1 Introduction
The iSOLATE100 is an ATEX certified intrinsically safe PS2 and serial interface
suitable for industrial use. The device allows connection of hazardous area
peripherals such as pointing devices, keyboards and scanners to PC systems located
in a safe area. The iSOLATE100 is designed for use with Extronics own range of
keyboards and pointing devices such as trackball, trackpad or finger mouse but can
be used with other manufacturers compatible equipment.
The iSOLATE100 is certified allowing connection of peripheral devices in Zone 1 & 2
hazardous locations.
The unit is simple to operate and is available in a variety of configurations as
specified in the ordering data below.
With both galvanic and optical isolation for the power and the interfaces no high
integrity earth is required or consideration about potential differences occurring
meaning low simple and trouble free installation.
Keyboard or pointing device may be up to 20 metres away from the PC in the
hazardous area using a PS2 cable or up to 70 metres using a CAT6 STP cable

3 Installation and Setting-to-Work
3.1 Operation
The iSOLATE100 supports both PS/2 mouse and keyboard interfaces, the
iSOLATE100 can support other alternative interface options including RS-232 and
RS485 provided they are specified when ordered.
3.2 Installation
The unit is simply installed in a safe area, with the PC connected on the safe area
connections & the hazardous area devices connected to the hazardous area
connection, as shown in the drawings below. The iSOLATE100 can be configured in
4 modes these are detailed below.
NOTE
Modes can only be configured by Extronics.
3.3 Version EX01
The EX01 variant provides the capability to connect one EExi keyboard and/or one
EExi pointing device. These can be connected to either the screw terminals or the
PS/2 ports on the iSOLATE100.
The PS/2 connection sockets or screw terminals connect to the PC in the safe area.
All leads and terminals are included.

PS/2 scanner connections with version EX01:
An EExi PS/2 Scanner such as the iSCAN100 can be connected on the hazardous
side of the iSOLATE instead of a keyboard. In this configuration the mouse may or
may not be connected.
Since a PC does not detect a barcode scanner as a keyboard, the PC may discard
the scanner’s signals by switching off the keyboard channel after booting. In this
case, please cancel the keyboard test in the BIOS settings of your PC or wire a
keyboard in parallel to the scanner. Different ways of doing this are shown below;
•using the screw terminals wired in parallel with the PS/2 terminal on the
hazardous side

•by using a keyboard wedge in the safe area
Furthermore, you may connect a keyboard to the safe side of iSOLATE100 using its
built-in keyboard wedge. Please refer to version Ex02.
Information A Keyboard wedges connects 2 devices to a single channel. Using a
keyboard wedge is effectively like connecting and disconnecting devices
repeatedly. Not every PC will accept this, wiring the scanner and
keyboard in parallel is often the more reliable solution.

3.4 Version EX02
The EX02 variant provides the capability to connect an EExi keyboard and/or
pointing device in the hazardous as well as a safe keyboard and/or pointing device in
the safe area. This is due the internal keyboard wedge of the iSOLATE100 which is
configured such that it connects both sides of the iSOLATE100 in parallel, including
the EExi screw terminals.
You can use a PS/2 scanner instead of a keyboard, however most PCs need a
keyboard while booting. To avoid this, please refer to the solutions explained in
version Ex01.

3.5 Version EX03
The EX03 variant provides the capability to connect an EExi RS-232 barcode
scanner, such as the iSCAN100, in the hazardous area. The scanner must be
connected to the iSOLATE100’s mouse port even if there is no keyboard connected.
This is because of the internal circuit to the RS-232 output terminals. The EExi PS/2
and screw terminals are wired in parallel so either can be used.
The PS/2 sockets for the keyboard and mouse in the safe area are internally wired to
the keyboard wedge circuit, however the keyboard wedge is not activated (which
makes PC communication easier). Should the keyboard wedge need to be activated
please see EX02.
Information A Keyboard wedges connects 2 devices to a single channel. Using a
keyboard wedge is effectively like connecting and disconnecting devices
repeatedly. Not every PC will accept this, wiring the scanner and
keyboard in parallel is often the more reliable solution.

