IP Address
A static IP address can also be assigned in this section of the menu. A dynamic
address assigned by the DHCP server may change if the ESP901 looses 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. It
is recommended to use a static IP address.
A static IP address is permanent and will not change unless changed in the menu. In
most cases the network administrator establishes the static address to be used.
Net Mask
The default LAN net mask is configured for a Class C address. This maybe
reconfigured by the user.
Gateway
The gateway IP address allows users to access the serial server from outside the LAN.
MAC Address
The MAC address is not adjustable. This 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 10 BaseT or 100BaseTX in full duplex or half duplex. This will depend on the
LAN, switches, hubs used in the LAN topology.
Baud Rate
The serial port baud rate on the ESP901 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. Use the arrow keys to change the
setting to the desired baud rate.
Data/Parity/Stop
This setting will have to match the data format of the connected device. Tab to the
Data/Parity/Stop field and arrow to the desired selection.
