Work Mode
Console Management
Console Management mode is the most common Work Mode used, allowing
users to establish Telnet or SSH sessions to the Serial Console Server to
manage the serial devices. In this mode users can log in using the web
browser’s built in SNViewer application via
Telnet or SSH ; remotely via Telnet
or PuTTY; or directly using the HyperTerminal or SNViewerUSB
applications.
Note: Be sure that the Socket entry specified on the Network page corresponds
to the port that the device listens on. 5001 is the Serial Console Server’s
default setting (see
Network , page 95, and Base Socket , page 96).
Real COM Port
This mode is used in conjunction with a virtual COM port driver installed on
the remote user’s local computer. When the Serial Console Server’s COM port
is set to this mode, the device connected to the port appears as if it were a
device directly connected to a COM port on the remote user’s local computer.
This mode is useful with devices such POS terminals, Bar Code Readers, Serial
printers, etc. since it allows you to use software that was written for pure serial
communication applications. It can be used with other ALTUSEN
management products, such as the PN5/PN7 Power Over the NET™.
The Serial Console Server comes with Real COM drivers for Windows
systems and TTY drivers for Linux systems.
TCP Server / TCP Client
TCP (Transmission Control Protocol) provides a reliable transport layer for
transmitting serial data over the TCP protocol via socket programming.
TCP Server (RAW TCP)
In TCP Server (RAW TCP) mode, data transmission is bidirectional. In this
mode, the host computer initiates contact with the Serial Console Server and
requests a connection to its serial port.
Once the connection is established, the host receives data from the serial
device. From this point on, data can be transmitted between the host and the
device in both directions.128-bit/256-bit SSL (TLS v1.0 / TLS v1.1 / TLS v1.2)
data encryption is supported in this operating mode.