3.6 Version EX04
The EX04 variant provides the capability to connect an EExi RS-232 barcode
scanner, such as the iSCAN100, in the hazardous area. The iSOLATE100 converts
the RS-232 signals to RS-485 and transmits this to the PC. The scanner must be
connected to the iSOLATE100’s mouse port even if there is no keyboard connected.
This is because of the internal circuit to the RS-232 output terminals. The EExi PS/2
and screw terminals are wired in parallel so either can be used.
The PS/2 sockets for the keyboard and mouse in the safe area are internally wired to
the keyboard wedge circuit, however the keyboard wedge is not activated (which
makes PC communication easier). Should the keyboard wedge need to be activated
please see EX02.

3.7 iSOLATE100M
The iSOLATE100M has been certified ATEX II 2 G EEx m [ia] IIC T4, II D T75°C
IP67 for use inside the hazardous area. The unit can be supplied with 2 junction
boxes connected to the iSOLATE100M via 1.5m of cable at each end as shown
below;
or with flying leads. The iSOLATE100M has the same configuration options as the
iSOLATE100 (e.g. iSOLATE100EX03) which must be specified when ordering.
3.8 Operation
Once all connections have been made, switch on the PC and check that all of the
peripheral devices (keyboard, barcode scanner or pointing device) are functioning
correctly.

4 Intended Purpose Usage
Important Before setting the units to work, read the technical documentation
carefully.
Important The latest version of the technical documentation or the corresponding
technical supplements is valid in each case.
The iSOLATE00 is built using modern components and is extremely reliable in
operation; however it must only be used for its intended purpose. Please note that
the intended purpose also includes compliance with the instructions issued by the
manufacturer for installation, setting up and service.
Any other use is regarded as conflicting with the intended purpose. The manufacturer
is not liable for any subsequent damage resulting from such inadmissible use. The
user bears the sole risk in such cases.
4.1 Transportation and Storage
All iSOLATE100 devices must be so transported and stored that they are not
subjected to any excessive mechanical stresses.
4.2 Authorized Persons
Only persons trained for the purpose are authorized to handle the iSOLATE100; they
must be familiar with the unit and must be aware of the regulation and provisions
required for explosion protection as well as the relevant accident prevention
regulations.
4.3 Cleaning and Maintenance
The iSOLATE100 and all its components require no maintenance. All work on the
iSOLATE100 by personnel who are not expressly qualified for such activities will
cause the Ex approval and the guarantee to become void.
The iSOLATE100 does not require any active maintenance, do not attempt to open
the iSOLATE100 to repair the unit, otherwise the iSOLATE100 may not comply with
the ATEX regulations.
It is recommended that the iSOLATE100 is regularly inspected for deterioration
caused from wear and tear, accidental damage, and corrosion by chemicals etc. This
is to ensure the integrity of the protection is maintained at the intended level of
security from ignition in compliance with ATEX regulations.
Should you be in any doubt about the integrity of your keyboard then please return it
to Extronics for inspection.

4.4 Safety Precautions
Important For the installation, maintenance and cleaning of the units, it is
absolutely necessary to observe the applicable regulations and
provisions concerned with explosion protection (EN 50014, EN 60079-
14:2003) as well as the Accident Prevention Regulations.
4.5 Cleaning and Maintenance Intervals
The cleaning intervals depend on the environment where the system is installed.
4.6 Aggressive substances and environments
The iSOLATE100 is not designed to come into contact with aggressive substances or
environments, please be aware that additional protection may be required.
4.7 Exposure to external stresses
The iSOLATE100 is not designed to be subjected to excessive stresses e.g.
vibration, heat, impact. Additional protection is required to protect against these
external stresses.
The iSOLATE100 will require additional protection if it is installed in a location where
it may be subjected to damage.
