Connection At
When the

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

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 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.
