values will remain. When DHCP is enabled, the IP Address, Netmask and Gateway fields become inaccessible and cannot be changed by the user.

Note:

A dynamic address assigned by the DHCP server may change if the server loses the Ethernet connection or power is removed. The host (client) communication software requests a connection to the specific IP address of the serial server. If the DHCP reassigns a different IP address the software will not be able to communicate with the hardware. Therefore, using a static IP address is recommended.

IP Address

Software or hardware attempting to access the Serial Server via the network must know the IP Address of the server. A static IP address is retained and remains the same each time the server is powered up or starts/restarts. The default IP address of the Serial Server is printed on a label on its bottom cover. Entering an appropriate address in the IP Address field and updating the server will change the server’s IP address. The network administrator can assign/establish the static address or group of addresses to be used.

The IP Address of the Serial Server can be confirmed using the DOS Ping command.

Note:

To use Ping to check for communications:

-Access a DOS window (in XP click Start, then Run)

-At run prompt enter: CMD

-In the DOS window enter: Ping xxx.xxx.xxx.xxx (IP address for the server to be confirmed)

-The command will return the Ping results indicating 4 replies
