Chapter 6. Port Operating Modes
65
The COM port of one of the two units connects to the COM port of a computer,
while the COM port of the other unit connects to the serial device to be
accessed.
The two units then communicate with each other via their IP and port
addresses, and supports SSL data encryption. The port address is set by the
Base socket entry on the General Settings page. See General, page 39, for
details.
UDP Mode
UDP (User Datagram Protocol) Mode is faster and more efficient at
communications than TCP. In UDP mode, communications are bilateral. A
serial device can send data to, and receive data from, up to 16 host computers
via the Secure Device Server’s COM port.
Because it doesn’t perform error checking in the thorough way that TCP does,
UDP is more suitable for real time applications (such as message display) than
the slower TCP, which is optimized for data accuracy.
Console Management
Console Management allows users to establish Telnet and/or SSH sessions to
the Secure Device Server for managing and controlling the serial devices
connected. Users can log in using Java SNViwer application via Telnet or SSH,
or remotely via Telnet, SSH, or PuTTY.
