7. Power up the DM-100 handheld controller.
Note: Do not press any buttons on the DM-100 while displays and controller are booting up.
8. Allow time for DM-100 to boot up and initialize all pylons.
a. About 1 minute for each wirelessly connected pylon
b. About 1 minute total for a direct-wired pylon system
9. On the DM-100, press Menu > Detect Displays to verify all networks and displays are detected.
10. Verify all displays and lines are detected.
11. Manually send the current prices to the display(s) from the DM-100.
12. Verify that the DM-100 states “Sequence Sent” then “Display Response”.
Use the following as a guide for some Point of Sales Systems, I.E. Radiant
1. Verify the ICON on the PoS register does not say, “Price sign is off-line”, if it does, connect the PoS to
the DM-100.
2. Manually send the current prices to the display(s) from the DM-100. (Override the PoS)
3. Press the Update Display button on the DM-100.
4. Verify DM-100 states “Sending Sequence” then “Display Response”.
5. Re-send current prices from PoS system.
6. Verify price change with PoS.
7. The price on the display should change within a minute.
Note: Some states only allow one price change per day. The procedure above allows system
verification without actually changing the display’s price. If allowed, test the entire system by
sending a penny increase to one of the displays and verify change. Return to correct price.
Note: To retain price updates, you must wait 3 minutes before powering down the gas price displays. Any
changes made to the displays require a 3-minute power on time to commit to memory.
