Design Mode & Custom LED Modes
1.0 Introduction
When using Mercury and NXT Mercury-Powered controllers there are three available default LED modes defined in the software that control how the reader’s LEDs behave when the various modes are set to the readers. Examples of these modes are; Unlocked, Lockdown, Lockout, PIN only, Card + PIN, Access Denied, Access Granted, Locked, etc. By default, all readers connected to Mercury and NXT Mercury-Powered controllers are set to use LED Mode 1. You can use the Design Mode feature to edit any one of the default LED modes.
