6.1 Introduction | ![]() |
![]() | |
|
The Options-menu, as shown on the left, gives access to a number
of options that can be set by the user. The default settings and some
other configurable parameters can be set via Choices... as described
in chapter 7. Please note that some option may be greyed out,
if that option is not available in the currently selected simulation
or if the option has been disabled from Choices....
|
6.2 Sound effects | ![]() |
![]() | |
The first option controls the sound which is on by default.
Whenever a key is pressed, a realistic sound sample is played.
The sound was recorded from a real Enigma M4 by Jim Oram in the USA.
Whenever the sound is considered to be disturbing, e.g. in a class room,
it may be turned off by deselecting this option. You may disable sound
permanently, by deselecting it in Choices....
|
6.3 Realistic movements | ![]() |
![]() | |
The Enigma Simulator tries to mimic the behaviour of the real
Enigma as accurately as possible. Whenever a key is pressed it
takes a little while before the encoding is worked out. This
is exactly how a real Enigma behaves. Pressing a key involves
activating the rotating stepping mechanism of the wheels and
occasionally a turnover on the next wheel. First the mechanism
is moved into the new position and then the ciphering takes
place. A sound is used to illustrate the mechanical process.
Moving the wheels manually with the mouse in the Enigma-window
has the same behaviour as on a real Enigma. Here too a sound
is used to illustrate the movement.
If you don't want this realistic behaviour, you may turn it off by deselecting the option Realistic movements in the Options-menu. If you do so, the encoding process is much faster and the wheels can be moved in place more quickly. If you want to study the behaviour of the Enigma, you may want to leave this option on however. |
6.4 Lamp filter | ![]() |
![]() | |
Some Enigma models were equipped with an optional lamp filter. This is a transparent green filter that can be placed over the lamps on the lamp panel. Locks on the Enigma case were used to keep the filter in place. If available, the option Lamp filter can be used to turn the filter on or off. Alternatively, you may click on the locks in the Enigma-window to do the same. The filter was used to make the encoded letters better readable in bright sunlight. |

6.5 Lamp box | ![]() |
![]() | |
The Swiss K Enigma was equipped with an external lamp box to allow an extra operator to read and write down the ciphered message. Use this option to open/close the extra lamp box. The option is greyed out on models without an external lamp box. Additionally, you may click on one of the 'locks' on the panel to add or remove a green lamp filter. |

6.6 Textured case & Lighter | ![]() |
![]() | |
The are two menu options to control the appearance
of the Enigma's metal case in the Enigma-window. By default
a rather dark metal texture will be used that closely resembles
the actual texture of the Enigma. If Textured case is deselected,
a dark grey colour will be used instead.
Additionally, you may want to tick the option Lighter to make both texture and background colour a little bit lighter. This can be useful if your monitor has a low contrast. |
|
| ||||||||
6.7 Serial input & Serial output | ![]() |
![]() | |
These two options are only available if the serial port is enabled
for use by Enigma. The serial port can be enabled via Choices....
Once the serial port is enabled, you may turn it off temporarily by
deselecting these options. More information about the use of the serial
port is available in chapter 8.
