The Summit Bridge is no longer supported. Use the Summit App instead.
What changed
The Summit Bridge was the page on zone4.ca (Timing Devices → … → Experimental Summit Bridge) that connected to the Summit radio modem through the Chrome browser. Zone4 no longer supports collecting Summit times through a web browser.
Browsers aren't a reliable tool for connecting long-running serial devices: they slow down or pause pages that are in the background or minimised, and they can drop the connection to the modem, so times can stop arriving without any warning.
The Summit App is a desktop app that does the same job without those limits. It also:
- keeps collecting when its window is hidden or minimised;
- reconnects on its own if the modem is unplugged;
- syncs the Summit clocks to within a few milliseconds;
- doesn't send your times again after a clock re-sync.
Switching to the Summit App
- Close any Summit Bridge tabs. Only one program can use the modem at a time.
- Download the Summit App and open it.
- Follow Getting set up: log in to your club once, choose the modem's port, start communication and sync the Summit clocks.
Your Summits, radio modem and modem driver stay the same, and times go to your races on Zone4 as before. If the computer doesn't find the modem, see Installing the modem's driver.
For races with no internet at all, a Serverbox remains the most robust option.
