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-C38 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.
Force Transmit
This field allows the user to set a maximum time limit between transmissions of data. The value
set in this field multiplied by 100 ms determines the Force Transmit time. When the elapsed time
reaches the time configured in this field, the TCP/IP protocol will pack the data currently in the
serial buffer into a packet and send it out the Ethernet port.
Port Status
This field indicates whether a serial port is connected to a server or by a client.
TCP/UDP Port
The TCP/UDP Port defines a communication port number. In all modes of operating, Virtual
COM, Direct IP, and Paired modes, both the TCP/UDP Client and server port settings must
match.
For example the Virtual COM defaults setting TCP/UDP Port # 4000. If the port # of the TRP-C38
is changed to 4001, the Virtual COM TCP/UDP Port will have to be changed to 4001.
Serial Port Mode
This allows configuration of the serial server for the following modes of operation:
• Console – When this mode is selected and the server is updated, a PC running a
communication program such as Hyper-terminal can communicate with the
