General Information
1 Functional Description
The interface series TW-100D... and TW-115B isolates a PC in the safe area
electrically from a keyboard, a mouse or other PS/2 or RS232/RS485-devices
in the Ex area. This separation concerns the signal lines as well as the power
lines. Therefore these devices do not need to be connected to ground. TW-
100D or TW-100DB and TW-115B are mounted in the safe area, while TW-
100Dmor TW-100DBmmay be mounted inside of the Ex area as well.
The connected devices inside of the Ex area have to be approved for intrinsic
safety and match the data for intrinsically safe circuits in chapter 5. There are
two versions concerning this electrical data (type name with or without "B"),
see table below.
RS232 data can be translated and sent to the safe area as RS485 data to the
safe area in order to increase transfer range. This is not possible for the
opposite direction. The transfer range is significantly depending on the cable
type, the baud rate and the electrical distortions.
TW-100D... and TW-115B have a built-in keyboard wedge with one keyboard
and one mouse socket, which makes communication with the PC possible
even from the safe area. Chapter 10 shows sensible connection examples.
TW-1... and the connected PS/2 devices are supplied by the PC. In case of
RS232 or RS485 transmission exclusively the interface can by supplied with
an external plug-in supply, for details see chapter 10.

3 Start of Operation
Observe the safety advices!
•Switch off the PC.
•Connect the cable from TW-1... with the PC (safe area)
•Connect the EEx i keyboard and EEx i mouse or other approved
intrinsically safe devices with the terminals on the EEx i side of TW-1...
•Connect further devices with the safe side terminals of TW-1... if
applicable
•Connect the external plug-in supply with the TW-1... (only for exclusive
RS232 or RS485 transmission)
•Make sure, that the electrical data of connected devices correspond to
the data of the terminals. (E.g. do not connect RS232 devices with PS/2
terminals !)
•Power the PC up and wait for the end of the booting procedure.
Configuration of the PC during booting is only possible from one side of
the interface TW-1... if the keyboard wedge is active, see chapter 10.
4 Operating Hints
•Some PCs can be restarted by pressing a key on the keyboard. In this
case all PS/2 terminals of the PC are supplied even if the PC has been
switched off. Therefore TW-1... and all connected devices are still
active with the PC switched off !
•Do not mix up the mouse and keyboard channels, they are not quite
identical.
•Standard PS/2 leads should not exceed 3 m of length, particularly if
there are electrical distortions. If you need longer cables: more copper
and isolation mean less resistance and capacitance.
•TW-1... sinks about ca. 350 mA from your PC. Devices connected with
the safe side even increase the power consumption. Some laptops
cannot supply TW-1... with sufficient current.
•Power on the EEx i side of the interface is limited. This limits the
amount and the power consumption of the connected devices.
•A PS/2 scanner transmits PS/2 data, but might not answer to a booting
PC like a PS/2 device. If your PC expects a keyboard (BIOS settings) it
will switch off the keyboard clock line, if there is no keyboard to be
found. You may then for example switch a keyboard in parallel to the
base station over an external (KS-20) keyboard wedge or switch the
base station over to the "keyboard wedge mode".
•A keyboard in parallel to a scanner cannot distinguish between the
sources of PS/2 signals and might look at scanner data as PC

