specified port. Before changing ports, any change to properties must be Updated (Saved) or SCB-A08
will not retain them. Suggest use default setting.
- Baud rate: The serial port baud rate on SCB-A08 must match the serial baud rate of the connected
device. (Suggest use default setting)
- Data/Parity/Stop: This setting will have to match the data format of the connected device. (Suggest use
default setting)
- Flow control: The flow control setting must match the connected serial device. (Suggest use default
setting)
- Protocol: Select TCP or UDP protocol. If the application does not require a UDP connection, select TCP.
TCP guarantees reliable communication with error checking whereas UDP provides faster transmission.
When UDP mode is chosen the Serial timeout, TCP alive timeout, Connection mode, Connection at,
Maximum connection and Remote IP address fields are replaced with the following three fields:
Destination IP address range, Port number and Source IP address range. In this mode the server can be
configured to broadcast data to and receive data from multiple IP addresses. Four IP address range
fields are provided. (Suggest use default setting)
- 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. (Suggest use default setting)
- 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. (Suggest use default setting)
- 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). (Suggest use default setting)
 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).
- UID: UID (Unit Identifier) is MODBUS slave address (0x0~0xff), It’s be defined in MODBUS TCP frame format,
In Properties, We provide consumer define UID. (Suggest use default setting)
- Delimiter HEX1 and delimiter HEX2: 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 SCB-A08 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. (Suggest use default setting)
- 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. (Suggest use default setting)
- 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 I/O
box configuration port is 4001.
- Serial port mode: This allows configuration of the serial server for the following modes of operation:
