Troubleshooting

Installation Problems

If you cannot make connections to the devices in the same network using sLAN/all, check your network connection

and cables.

 Check if everything is properly connected (Ethernet, DE-9 connector)

 Check if the IP address and port number is properly configured.

 If you are using a network hub, switch currently using Ethernet port to different one to make sure the problem

does not exist in the port itself. Also, change the Ethernet cable to different one.

Windows Operating System Problems

 If the device cannot be found from the configuration utility or cannot connect to the configuration web page,

type “PING N.N.N.N” (Where N is a value from 0 to 255) without quotes from the command line prompt to

check the connection status. (For example, “PING 192.168.0.223” without quotes.) If it does not return any

value or responses, it means that the sLAN/all device is not properly connected.

1. Check the network cable

2. Allow network connection from the Windows Firewall

3. Disable the Windows Firewall

Network Configuration Problems

 When using TCP/IP network, check if your computer and sLAN/all are connected to the same network. Use

ping command to check the connection between the computer and the sLAN/all. The IP address of a sLAN/all

must be configured with the same network as your computer. For example, if your computer has IP address of

192.189.207.3, and the subnet mask is 255.255.255.0, the IP address of the sLAN/all must be 192.189.207.N

(Where N is from 1 to 254. Also, check if the gateway address is set correctly.

 If the sLAN/all is set to receive the IP address automatically from the DHCP server, the IP address of the

sLAN/all may change. In this case, set the IP address of the sLAN/all to be fixed from the DHCP server, or

change the settings from the sLAN/all to have a fixed IP address.

 Unmatched or duplicate IP address can cause errors. Check if the IP address of the sLAN/all is assigned

properly. Also, check if there are any other devices with the same IP address. The duplicate IP address issue is

very common while using TCP/IP network. Regarding unmatched IP address, many users connect the sLAN/all

device to the network without changing the IP address to be used in the field. Make sure to change the IP

address and other configurations before applying at the field.
