Server Properties Configuration

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, 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

Server Properties Configuration

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.

Version & Date

The currently loaded version of the firmware, and when it was released, is shown here.

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.

Server Serial Port

This field indicates the number of the port for with Serial Server properties are currently being displayed. Changing the number in this field will cause all the other fields to display the properties for the specified port. Note, however, that before changing ports, any changes to properties must be Updated (Saved) or the Serial Server will not retain them.

Baud Rate

The serial port baud rate on the Serial Server must match the serial baud rate of the connected device unless using Virtual COM Mode. In Virtual COM Mode the software program will establish serial settings.

Data/Parity/Stop

Set this to match the data format used by the serial device connected when Virtual COM Mode is not being used.
