To fully utilize SRM on a Windows machine, you can install a boot selector with a second partition that contains MS-DOS and SRM. When you switch on your computer, you can select Windows or MS-DOS to boot.

Often I get the question if SRM supports external call buttons. Well ofcourse it does! SRM supports call buttons, external and internal. You can use the spacebar as a call button, but you can also connect external call buttons.

Most people use SRM to store fastest laps and ofcourse SRM does that in a great way: not only for you and your friends, but also for your cars. What a lot of you might not know is that SRM can also store fastest times for a preset amount of laps!

This error usually occurs when calling the Timing Core program (when starting to time your races). Read More...

-> Look under: "SRM does not run after copying it off a CD-ROM/CD-RW"

DOS error 4 means the operating system will not allow more open files, while SRM wants to open another file. Read More...

DOS error 2 means the program can't find the file specified. Read More...

Most timing software uses particular pins on the parallel port to read the sensors from. These pins are 10, 11, 12, 13 and 15 and they are on the so-called BASE+1 address (= parallel port addres + 1). With this setup, you can read 5 sensors on 1 parallel port.

Try out the PARPORT.EXE program first. You can download it from this website. Read More...

I'm afraid this is no error. The timing routine in SRM has no sound when timing a race or practise session. Read More...

This problem is caused by older hardware of the computer. To achieve real 0,001 second accuracy, SRM speeds up the pc's internal clock up to 600x the original speed during a timed race. Read More...

Because the timing software in SRM uses a clock speedup routine, it can happen that your computer clock (time/date) will slowly start to differ from the real time or date.

SRM uses a speed up of the internal clock to achieve real 0,001 second accurary. It makes the internal clock of the PC run up to 600 times faster. Only true MS-DOS allows this, Windows does not. Read More...

-> Your DIGITS.INI file is damaged or has the wrong format, reinstall it from the ZIP-file.
-> You have selected 'black' as your lane color, change this in your Track screen.

After you have copied the files from a CD-ROM/CD-RW, they will often stay read-only. They will keep this status after they are copied from CD.
-> For all files, switch off the read-only mode. Do this with the ATTRIB command:
ATTRIB -R *.*

Sometimes, SRM can miss a car when passing a timing sensor. This can have numerous reasons, but most of the time a hardware error is the cause. In general, there are a few things you need to pay attention to when you are going to place your sensors. Click on this topic to read the full info.
