Troubleshooting

Overview

This chapter covers some common problems that may be encountered while using the XC-DPG503 and some possible solutions to them. If you follow the suggested steps and the XC-DPG503 still does not function properly, contact XiNCOM for further advice.

General Problems

Problem:

I can’t connect to the XC-DPG503 to configure it.

Solution:

Check the following:

 

The XC-DPG503 is properly installed, LAN connections are OK, and

 

the device is powered ON.

 

Ensure that your PC and the XC-DPG503 are on the same network

 

segment.

 

If your PC is set to Obtain an IP Address automatically (DHCP

 

client), restart it.

 

If your PC uses a Fixed (Static) IP address, ensure that it is using an

 

IP Address within the range 192.168.1.2 to 192.168.1.254 and thus

 

compatible with the XC-DPG503’s default IP Address of 192.168.1.1.

 

Also, the Network Mask should be set to 255.255.255.0 to match the

 

XC-DPG503.

 

In Windows, you can check these settings by using Control Panel-

 

Network to check the Properties for the TCP/IP protocol.

Internet Access

Problem 1: When I enter a URL or IP address I get a time out error.

Solution 1: A number of things could be causing this. Try the following troubleshooting steps:

Check if other PCs work. If they do, ensure that your PCs IP settings are correct. If using a Fixed (Static) IP Address, check the Network Mask, Default gateway and DNS as well as the IP Address.

If the PCs are configured correctly, but still not working, check the XC-DPG503. Ensure that it is connected and ON. Connect to it and check its settings. (If you cannot connect to it, check the LAN and power connections.)

If the XC-DPG503 is configured correctly, check your Internet connection (DSL/Cable modem etc) to see that it is working correctly.

Problem 2: Some applications do not run properly when using the XC- DPG503.

Solution 2: The XC-DPG503 processes the data that passes through it and therefore it does not act as a transparent device.

Use the Special Applications feature to allow the use of Internet applications which do not function correctly.

If this does solve the problem you can use the DMZ function. This should work with most applications, but:

• It is a security risk, since the firewall is disabled for the DMZ PC.

• Only one (1) PC can use this feature.
