Introduction
The MD-N32 is a Serial to Ethernet Gateway. One MD-N32 unit is
required (unless it is connected to a Rosslare software product that
supports direct TCP/IP operation, in which case the PC's internal LAN
card may be used).
A Serial to Ethernet Gateway allows connectivity for systems with
Legacy serial interface communication, such as RS-232 or RS-485,
with local networks and Internet.
The concept is to send and receive information between varied PC-
managed products (access control systems, guard control, security
systems, and so on) via a local network or Internet, thereby saving on
serial cabling installation, and enabling connections to remote sites
(most modern offices are already networked).
As a compact plug-in module, the MD-N32 can easily connect to
most products without modification. The module receives serial
communication, converts it to TCP/IP format, and sends it over the
LAN or Internet to the PC. From the other end, the module converts
communications sent from the PC over the network back to serial
format into the device.
All the setting and configuration is done using the AS-IP01
Configuration Utility PC software or by other Rosslare software that
supports a direct connection to hardware through TCP/IP (refer to the
software manuals of the specific products.) Once the module is
configured, the information is saved in a non-volatile memory within
the module.
The MD-N32 has two indication LEDS – the green LED indicates LAN
connectivity (Link) and the red LED indicates power supply operation
(Power).
