Serial Timeout
Default is 0, or no timeout. Setting timeout to any value between 1 and 65535 seconds activates
it. If communications are idle for specified timeout value the serial server will reset and make
itself available for another connection.
TCP Alive Timeout
This 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 HEX1 and Delimiter HEX 2
These two 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 TRP-C32S 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.
