RADIO FREQUENCY INTERFERENCE STATEMENTS
This equipment generates, uses, and can radiate radio-frequency energy, and if not
installed and used properly, that is, in strict accordance with the manufacturer’s
instructions, may cause interference to radio communication. It has been tested
and found to comply with the limits for a Class A computing device in accordance
with the specifications in Subpart B of Part 15 of FCC rules, which are designed to
provide reasonable protection against such interference when the equipment is
operated in a commercial environment. Operation of this equipment in a
residential area is likely to cause interference, in which case the user at his own
expense will be required to take whatever measures may be necessary to correct
the interference.
Changes or modifications not expressly approved by the party responsible
for compliance could void the user’s authority to operate the equipment.

PURE NETWORKING RS-232/422/485 TO TWISTED-PAIR DEVICE SERVER
2. Overview
2.1 Introduction
The Pure Networking™ RS-232/422/485 to Twisted-Pair Device Server provides an
RS-232/422/485 point-to-point connection over twisted-pair cabling. Each
connected device has an RS-232/422/485 interface. The servers enable industrial
serial devices 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.
The server has one RJ-45 connector for linking to twisted-pair cable.
The server works in 2-wire half-duplex (RS-485) and 4-wire full duplex (RS-422/
485) asynchronous serial data transmission modes at data rates of up to 115.2 kbps.
And it gives you extended distances up to 0.8 miles (1.2 km) over 24 AWG using
RS-422/485.
A handy terminator feature improves signal quality and distance. Plus, LEDs give
you device status at a glance.
2.2 Components
The server’s front panel is shown in Figure 2-1. LED indicators display the server’s
and the network’s status. Table 2-1 describes the server’s front-panel indicators and
connectors. The numbers in Figure 2-1 correspond to the numbers in Table 2-1.

CHAPTER 3: Installation
3. Installation
3.1 Location
The location you select to install the server may greatly affect its performance.
When selecting a site, consider the following rules:
1. Install the server in a fairly cool and dry place. See Chapter 1 for the
acceptable temperature and humidity operating ranges.
2. Install the server in a location free from strong electromagnetic field
generators (such as motors), vibration, dust, and direct exposure to sunlight.
3. Leave at least 3.9" (9.9 cm) of space at the server’s front and rear for
ventilation.
3.2 Installing the Server
Follow the instructions listed below to install the server on a desktop.
1. Place the server in a clean, flat, safe position with easy access to AC power.
2. Affix the four self-adhesive rubber feet to the server’s underside.
3. Plug the server’s AC power adapter into an available wall socket. (The green
Pwr LED on the rear panel should light.)
4. Connect cables from the network devices to the server’s front-panel ports.
(The green LNK LED should light.)
You can also mount the server vertically (for instance, on a wall). Simply use the
server’s underside as a template to measure and mark the holes’ position onto the
surface where you will install the server. Then use the two screws provided to
mount the server firmly in place.
WARNING
Install the server away from damp or wet locations, and away from very
hot surfaces. These environments can have a detrimental effect on both
the server and the cables. An ideal location is a cool, dry environment
such as a typical equipment room.

16
PURE NETWORKING RS-232/422/485 TO TWISTED-PAIR DEVICE SERVER
3.3 Powering On the Unit
The server uses a 12-VDC, 0.8-amp, 50–60-Hz external power supply.
1. Plug the power adapter’s cable directly into the connector on the server’s
back panel.
2. Plug the other end of the power adapter into an available wall socket.
3. As the server is powered on, verify that the Pwr LED is lit. If not, make sure
the power cable is correctly and securely plugged in.
3.4 Connecting Copper Cables
When connecting copper cable to the server’s 10/100BASE-TX port, be sure that
you use the correct type of connector (RJ-45). Follow the steps below to properly
connect copper cable.
1. Insert one end of Category 5 twisted-pair cable into an available RJ-45 port on
the converter and the other end into the network node’s port.
2. Check the corresponding port LED on the converter to make sure that the
connection is valid. (Refer to Chapter 4.)
3.5 Connecting to the DB9 Connector
Figure 3-1 illustrates the server’s DB9 connector.
