MLiS-S4101 Manual
1 Introduction
The MLB-S4101 Ethernet serial server connects RS-232, 422, 485 serial devices to an Ethernet LAN/WAN providing a
reliable communication connection. Existing Windows based serial software using standard Windows API does not have
to be modified to communicate over an Ethernet LAN to a serial device. The MLB-S4101 virtual COM port will make this
an easy transition.
The MLB-S4101
operates in “Direct IP Mode”, “Virtual COM Mode”, and “Paired Mode”. The MLB-S4101 has one
asynchronous DB-9 serial port, and have one 10/100 Mbps Ethernet RJ-45 connection. The Ethernet port wills auto-select
10BaseT or 100BaseTX.
The MLB-S4101 Windows driver installs virtual COM ports in the Device Manager of the operating system. The virtual
COM port is designed to establish a connection with the MLB-S4101. This in turn will allow communications with the
connected serial device in the same manner as a device connected to the COM port on a PC. The LAN becomes
transparent to the serial device and the software running on the PC.
The MLB-S4101 can be configured as a TCP or UDP Client/Server. In direct IP and virtual COM modes, MLB-S4101
should be configured as a server. MLB-S4101 also offers a Heart Beat feature to insure a reliable communications
connection.
