Baud Rate
The serial port baud rate on the ESP904 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.
Data/Parity/Stop
Set this to match the data format used by the device connected when the
Virtual COM mode is not being used.
Flow Control
The Flow Control setting must match the requirements of the device
connected.

TCP/UDP Protocol
Select TCP (Transmission Control Protocol) or UDP (User Datagram
Protocol) protocol. If the application does not require a UDP connection,
select TCP. TCP guarantees reliable communication with error checking
whereas UDP provides faster transmission.
TCP/UDP Port
This sets the port number for connection. The default port number is
4000
,
4001
,
4002
, and
4003
for serial ports 1, 2, 3, and 4 respectively.
In all modes of operation,
Direct IP
or
Virtual COM
, the port number set in
the ESP904 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.
Remote IP Address
This is a security feature activated by entering the IP address of the desired
client. The ESP904 will only communicate with the listed IP address and all
other requests for connection will be filtered out. The ESP904 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.

Timeout
Default for the Timeout property is 0, or no timeout. Setting Timeout to any
value between 1 and 255 seconds activates it. If set to 5 seconds and the
ESP904 is configured as a Server. In this scenario the Client makes a
connection and communications start. If communications are ideal for 5
seconds the ESP904 will reset and make itself available for another client
connection.
