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

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 n 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.
