A 15-segment display. Plug it in, open Config Portal, join WiFi, and tell it which trains and buses to follow.
The keys are not labeled. Down the left edge, from top to bottom:
One button sits on the right, level with the top-left button. That button changes what the board is showing. It does not open Config Portal.
A star (*) marks the selected line. Press the top-left button until the top row reads Root. The lines under it are Displays, Channels, Settings, Config Portal, System, and Controls.
Move the star to Config Portal and press the open button (the fourth button down the left edge).
That screen starts a local WiFi network named SEGMENT DISPLAY. It has no password. Stay on this screen while you use your phone. The up and down buttons scroll the short instructions on the board. This page is the full version.
The setup network is 2.4 GHz, and it has no internet. Look up API keys and stop IDs on your home WiFi before you join SEGMENT DISPLAY. Those pages will not load while the phone is on the setup network.
SEGMENT DISPLAY.Your home network has to be 2.4 GHz, or a dual-band network that still offers 2.4 GHz. The board cannot join a 5 GHz-only network.
Saving can knock the phone off SEGMENT DISPLAY. If the setup page disappears, join SEGMENT DISPLAY again and open http://192.168.4.1.
On the setup page, tap Commuter Board Configs. Fill in the stops you want, then tap Save. Blank rows are fine. You can come back later and change them.
Chicago (CTA) and Washington (WMATA) are separate blocks on that page. Use the one for your city. Each agency gives you a free key. The key is stored on the board.
A bus needs three things: a key, a route number, and a stop ID. You can track up to four stops.
Same page, under the heading DC / WMATA. One key covers rail and bus.
C04. Find them on the same developer site. Paste them into Rail 1 Station Code and, if you want a second station, Rail 2 Station Code.1001318, also on that developer site. Paste them into Bus 1 Stop ID through Bus 4 Stop ID under the DC / WMATA heading. Each of those fields takes a stop ID. Chicago route numbers go in the route fields above this heading.Press the top-left button. The setup network turns off, and the board joins the WiFi you saved.
To see Chicago arrivals, go back to the Root menu, open Displays, then open CTA.
Once it is online it can receive over-the-air firmware updates. Leave it plugged in. A board that is unplugged for a long time will pick up updates the next time it is online.
You can open Config Portal again any time to change the WiFi network or the stops.
Mail support@delimiterco.com with a description of what you see. Include the order number if you have it.
