Reference Drawing:
Insert, LL-2551 Price/T&T Display .............................. Drawing A-164999
The DataMaster 100 uses a keypad insert to program rate information into
Daktronics LED DataMaster Rate Displays.
Figure 10 illustrates the DM 100 insert used to control the displays. For details refer
to Drawing A-164999.
If an insert is lost or damaged, a copy of the insert drawing located in Appendix A
can be used until a replacement is ordered.
To start the controller and use the insert, read the next section carefully to fully
understand the operation instructions.
5.5 Rate Display Operation
The DataMaster 100 controller can be configured to program price variances
displayed on the LED DataMaster Rate sign. The instructions provided in this
section discuss the functions the operator uses to control the Rate display. In the
unlikely event that the Rate Display malfunctions, refer to Appendix B for the
Frequently Asked Questions section for this display.
Connect the display with the DataMaster. Often
when using either a modem or radio an output j-
box will also be connected for use if the other
means of communication fails.
Note: There is more than one way to get certain
LCD screens on the DM 100. One way is by
using the menu and then the arrows to reach
the desired programming location. The other
way is to set the first petroleum price and
then continue to enter through the additional
screens.
