6.18 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).
6.19 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 MLB-S4101 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.
6.20 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.
6.21 Port Status
This field indicates whether a serial port is connected to a server or by a client.
6.22 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 default setting TCP/UDP Port # 4000. If the port # of the MLB-S4101 is changed to 4001,
the Virtual COM TCP/UDP Port will have to be changed to 4001.
6.23 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 Hyperterminal can communicate with the serial server via the Console Mode serial port (Port 1 on MLB-S4101),
displaying the Server Properties screen and allowing configuration of the server and its ports.

Upgrade
– When this mode is selected and the server is updated, firmware can be uploaded into the serial server
via the Console Mode serial port or a virtual COM port mapped to the number of the Console Mode serial port.

Default
– When this mode is selected and the server is updated, it will revert the server to its default configuration.

RS-232
– When this mode is selected and the server is updated, the selected serial port will become a RS-232
serial port on the server.

RS-422
– When this mode is selected and the server is updated, the selected serial port will become a RS-422
serial port on the server.

RS-485
– When this mode is selected and the server is updated, the selected serial port will become a RS-485
serial port on the server.
