1. INTRODUCTION
References to NCOM-113-M in this document represent NCOM-113-M, NCOM-112-M
and NCOM-111-M, unless stated otherwise.
NCOM-113-M is a network-based serial device server. It is designed to control your
serial devices located virtually anywhere through a TCP/IP or UDP/IP network
connection. The serial device server can map TCP/IP connections and UDP
broadcasts to a virtual serial port. Applications include accessing a faraway device for
functions such as remote control and data transmission. NCOM-113-M serves as a
transparent virtual serial port without limitations on operating systems and
distances. The virtual serial port redirection uses the protocol known as RFC2217.
NCOM-113-M supports several operation modes, including Driver mode, RFC2217
Server/Client mode, Pair Connection mode, TCP Server/Client mode and UDP mode.
It also supports Windows virtual serial port driver, allowing you to add a virtual serial
port in your Windows system to work over a TCP/IP network. The virtual serial port
functions as a native Windows COM port and is compatible with Windows serial
communication applications. It is installed in the Device Manager of the operating
system. This in turn will allow communications with the connected serial device in
the same manner as a device physically connected to the COM port on a PC. The
serial port supports high serial speeds up to 921.6Kbps in RS-232 for NCOM-111-M,
RS-422/485 for NCOM-112-M, and RS-232/422/485 for NCOM-113-M only.
NCOM-113-M serial device server supports automatic IP configuration protocol
(DHCP) and fixed static IP configuration via the handy web browser console. NCOM-
113-M provides a utility software for Windows, called NCOM Virtual Serial Port
Manager. This program can detect, manage and configure NCOM serial device server
in your network.
This manual covers three different models of one-port serial device server:
NCOM-111-M
RS-232
NCOM-112-M
RS-422/485
NCOM-113-M
RS-232/422/485
In general, the software installation and operation is the same on all models, except
for the different software settings for the configuration of serial operation modes on
NCOM-111-M and NCOM-112-M.
