Page 2 highlights

Standard Serial Tunneling Serial Tunneling is the encapsulation of serial data into network packets, and the transport of the data over a A network. Typical applications (example A) for Serial Tunneling are remote configuration, programming, monitoring and management of industrial devices. Where Windows® based Personal Computers (PCs) are used, an Ethernet adapter and Comm Port Redirector™ software may be used in place of a Device Server. Redirector allows the creation of virtual serial ports (64 maximum), which can be mapped to remote Device Servers on the network. Redirector is shipped with all Lantronix Device Servers. Redirector (example B) allows one COM-port to be B mapped to the PLC, while another is mapped to the Variable Speed Drive. In this application, Serial Tunneling is transparent to the connected devices as well as the respective application software. In some cases, Standard Serial Tunneling may not be adequate to accommodate protocols with strict timing requirements or those that are sensitive to brief gaps in the serial data transmitted. Multi-Master Multi-Master (example C) is the ability to allow access to a single serial device from multiple locations on a C network simultaneously. To implement Multi-Master functionality, the Device Server requires specific knowledge of the communication protocols involved. This knowledge is required to detect the framing of serial requests, their acknowledgement, the processing of responses and the proper queuing of requests. From the user's perspective, Multi-Master support means that information in the connected device can be accessed anywhere a network connection is available. Outgoing Message Mapping D For devices that support non-solicited requests, Outgoing Message Mapping (example D) allows these messages to be sent over the network to a remote device. In each Device Server, a mapping table ensures proper message routing. Requests from the originating device can be directed to any other device on the network, facilitating peer-to-peer communications.

Standard Serial Tunneling
Serial Tunneling is the encapsulation of serial data into
network packets, and the transport of the data over a
network.
Typical applications (example A) for Serial
Tunneling are remote configuration, programming,
monitoring and management of industrial devices.
Where Windows® based Personal Computers (PCs) are
used, an Ethernet adapter and Comm Port Redirector™
software may be used in place of a Device Server.
Redirector allows the creation of virtual serial ports
(64 maximum), which can be mapped to remote Device
Servers on the network.
Redirector is shipped with all
Lantronix Device Servers.
Redirector (example B) allows one COM-port to be
mapped to the PLC, while another is mapped to the
Variable Speed Drive.
In this application, Serial
Tunneling is transparent to the connected devices as
well as the respective application software.
In some cases, Standard Serial Tunneling may not be
adequate to accommodate protocols with strict timing
requirements or those that are sensitive to brief gaps in
the serial data transmitted.
Multi-Master
Multi-Master (example C) is the ability to allow access
to a single serial device from multiple locations on a
network simultaneously.
To implement Multi-Master functionality, the
Device Server requires specific knowledge of the
communication protocols involved.
This knowledge
is required to detect the framing of serial requests,
their acknowledgement, the processing of responses
and the proper queuing of requests.
From the user's perspective, Multi-Master support
means that information in the connected device can be
accessed anywhere a network connection is available.
Outgoing Message Mapping
For devices that support non-solicited requests,
Outgoing Message Mapping (example D) allows
these messages to be sent over the network to
a remote device.
In each Device Server, a mapping table ensures
proper message routing.
Requests from the
originating device can be directed to any other
device on the network, facilitating peer-to-peer
communications.
