Hi,

What's the best way to setup multiple timys with just a single tape switch?

I'd like to run a backup timy for a bike race, but only have a single set of contacts on the track in use.

Is it ok to connect a single tape switch to the input channels on both timy units? Or do you need to use a switch replicator/buffer?

Any info greatly appreciated.

You can parallel the tapeswitch into both TIMYs without a problem. The tapeswitch is normally open and there is no voltage involved.

Of course failure of the one switch will cause both TIMYs to have a bad channel that will have to be corrected.

Are you using an ALGE TSW1 tapeswitch control box between the switches and the TIMY?

The proper way to do it would be to use an optocoupler like The Blinky Box or a TAG Heuer HL 553 to split the tape switch signal 1:2.

Yes, we have a TSW1 control box, but it's getting very tired. I'll be replacing that with a splitter which connects C0-C5 instead of just C0,C2,C3.

I'm ok with the failed switch problem - for now.

Thanks!
