address, net mask, and gateway to the Serial Server. If a DHCP server
is not available on the network the Serial Server will time out after 10
seconds and the default values will remain. When DHCP is enabled, the
IP Address, Netmask and Gateway fields become inaccessible and
cannot be changed by the user.

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.

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
