Description
Product Overview
The Device Server features complete Ethernet and
TCP/IP network support that allows devices in
industry with RS-232/422/485 connectors such as
milling machines, measurement instruments, and
robots to connect to LAN based automation. Other
devices typically found on campus networks such as
card readers, code readers, lab equipment, medical
equipment, and other similar serial devices can now
instantly migrate to a TCP/IP network. Additionally, by
deploying the device server, enable users to monitor
and manage up to 256 serial devices from single PC
with the help of Serial IP Redirector software.

3 Installation
To install your Device Server, please see the following
procedures:
•Location
•Desktop Installation
•Powering On Unit
•Connecting Copper Cables
•DB9 Male Connector Pin Assignment
•Serial Connection
•Ethernet Connection

Location
The location selected for installing the Device Server
may greatly affect its performance. When selecting a
site, we recommend considering the following rules:
1. Install the Device Server in a fairly cool and
dry place. See Technical Specifications for
the acceptable temperature and humidity
operating ranges.
2. Install the Device Server in a location free
from strong electromagnetic field generators
(such as motors), vibration, dust, and direct
exposure to sunlight.
3. Leave at least 5cm of space at the front and
rear of the unit for ventilation.
4. Affix the provided rubber pads to the bottom
of the Device Server for grip, and to protect
the case from scratching.

10
Wall Mount Installation
The Device Server can also be installed by wall
mounting. The backside casing provides space for
two screws each side. Identify the exact location at
wall by placing the Device Server and marking the
screw positions. Use the screw (include in the
package) and snug them well to fix the Device Server.
Din Rail Mount Installation
The aluminum DIN Rail attachment plate should
already be affixed to the back panel of the Device
Server. If you need to attach the DIN Rail plate,
assure that the stiff metal spring is situated towards
the top. Attaching the Device Server to the DIN rail is
easy, just align, and attach the top rail, then press
down and snap forward the Device Server to snap in
the bottom rail, as shown in the figures below.
Use following steps set up the Device Server:

11
•The surface must support at least 500 gm for the
Device Server.
•The power outlet should be within 1.82 meters (6
feet) of the Device Server.
•Visually inspect the power adapter and make sure
that it is properly connected.
Make sure that there is proper heat dissipation from
and adequate ventilation around the Device Server.
Do not place heavy objects on the Device Server.
Warning Please exercise caution when using power
tools. Also, install this unit away from damp or wet
locations, or in close proximity to very hot surfaces.
These types of environments can have a detrimental
effect on the unit and cables.

12
Powering On Unit
The Device server uses external power supply 9~32V
DC @ 0.8A 50~60 Hz.
1. Insert the power cable plug directly into the
receptacle located at the back of the device.
2. Plug the power adapter into an available socket.
3. Check the rear-panel LEDs as the device is
powered on to verify that the Power LED is lit. If
not, check that the power cable is correctly and
securely plugged in.
Note: For International use, you may need to change the AC
power adapter cord. You must use a power cord set that
has been approved for the receptacle type and electrical
current in your country.

13
Connecting Copper Cable
The 10/100BASE-TX RJ-45 Ethernet port fully
supports auto-sensing and auto-negotiation.
1. Insert one end of Category 5 twisted pair cable
into an available RJ-45 port on the Device Server
and the other end into the port of the network
node.
2. Check the corresponding port LED on the Device
Server to make sure that the connection is valid.
(Refer to LED chart in next section)
NOTE:
The RJ-45 port accepts both ‘straight-through’ and ‘cross-over’
Ethernet cables without the need to re-configure the port.

Serial Connection
This Device Server features DIP switches on the rear
panel that sets the unit to the correct type of cable
configuration to support connection with a RS-232 /
422 / 485 device.
Definition of DIP Switches
No Dip description Default
1 ON: Console / OFF: Data OFF
2 RS-232 ON
3 RS-422 / 485 (4W) OFF
4 RS-485 (2W) OFF
5 NA OFF
6 NA OFF
7 TMR (Terminator) OFF
For setting the control function of the serial port, see
the table below:
DIP 1 Serial Connection
ON RS-232 Console
OFF Data Communication
NOTE:
1. If using console mode turn the DIP Switch 1 to ON position.
For data communication from the serial device keep the switch
to OFF position. In case of ON position data communication
will be blocked and at OFF position console port access.
2. For some RS-422/485 devices, which may not be designed to
provide DB-9 connection, please check the pin definition to
connect the devices.
3. For the first time installation, you have to use console mode to
setup the IP and TCP port configuration with RS-232 cable.
