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.
N N o o t t e e : :
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.