TW-100D, TW-100DB, TW-100Dm, TW-100DBm, TW-115B - Technical Documentation
25.9.2007 © E.L.B. Ex-Geräte Bachmann GmbH Page 5
instructions. In this case switch scanner and keyboard in parallel over
an external keyboard wedge (KS-20).
•RS-232 and RS-485 data may only be sent from the Ex-protected base
station to the PC, not in the opposite direction. Transmission of RS-XXX
data from the PC to the terminals of the Ex approved base station are
not allowed and may additionally destroy components.
•Mixing-up of signal types (RS-232 into PS/2 terminals e.g.) or terminals
may destroy internal components. Repair is hardly possible because of
the moulding.
•TW-1... probably contains the only PS/2 wedge, which works even with
mice. Please keep in mind, that swapping different devices connected
to the internal TW-1... wedge causes the same PC reactions like
swapping by hand. Some hints:
oLet your PC boot completely before any action.
oAfter switching on the PC only one side (selectable) of the
keyboard wedge is connected to the PC for 30 seconds. The PC
boots with the devices of this side. Mouse and keyboard of the
other side are electronically disconnected meanwhile. They will
be connected automatically afterwards and introduce themselves
to the PC.
oThe PC boots with the devices connected to the side of TW-1...,
which you selected for this purpose. If devices are missing there
the PC switches all PS/2 lines dead.
oThe keyboard wedge switches over automatically, which you will
not notice while swapping keyboards. Swapping mice may last
up to 3 seconds, depending on the PC and the mice. Rapid
mouse actions do not accelerate anything.
oSome PCs answer to a new mouse like clicking the right mouse
button: a window is opened. Please press "Esc" or "Alt" or click
on an empty area on the screen with the left mouse button to
close the window.
oFrequent or rapid swapping does not affect TW-1... at all - but
maybe your PC application. (If data strings are interrupted e.g.)
Please keep in mind, that vibrations may move a mouse in
industrial sites.
•Tip: Intrinsically safe circuits are electrically separated from other
circuits up to a peak value of 375 V. Thus intrinsically safe devices
connected there need not be grounded.

10 Connection Examples
TW-100D... und TW-115B in standard version usually connect one keyboard and one
mouse on the EEx i side to a PC on the non-Ex side. TW-100D(B) and TW-115B
must stay in the non-Ex area, TW-100D(B)m may be used inside of the Ex area.
Other than the standard versions may be connected to further keyboards, scanners
with PS/2 or RS-232 outputs and more, and on the non-Ex side data may be
transmitted according to RS-232 or RS-485 standards. Any possible version must be
switched internally by solder bridges.
The following drawings show reasonable connection examples and their respective
ID numbers. If your order does not mention a special ordering number, we supply
you with the standard version. If you are not sure about the correct order number,
please just describe your application and the kinds of plugs you desire.
Inside of Ex-p systems
When used in pressurized apparatus the inner volume of the interfaces must be
purged. For this purpose the side covers of the interfaces can be provided with
orifices on request.
Please note:
Terminals and PS/2 plugs on the Ex side are switched in parallel. So you may connect your devices
with their original PS/2 terminals or a screw terminal to TW-100D..., see also chapter 7: "Dimensions
and Terminals". The following drawings mostly only show the PS/2 plugs.

10.1 TW-100D(B)
ID no.:
TW-100D-KM000-KMMK = standard version
Connection examples:
Standard connection, one keyboard and one mouse or only one of both on the Ex
side. (Shown with PS/2 terminals here, the Combicon screw terminals are internally
switched in parallel.) Cable glands and PS/2 plugs on the non-Ex side.
One mouse and one PS/2 scanner type SK-200 or only one of both on the Ex side.
The scanner transmits data like a PS/2 keyboard therefore the ID number is the
same as in the example above.
Please note: In the BIOS of your PC the keyboard test procedure must be switched off, otherwise the
PC will switch off the PS/2 line, because the scanner does not send an ID code to the PC during
booting. Instead of this you may switch a keyboard in parallel to the scanner over a keyboard wedge
type KS-20.

PS/2 scanner and keyboard are switched in parallel here over the internal connection
between PS/2 and screw terminal, which only works with AT- or XT-keyboards and
the BIOS set to "stand alone keyboard". Modern keyboards will look at data from the
scanner as PC instructions and "answer unasked".
A keyboard wedge type KS-20 inside of an EEx-d enclosure
makes a simultaneous use of scanner and keyboard possible.
KS-20 is not suitable for mice.

Example with KS-20:
Any keyboard terminal
may be connected with
a keyboard wedge KS-
20 instead of a
keyboard, so that PS/2
scanners can be used
there in parallel to a keyboard. Mice are always connected to the mouse terminals, the drawing shows
the integrated mouse (or touchpad or touchpoint) inside of ELB's keyboard TT-100 or TT-110FM. KS-
20 is not suitable for mice.
External devices must not consume more power than TW-100D... or your PC can provide. A separate
power supply on the PC side is possible via a head phone plug, see RS-232 versions.
