• 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.
