2 Important Notes
This document is intended to provide customers with brief descriptions on the product and
to assist customers to get started.
FCC warning
Class A for Ethernet Serial Server (Model SE5001) and for 1-
port Modbus Gateway (Model MB5001C)
This equipment has been tested and found to comply with the limits for a Class A digital device
pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in a commercial environment. This
equipment generates, uses and radiates radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference in which
case the user will be required to correct the interference at his own expenses.
A shielded-type power cord is required in order to meet FCC emission limits and also to prevent
interference to the nearby radio and television reception. It is essential that only the supplied power
cord can be used.
Use only shielded cables to connect other devices to this equipment by RS-232 or RS-485 ports.
Be cautioned that changes or modifications not expressly approved by the party responsible for
compliance could void ones authority to operate the equipment.

3 Electrical connections
3.1 Installation Procedures
Connect SIUTCP2/SIUTCP3 to power supply (9-30V AC/DC) using the special universal power
adaptor included in the box with SIUTCP2/SIUTCP3.
3.2 Connecting the Ethernet LAN adaptor to a PC
Connect the SE5001 to the Ethernet network through the Ethernet cable (please, use a standard
straight-through Ethernet cable if the converter is connected to a hub/switch, while a cross-over
Ethernet cable if the converter is connected directly to one’s PC. In this case it is necessary to
make sure the PC to be in the same Ethernet network of the converter;

IMPORTANT NOTE: the device is provided with a RESET button which restores the system at its
basic factory defaults.
3.3 Connecting the RS-485 ports to a serial RS-485 network
Connect the SE5001 or the MB5001C’s serial port to a serial device;
The connection to a serial RS-485 bus must be done following the relevant best practices. Please,
read the appendix “Modbus over serial line guidelines” at the end of this document.
An RS-485 network installed or operated without following the relevant prescriptions and guidelines
can cause problems to data communication and damages to the connected devices.
IMPORTANT NOTE: Both the converters have been tested ONLY with the 2-WIRES RS-485 and
the RS-232 connection.

4 SIUTCP2/3 configuration
4.1 Configuration steps
The default settings present on the converter are equal and shown in the table below:
Default Setting Default User Name & Password
IP: 10.0.50.100 User Name: admin
Gateway: 10.0.50.254 Password. Null (leave it blank)
Subnet: 255.255.0.0
Below you can find the sequence of steps to follow for a complete configuration of the converter.
•Set a new IP address on the converter
It is possible to set a new IP address on the converter by modifying your current PC network
parameters;
The new IP address which is necessary to define on the PC, has to belong to the same octet of the
default IP address set on the converter; the Subnet Mask and Gateway have to be exactly the
same ones defined on the converter.
Please, note that in this case the PC has to be completely disconnected from the Network LAN
You can do it using two different wiring connections:
•by connecting the PC directly to the converter through a cross-over Ethernet cable (for a
easier set-up)
•by connecting both the PC and the converter to a switch/hub using a standard straight-
through Ethernet cable
Once the PC network settings have been changed as described above, you can try to ping
the converter in order to check if the communication between the PC and the converter is
present.
•Install the Serial Manager Software (SIUTCP2) or the DeviceView software (SIUTCP3)
which come with the CD included in the box and run it.
•
IMPORTANT NOTE: The operation and settings of both the software are exactly the same, except
for the settings of the COM Port. Below you will find the ones related to settings of the Network
using the Serial Manager one: Later on, when dealing with the configuration of the COM port, both
of the software will be shown.
If the settings of your PC have been set correctly, the following window will appear:
