Server Properties Configuration
Force Transmit
This field allows the user to set a maximum time limit between transmissions
of data. The value set in this field multiplied by 100 ms determines the Force
Transmit time. When the elapsed time reaches the time configured in this
field, the TCP/IP protocol will pack the data currently in the serial buffer into
a packet and send it out the Ethernet port.
Port Status
This field indicates whether a serial port is connected via the Serial Server to
a virtual COM port of a device on the network.
TCP/UDP Port
This sets the port number for connection. The default port number for the
ESR901 serial port is 4000. The default port numbers for serials ports 1, 2, 3
and 4 are
4000, 4001, 4002 and 4003 respectively.
In all modes of operation, Direct IP or Virtual COM, the port number set in
the
Server Properties menu must match the Virtual COM or socket software
port settings.

Example: The Virtual COM default setting is TCP/UDP Port 4000. If the port #
property is changed to 4001, the virtual COM port will have to be changed to
4001. The hardware settings can be changed from the ESP Manager or
Console Configuration Menu. The Virtual COM port setting also can be
changed within the Device Manager of the computer on which it is installed.
Serial Port Mode
Serial Port Mode allows configuration of the serial server for the following
modes of operation:
•
Console – When this mode is selected and the server is updated, a PC
running a communications program such as HyperTerminal can
communicate with the Serial Server via the Console Mode serial port
(the serial Port on ESR901 or Port 1 on ESR902/904), displaying the
Server Properties screen and allowing configuration of the server and
its ports.
•
Upgrade – When this mode is selected and the server is updated,
firmware can be uploaded into the Serial Server via the
Console Mode
serial port or a virtual COM port mapped to the number of the
Console
Mode
serial port.

Server Properties Configuration
• Default – When this mode is selected and the server is updated, it will
revert the server to its default configuration.
•
RS-232 – When this mode is selected and the server updated, the
selected serial port will become an RS-232 serial port on the server.
•
RS-422 – When this mode is selected and the server updated, the
selected serial port will become an RS-422 serial port on the server.
•
RS-485H – When this mode is selected and the server updated, the
selected serial port will become a two-wire, half-duplex RS-485 serial
port on the server.
•
RS-485F – When this mode is selected and the server updated, the
selected serial port will become a four-wire, full-duplex RS-485 serial
port on the server.
Connection At
When the Connection Mode field is set to Client or Client (no heartbeat),
this field becomes active, allowing the Serial Server (acting as a client) to
connect to the server either on
Power up or on Data Arrival (first character
arriving).
Max Connection
This field allows the user to configure the Serial Server to have up to eight
TCP connections.
Remote IP Address
This is a security feature activated by entering the IP address of the desired
client. The Serial Server will only communicate with the listed IP address
and all other requests for connection will be filtered out. The Serial Server
must be set up as a
TCP or UDP Server to use this feature. The default
setting is
255.255.255.255.
If
Paired Mode is not being used, do not change this setting until the
application has been tested and is communicating properly. Then activate the
address filtering feature.
