the IP addresses and the subnet masks of the PC and the recorder(s).
Check that the network address segments correctly match up. Confirm that the host
address segments are unique. Confirm that settings are not
identical to other network terminals or IP addresses.
c) Confirm that the IP address entered using PING is correct.
Do not enter zero (e.g., 001). Be sure to enter a space between "ping" and the IP
address.
d) Change cables.
e) Restart the PC and the recorder(s).
The switching hub address gets entered into memory as a result
of the restarting process.
f) Leave the connected units alone for a little while with their 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 (over 20 minutes), and check their condition after this.
g) Replace the switching hub.
h) Test the computer's Ethernet card.
Enter 127.0.0.1 in the PING utility and press the Return key. If a
correct response is not returned (i.e., the device manager does not show "!" or "?"),
check to see that the Ethernet card driver software is installed properly.
Please remove the driver for the Ethernet card once, and then reinstall it.
