Chapter 6: Configuring the Serial Server Properties
Figure 6-3. Pinging using the DOS command window.
Netmask
The default LAN netmask is configured for a Class C address. The user may change this. The 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 and 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
Server Serial Port
This field indicates the number of the port for which 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: Before changing ports, any changes to properties must be Updated (Saved) or the unit 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.
Flow Control
The Flow Control setting must match the requirements of the serial device connected.
NOTE: Select “None” when setting the port as RS-485 or 4-wire RS-422.
TCP/UDP Protocol
Select TCP (Transmission Control Protocol) or UDP (User Datagram Protocol) protocol. If the application does not require a UDP connection, select TCP. TCP guarantees reliable communication with error checking, whereas UDP provides faster transmission.
