2 Introduction
1 Overview
The NetCom Plus Serial Device Servers are designed to remotely operate serial ports over networks.
The network interface is implemented as a modern Gigabit / Fast Ethernet with Auto-MDI(X).
The subfamily of NetCom Plus with WLAN option Serial Device Servers provide a second network
interface for WLAN (as of 802.11 b/g/n) with up to 150 Mbit/s transfer rate. The subfamily of
NetCom Plus POE Serial Device Servers may use power supply by Power-over-Ethernet function,
as an alternative to a standard DC supply.
The data transport is implemented via TCP/IP and UDP protocols. Therefore control is available
via WLAN, Ethernet, Intranet and Internet. All communication with the NetCom Plus Servers
may happen encrypted by SSL on all interfaces.
The supplied driver software implements virtual serial ports, which hide the network transfer from
your applications. Software applications using standard COM ports need no change to operate via
NetCom Plus through the virtual serial ports.
The NetCom Plus Serial Device Servers are also referred to as “NetCom
+
” for brevity.
This
abbreviation is used in this manual, when the description of a function or property is more general.
2 Introduction
This manual covers several different models of NetCom Plus devices. In general the operation is
the same on all models, except where explicitly noted otherwise. All models are available with an
option for Wireless LAN.
The devices come with a steel case well suited for industrial environments.
The NetCom Plus support high serial speeds up to or possibly above 3 Mbps. All serial ports
provide communication via the common RS 232 mode (up to 1000 kbps).
They also offer the
industrial RS 422 and RS 485 configuration (up to 3.0 or 3.7 Mbps). In RS 485 mode the NetCom
+
will use the Automatic Receive Transmit (ART) control logic to follow the RS 485 specifications
for transmitting data. No special code for data direction is necessary to be implemented in your
software applications.
Applications requiring RS 232 only are in widespread use. For ease of configuration several models
of NetCom Plus only support this serial operation. The names of these models end with an ‘11’.

2.1 About this Manual
This manual covers many configuration options of the NetCom Plus Serial Device Servers. The
vast majority of these are set by software, sometimes in alternative methods. To emphasize these
in the text, special character styles are used.
Bold Typewriter
is used for the names of configuration options or buttons, as they
are displayed in menus or dialogs.
Typewriter
denotes names of special values for multiple-choice parameters. Such
values may appear in drop-down lists or as radio buttons.
