PART 1

INTRODUCTION

1.1 Safety and EMC Considerations

The instrument is a Class III device (10 to 32 VDC).
Always use a power supply, which complies with EN 60950 safety standard.

EMC Considerations

• Whenever EMC is an issue, always use shielded cables.

• Never run signal and power wires in the same conduit.

• Use signal wire connections with twisted-pair cables.

• Install Ferrite Bead(s) on signal wires close to the instrument if EMC problems persist.

Failure to follow all instructions and warnings may result in injury!

1.2 Before You Begin

Inspecting Your Shipment:

Remove the packing slip and verify that you have received everything listed. Inspect the
container and equipment for signs of damage as soon as you receive the shipment. Note
any evidence of rough handling in transit. Immediately report any damage to the shipping
agent. The carrier will not honor damage claims unless all shipping material is saved for
inspection. After examining and removing the contents, save the packing material and
carton in the event reshipment is necessary.

Customer Service:

If you need assistance, please contact the Customer Service Department nearest you.

Manuals, Software:

The latest Operation Manual as well as free iSeries configuration software and iServer
Mail Notifier are available at the website listed on the cover page of this manual or
on the CD-ROM enclosed with your shipment.

1.3 Description

This device can be purchased as a stand alone DIN Rail mounted unit, or
as an option for an iSeries monitor/controller (Embedded Ethernet Server)
with a RS485 communication port interface. Some iSeries
monitors/controllers do not utilize RS485 communications. In such
models, the RS485 instructions do not apply.

The iServer is a stand alone Ethernet Server designed to connect industrial devices with
serial interfaces to the Ethernet network using the TCP/IP protocol. It contains an
Ethernet Server and RS-232/485/422 interfaces.

The standard features include:

• Use standard Web Browser (TCP/IP protocol) or HTTPGET DOS program for network
connectivity.

• Install via RS-232/485/422 serial port connection.

• Transfer data from RS-232/485/422 serial interface to TCP/IP using built-in socket
server.

• Use a standard home page or customize web page using special applets, which are
available on our website.

The following example illustrates how you can hookup the devices with serial interface
on the net using the iServer:

2.1 Physical Characteristics and Mounting of DIN Rail Unit

Figure 2.1 iServer Dimensions and Mounting

Mounting on DIN Rail (refer to the Figure 2.1)

To install unit onto DIN Rail:
a) Tilt unit, position adapter guide onto DIN Rail.
b) Push unit towards DIN Rail and it will snap into place.

Removal of unit

The adapter can remain on DIN Rail and the iServer can be removed.
a) While holding the adapter, push unit upwards and the unit will detach from the

adapter.

2.4 Serial Communication Interfaces

Two communication interfaces are supported in the iServer: RS232 and RS-485. These
standards define the electrical characteristics of a communication network. The RS485
port of the iServer is fully compatible for use with RS422 instruments. The RS485 is an
extended version of the RS422 communication standard which increases the allowable
number of devices from 10 to 32 by improving the electrical characteristics.

The iSeries controller/monitor with the embedded iServer option board support
only RS485/422 interfaces.

• The RS232 standard (point-to-point) allows a single device to be connected to an
iServer. The iServer operates with full-duplex RS232 using three wires: an
Rx-receives wire, an Tx-transmits wire, and a common ground wire. RS232 cable
length is limited to 50 feet.

• The RS485 standard (multi-point) allows one or more devices (multi-dropped) to be
connected to the iServer using a two-wire connection (half-duplex) +Rx/+Tx and
–Rx/-Tx. Use of RS485 communications allows up to 32 devices to connect to the
iServer with cable length up to 4000 feet long.

Although the RS485 is commonly referred to as a "two wire" connection, the
iServer also provides a ground/return shield connection to use as a common
connection for EMI noise protection.

Table 2.2 shows the differences between RS232 and RS485 communication interfaces.

Table 2.2

Data Transmission Characteristics RS232 RS485

Transmission Mode Single ended Differential
Electrical connections 3 wire 2 wire
Drivers per line 1 driver 32 drivers
Receivers per line 1 receiver 32 receiver
Maximum data rate 20k bits/s 10M bits/s
Maximum cable length 50 ft (15 meters) 4000 ft (1200 meters)

Changing between RS232 and RS485 interfaces, as well as modifying the other
parameters is possible through the iServer home page (see Part 5 for details).

2.4.2 Wiring RS485 Interface

RS485 interface uses a two-wire communication system (one for transmitting and one for
receiving) plus a common wire to connect to the shield of the cable. It is recommended
to use a shielded cable with one twisted pair.

Use of twisted pair and shield will significantly improve noise immunity.

Figure 2.5 shows multi-point, half-duplex RS485 interface connections for the iServer.

Figure 2.5 Multi-point, Half-Duplex RS485 Wiring

Value of the termination resistor is not critical and depends on the cable
impedance.

with RS485 communication interface.
