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

•or using the external keyboard wedge KS-20 inside of an EEx d enclosure
•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.
