1 Description<br />
The Timer S is used in conjunction with the computer-aided<br />
measuring system CASSY ® . It gives access to the timer inputs<br />
of CASSY as inputs E and F for the transfer of the measuring<br />
signal and for the voltage supply of the connected sensor.<br />
Experiment examples are found on the CD of the CASSY Lab<br />
software (<strong>524</strong> 200) or in the download version of the software<br />
under http://www.ld-didactic.com or in the manual of the<br />
CASSY Lab software (<strong>524</strong> 201).<br />
2 Sensors to be used<br />

–––<br />
Being a member of the CASSY family, the Timer S has the<br />
following properties:<br />
• The Timer S may be plugged in at any time.<br />
• The plugged-in Timer S will be automatically identified.<br />
• Measurement quantities and measuring ranges are set via<br />
menus.<br />
7 Updates<br />
If the software or firmware used is older than that given above,<br />
an update of the software or firmware is required. The current<br />
version of the CASSY Lab software is available on the internet<br />
under http://www.ld-didactic.com.<br />
- Install the current version of the CASSY Lab software and<br />
start it.<br />
- Connect all available CASSY modules to the PC one after<br />
another.<br />
- As soon as you are prompted, bring the firmware up to date<br />
with “Update CASSY Modules” so that it matches with<br />
