Chapter 6: Configuring the Serial Server Properties

Server Name

This field displays the name that has been assigned to the Serial Server. You can enter a new Server Name of up to 16 characters. If more than one Serial Server is connected on the LAN, we recommend that you assign a new name to each. When the Serial Server Manager finds a Serial Server on the LAN, it displays the server name and IP Address, enabling the user to distinguish between Serial Servers.

Serial Number

Each Serial Server has a unique serial number. It is fixed and cannot be changed.

Password

Entering a password activates a security feature on the Serial Server. Once a password is entered, it will be required to access the menu and make changes.

DHCP servers are a part of numerous LAN management systems. The DHCP field provides two choices: Disable and Enable. Disable is the normal, or default, setting. When enabled, the Serial Server will send a DHCP request to the DHCP server, which will assign a dynamic IP 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.

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, we recommend using a static IP address.

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 four replies.
