ESERV-1xT
(Rev. 1210)
LINK STATUS
Link Status
of the currently selected serial server is shown on the Login page of the Ethernet Serial Server
Manager. Link status indicates the type of Ethernet connection between the computer and serial server. It will either
display 10BaseT or 100BaseTX in full duplex or half duplex. Link status is dependant on the LAN, switches, hubs
used in the LAN topology.
MAC ADDRESS
The
MAC Address
is a hardware level address of the serial server that cannot be changed. It is assigned in the
factory. Every Ethernet device manufactured has it own unique MAC address. The MAC address of each serial
server is printed on the device's label. The MAC address of the currently selected serial server is also displayed on
the Login page of the Ethernet Serial Server Manager.
MODEL
The
Model
number of the currently selected serial server is displayed on the Login page of the Ethernet Serial
Server Manager.
NETWORK PROTOCOLS
Network Protocols
available for use on ESERV-1xT serial servers include TCP, UDP, VCOM and Paired Mode .
NETWORK WATCHDOG
Network Watchdog
controls the duration of network inactivity when a network connection is determined idle and
causes the connection to be forced closed. The range is 1 through 65535 milliseconds.
PAIRED MODE
Paired Mode
enables two serial servers to operate across the network like a "wire replacement" between two serial
devices. (Paired Mode
is also called
SERIAL TUNNELING
.) Serial devices connected to serial servers on each
end of the link can communicate as it they were connected by a serial cable.
For Paired Mode to work one serial server must be configured as a TCP server and the other as a TCP client.
The serial server configured as the
TCP client
initiates connections. You must set up the IP address and port
number of the server that you want the client (serial server) to communicate with. You also select whether you want
the serial server to connect at power up or only when it receives data from the device connected to its serial port.
The serial server configured as a
TCP server
waits for connections to be initiated by another network device. You
must set up the TCP port number on which it will listen for connections and set the maximum (up to eight) number
of simultaneous connections it will accept. You can filter the connections it will accept based on specific IP
addresses or ranges of IP addresses that you specify.
PASSWORD
When you first receive the ESERV-1xT serial server from the factory the
Password
is blank so that you can initially
access the serial server without entering a value into this field. To ensure security you should create and save a
password the first time you configure the serial server. After a password has been set up it must be entered each time
you login to the Ethernet Serial Server Manager. The password is used to access the configuration pages from the
the Ethernet Serial Server Manager Login page and can be changed from the General page.
