Just purchased Ted TX 400(2) and one RX.
Ran it in parrell with wired system and it captured every impulse to the .001 All day.
Not line of sight and over 900 meters in distance from start to RX. Also tested it at Gore, NY on SG trail from start to hole in finish. It got solid sound. Gore is through solid rock and radios need repeaters to reach top. Very impressed.

Welcome to the club and fans of the Teds. I have easily sent signals in excess of 1500 meters at Whiteface and Winterpark and am sure they would do more.

So to do a USSA scored event (Level 3) with TED still need 4 timers plus the one you use with the the TED????????????????????
Thought you could use Two + One with Ted???????
What is the story in the US of A???
For:
Scored USSA J1/2 races?
Non Scored J3/4/&5 races?
Thanks,
N

Someone correct me if I'm wrong, but if the Start and Finish are hard wired, you could use the TED's for intermediate and speed traps without adding all the redundant timers.

If you plan on doing starts or finishes with a TED, then you would indeed need all the redundancy of 4 timers.

First, I never said I was timing ski racing, I was timing mountian biking. Second, I was using 4 timers. Third, for all FIS and USSA Scored events you need two timers at the finish. Each time you eliminate a pair of wires, you need to add a synchronized timer at the start to basically back-up the missing wires and whatever method you would use to relay information from the start.

So I need for a scored USSA wireless event:
One timer at start printing TOD all day.
One at finish printing TOD all Day.
Timer hooked to TED.
Total 3 timers.
or 2 timers at start +
2 at finish +
Tinmer hooked to TED
Total of 5 timers
Which is it? Just trying to figure it out to be within the rules.

See this FIS timing Guide. Timing without wire is covered with nice diagrams.

2 Pairs of wires = two timers at the finish
1 Pair of wires = two timers at the finish, one timer at the start.
0 Pairs wire = two timers at the finish, two timers at the start.

The TED doesn't eliminate the need for a timer at the start, it only provides a way to get the data, or impulse from start to finish and is basically seen the same way as a computer, its a nice accessory, but completely un-needed to time within the rules.

You must still have manual timekeeping in place for all events.

Yes I saw the diagram requiring 5 timers for wireless and thought requirment had been droped to 3. Thank you! BTW Timing MFG's love those rules.

I am not sure where you are getting 3 or 5 timers. Timing without wire requires 4 homologated timers. No more, not less required.

Jenna,
I still want TED connected to timer and SST computer to provide unofficial results that will be confirmed by 4 timers at S/F later. 4 +1= 5. If I could only use one timer at S/F I would still need one hooked to TED for unofficial results. 1+1+1=3. That is where I came up with 3/5 timers. Belive that once TOD's from S/F timers are confirmed with TED's Timer then you can make the results official. Downloading Start timers TOD's into Finish timers to use for verifification will take time after the race and not allow for timily awards. How would you set it up and produce results for scored wireless event?

No, this is NOT right.

2 + 2 = 4 No other configuration works.

The Ted isn't a timer.

It is perfectly acceptable to do OFFICIAL results off of impulses transmitted from start wand into System A timer at finish OR transmit TOD Data from Start timer A at start to finish timer A at finish.

This is how I would set this up.

System A:
Connect System A Timer at Start (timer 1) into System A inputs of start gate.
Connect System B Timer at Start (timer 2) into System B inputs of start gate.
Connect TED Transmitter into System A inputs of start gate to impulse (Black and Green) inputs of TED.
Connect System A timer at Finish (timer 3) into System A Photocell
Connect System B timer at finish (timer 4) into System B Photocell
Connect TED Receiver black and green into System A Timer at Finish (Timer 3).

Synch ALL Timers through TED using patch cord in finish building.

Execute the event using All Timers running in TOD mode.

Timer 3 is connected to computer generating results, providing scoreboard output, etc.

At end of race calculate ALL times for all racers using subtraction and comparison of Timer 1 and and Timer 3 and Timer 2 and Timer 4. Times don't have to be exact, but MUST be close and consistent. If everything looks accurate, consistent and without anomaly, all times as transmitted from impulses at the start to Timer 3 would stand.

TDRF Must be completed twice, once for timers at the start, once for timers at the finish. TDRF 1: Net times for System A (timer 3) at the finish comes from the impulses received to generate the System A (timer 3) start TOD. Net times for System B (timer 4) at the finish would be blank.
TDRF 2: Insert at TOD as appropriate from correct (A or B) timers. All net times come from using subtraction from Timer 1 and Timer 3 and Timer 2 and Timer 4).

Where do you get 5 timers?

So if my finish timers are in shoe boxes at the finish line running on batteries. I expect to use a timer hooked to TED in the timing building. Your asssuming I can run wire from finish to timing building.

I think that almost everybody here is assuming that, and Jenna provided a good explanation.

