Serial Timeout
Default for the Timeout property is 0, or no timeout. Setting Timeout to any
value between 1 and 65535 seconds activates it. If
Timeout is set to 5
seconds and the Serial Server is configured as a
Server, the Client makes a
connection and communications starts. If communications are ideal for 5
seconds the
Serial Server will reset and make itself available for another
client connection.
TCP Alive Timeout
The Serial Server monitors TCP activity. If TCP activity stops for the length
of time specified in this field the connection will be closed. This field can be
set to any value between 0 and 255 minutes. If zero, or no value, is entered
into this field the server will not disconnect.
Connection Mode
The Connection Mode field has three options: Server, Client and Client (no
heartbeat). When Client or Client (no heartbeat) is selected the
Connection at
field automatically becomes active (allowing the user to
select Power up or Data Arrival).
• When using the
Virtual COM Port feature, select Server.
• When using a
TCP or UDP Socket program, select Server.
• When using
Paired Mode communication between two serial servers set
up one as a
Client and the other as a Server.
• When connecting to a server that does not support
Heartbeat, select
Client (no Heartbeat).
Delimiter HEX 1 and Delimiter HEX 2
These fields allow the user to enter two ASCII characters (in hex format) that
delimit the beginning and end of a message. When a message with both these
delimiters is received at the serial port, the data contained in the serial buffer
is placed in an Ethernet packet and sent out the Ethernet port. If only
Delimiter 1 is set (Delimiter 2 is zero or blank), upon receiving Delimiter 1
the Serial Server will put all the data in the serial buffer in an Ethernet packet
and send it out the Ethernet port. If serial data greater than 1 kilobyte is
received it will automatically be placed in an Ethernet packet and sent out the
Ethernet port.
