Server Properties Configuration

Chapter 5: CONFIGURING THE ESP904

SERVER PROPERTIES

The VLINX Serial Server can be configured using any of four different user interfaces: the ESP Manager software, the Web Server, Console Mode or Telnet. The Server Properties described in this chapter can be changed from any of these user interfaces.

Description of the Server Properties

Server Name

A new Server Name of up to 16 characters can be entered. If more than one ESP901 or ESP902 or ESP904 Servers are connected on the LAN it is recommended that a new name be assigned to each. When the ESP Manager finds ESP Servers on the LAN it displays the server name and IP Address allowing the user to distinguish between ESP servers.

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

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 ESP904 will send a DHCP request to the DHCP server, which will assign a dynamic IP address, net mask, and gateway to the ESP904. If a DHCP server is not available on the network the ESP904 will time out after 10 seconds and the default values will remain.

Note:

A dynamic address assigned by the DHCP server may change if the ESP904 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.

Server Properties Configuration

IP Address

Software or hardware attempting to access the ESP904 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 ESP904 server is printed on a label on the bottom cover of the ESP904. 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 ESP904 server can be confirmed using the DOS Ping command.

Note:

To use Ping to check for communications:

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

-At run prompt enter: CMD

-In the DOS window enter: Ping xxx.xxx.xxx.xxx (IP address for the ESP904 to be confirmed)

-The command will return the Ping results indicating 4 replies

Netmask

The default LAN netmask is configured for a Class C address. The user may change this. Default is 255.255.255.0

Gateway

The Gateway IP address allows users to access the serial server from outside the LAN.

MAC Address

The MAC address is fixed and cannot be changed. It is assigned in the factory. Every Ethernet device manufactured has it own unique MAC address.

Link Status

Link status automatically displays the type of Ethernet connection. It will either display 10BaseT or 100BaseTX in full duplex or half duplex. This will depend on the LAN, switches, hubs used in the LAN topology.
