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
ESP901
is
4000
. The default port numbers for the
ESP902
are
4000
and
4001
for serial ports 1 and 2 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 ESP901 or Port 1 on ESP902), 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.
•
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-485
– When this mode is selected and the server updated, the
selected serial port will become an 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 ESP901/902 (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.

Server properties must be updated separately for each serial port.
Updating varies slightly depending on which of the four configuration
user interfaces are used.

From the
Server Properties
screen, click the
Update
button to store
the configuration settings for the currently selected port. The vcomui
dialogue box will appear indicating you must restart the device before
the new settings will take effect. Click
