At a FIS race last weekend, we were using the Tag HL2-32 through beams with the sync cable. After a flawless first run, we stopped getting finishes on our primary setup. In between runs, we swaped the wires (black to green, green to black) going into the primary photocell and then received finishes. We finished the rest of the race with the reversed wiring. Any ideas on why the polarity would switch in the middle of a race like that? We fixed it for the time being, but would like to get to the root of the problem ASAP. Any input would be appreciated. Thanks.
