ESDS-101

1 Port RS232/485/422 Ethernet Serial Device Server

The ESDS-101 Ethernet serial server connects RS-232, 422, 485 serial devices to an Ethernet LAN/WAN providing a reliable communication connection. The ESDS-101 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 ESDS-101. This in turn will allow communications with the connected serial device in the same manner as a device connected to the COM port in a PC. The LAN becomes transparent to the serial device and the software running on the PC. ESDS-101 also offers a Heart Beat feature to insure a reliable communications connection.
The ESDS-101 can be configured as a TCP Client/Server or UDP. The ESDS-101 operates in “Direct IP Mode”, “Virtual COM Mode”, and “Paired Mode”.

DIN rail or Panel mount. Supports 10/100 Mbps Ethernet. Supports RS-232, RS-422, and RS-485 serial interface. Supports LAN and WAN communications. In Server mode supports individual client sessions for security. Management access password protected. Virtual COM drivers for Windows NT/98/ME/2000/XP.

Supports socket connection, TCP server, TCP client,   and UDP. Supports up to 8 TCP connection in TCP server mode. Heart beat connection ensures reliable TCP connection against power failure or network disruption. Supports loop back mode. Data is echoed back for easily testing the connection.

Operation modes

 Direct IPode

Direct IP connections allow applications using TCP/IP or UDP/IP Includes network socket programs to communicate with the asynchronous serial port on the ESDS-101. In this type of application the ESDS-101 is configured to TCP or UDP server. The socket program running on the PC establishes a communication connection with the ESDS-101. The raw data is sent directly to and from the serial port.
