Trouble Shootings
This chapter is intended to provide solutions to various problems may be caused while using this device. It covers
the problems in the following category.
Installation
It is recommended to check the network connection and cable first if not able to access the connected device via CS-
LAN.
Check if all connections are properly made. (Ethernet or DE-9 connector, serial cable)
Check if ID address and port number are properly entered.
Connect CS-LAN with other port to check if port is properly operated if using a Hub.
Network Settings
Check if the computer and CS-LAN are on the same network if TCP/IP used. (Check the connection with CS-
LAN via a ping command in the computer). IP address of CS-LAN is found on the logical network same as host
computer. For example, If computer’s ID address is 192.189.207.3 and subnet mask is set at 255.255.255.0;
then the IP address of CS-LAN should be set at 192.189.207.x (x should be integral number from 1 to 254).
Also, check if default gateway address is also properly set.
If IP address in CS-LAN is set to be automatically assigned via DHCP, the IP address of CS-LAN can be
changed. Obtain a permanent IP address from DHCP server and set it in CS-LAN or assign a static IP address
in the CS-LAN to fix the address.
Problems may be caused attributed to incorrect or repeated IP address. Check if IP address is correctly
assigned to CS-LAN and if that IP is assigned to other equipment on the network. The IP collision issue in the
CTP/IP connection is very frequent and common. If IP address is not correctly set, it would be highly likely to
be caused by device connection.
Check if both computer and CS0LAN use the same subnet mask. (For example, if CS-LAN uses a subnet
mask of 255.255.255.0, the same subnet mask should be used in the computer as well). Also check if default
gateway is correctly set or not.
If incorrect IP address is assigned, find a DHCP server to check if incorrect address is assigned to CS-LAN.
Window O/S
If the device is not properly connected to window O/S, check the connection via PING x.x.x.x (x.x.x.x is an IP
address of CS-LAN) command at the command prompt. If ping is not properly working, the access to serial
equipment is not possible.