It seems you would like to get help for a VERY special configuration. In order to avoid wasting time, it would be easier if you provide a complete diagram of what you want to do.

I saw special situations with timing hut at the start, but the connections were by wire.

Remember that anything out of the FIS rules eventualy leads to a non homologated event.
If I were in your situation, I would ask to FIS's Cattaneo a written statement.
It's even likely that you may not get one, since you can't simply put together your HW in a FIS-accepted diagram.

I am not assuming wire from the finish to the timing buildings, the rules for both FIS and USSA REQUIRE wire from the finish photocells to the finish timers

Whether they are in boxes with batteries outside at the finish line, or 1000m away in a timing building, the FIS (and USSA) requirement is for wired connection of the finish. No other configuration is acceptable for a race on the FIS or USSA Calendar.

You can have a connection to the start without wire, but not the finish.

Jenna,
Thank you. Must have hard wires at finish. That clears up that issue. Now how do I deal with the .1 delay from the Ted Tx at the start, since I won't be balancing it with the TX .1 adder at the finish?

This also clears up running a compleatly wireless event for a scored USSA event, IT CAN'T BE DONE! Still hooked to a wire in NY.

Upon further review of FIS Wireless Precisions.
"ANY Timing Solution after 2 Homologated timers with printers are place at top and 2 are placed at finish is accetable."
Free at last. Free at last. Dear God almighty I am free at last.
This is where the 5th timer comes into play in my heated timing room at bottom of the hill hooked to the TED. While my regular finish line is not in use due to lack of snow.

You are mis-interpreting something written in a way that is not in the rules. Please see the diagrams. The finish timers must ALWAYS be hooked, by wire to the finish. The two timers at finish you refer to in that sentence are connected directly to the finish.

The "Any" refers to any method to send start times from the start to the finish as in a skier skiing down start time, a radio sending down start TODs, a wireless transmission device such as a TED sending impulses OR data, or "Any" other way you can think of. This does not mean you can add a timer, as this timer would not be part of your system A or System B. If you are taking times from a 5th timer that then become official, that would be system A and it would need to be connected as per the rules via a wire to the finish photocell A.

You seem to not like my answers regarding ski racing and "Timing without Wire". I am providing this input as a timing professional, FIS TD and the Vice Chair of USSA's Timing Working Group. If you don't like my answer, please feel free to contact either of the North American representatives to the FIS Timing Working Group, Ted Savage or Allen Church.

You can always choose to time any race, any way you wish, I certainly can't stop you, or actually do anything about it. I can only educate you on the proper way, and recommend to the USSA Classification Committee to not score a race that was not properly timed. I have no doubt the TD at a FIS race would ensure timing is completed as prescribed by the FIS rules, but the same could be done with scoring of the race and the FIS Classification Committee. This may never be an issue, but it would be a shame for all of the athletes entered if there were a problem or dispute over timing and the race not to get scored.

OK, Jenna is right with the layout of the 2 timers at the start and 2 timers at the finish. By hooking the TED to system A and to the "Start" channel at the finish (system A) using the TED is one way of this to work.

Now if you have another set of TED's you may then connect the RS232 output of the system A timer at the finish to send data to you in the race shack in which the Ted RX will be connected to your serial port of your computer.

This would allow you to "time" the race all from system A and if you "sync" through the TED system for the finish system "A", your .1 delay will not be a factor.

We time with a simplified method locally to allow the "timer..read computer" to be located in the bar and not in the race shack (better view of the race hill than the race shack). The race shack has an S4 with a TED-TX hooked directly to the RS232 output. (data mode).

You will still need 4 timers to pull this off properly.

The second rs232 TED system MUST be on a different freq. so not to interfere with the impulse TED's.

Sure, this works. I actually connect wirelessly to my timers as regular practice. Sending serial data from a timer connected to the photocells via wire is still different than sending wireless data from a photocell at the finish.

Instead his TED, Jim could also use use his MOXA Serial Device Server (SDS) or I could use my Quatech version and connect the SDS to a router with wireles signal. Then you can either connect to the router via LAN from wherever the timer is to wherever the the wireless LAN reaches. If the wireless LAN by itself doesn't have the range you need, add a cantena as John Jett does and get similar range as you would from our TEDs. Better yet open the UDP ports to the internet and use a WAN to connect to a virtual com port through the iternet. My router happens to allow WAN connection through a cell card (USB or Smart Card) so conceivably, I could send the system A data from a timer at any "finish line" with cell service to anywhere in the world. I believe this is the thinking behind the GSM dock that Tag Heuer built for the 540.

I digress, because you still have to have System A and B connected via wire to the finish...at most ski areas, its easier to buy a box of Cat 3 from HD Supply for $75 and run the 1000ft to the finish, or better yet, just time on a trail with wire?
