I'm a broadcast graphics supplier and I need to implement timing for a sportscompetition which will be broadcasted on tv, but I'm facing some issues and I hope I can find some answers here.
I was able to loan a CP540 and some photocells and transmitters and receivers.
I have everything hooked up together and when I physically test the photocells, they are working. When I interrupt the beam of the photocells, the signal is sent up to the reciever. So that's all working fine.
On the CP540-side I am able to connect to the ChronoPrinter and I receive data when I use the manual test-buttons 1 -> 4. However, it seems I am not getting any data from the receiver.
I have two photocells, one for start and one for finish, which are arriving at port 1 and 2 on the Receiver-side.
I have read the manual of the CP540 and I saw that I have to connect start and finish on port 1 and 4 because ports 2 and 3 are used for intermediate timing.
So I have connected Port 1 and 2 of the receiver to Port 1 and 4 of the CP540, but this is not triggering the CP540. Does anybody know what I'm doing wrong?
I have attached a picture of the cabling between the receiver and the CP540.
I also have a second, related question. I was thinking that my issue might have to do something with the Timing Mode and with the fact if i'm in a Run or not.
Now, for my use, I don't use the CP540 for actual timing or ranking. I only use it's time of day. So the information I'm interested in, is when the start-cell was interrupted and when the subsequent finish-cell was interrupted. Which is essentially the information I get when I use the 1 > 4 testbuttons.
So in my software I select the competitor and then when the start-cell is interrupted, I add the received time from the CP540 in my database. When the competitor passes the finishline I repeat the same thing. I activate the competitor and the received time of the CP540 will be added to my database and the difference will be calculated.
Does anybody know which Timingmode I have to use for this?
A third (and last) question; The CP540 is supposed to be a very accurate timing device. Is there any way that I can sync my pc-clock to the internal timing of the CP540 so I can use it as a sort of Master Clock?
