Theory of operation

This new setting is found on the Device Setup tab under the button LED Drive Current:

This is used to change the drive current setting for the LED display boards. The current standard is 10 mA. The 20 mA setting is only used if you have installed the replacement controller above into an older system from 2010 or older. These systems utilized LED display boards that were less efficient and require a higher current setting to be at an equivalent brightness to the current revision display boards. Reference our controller replacement guide for more information on adjusting this setting.
