The LNL-CK Lenel Command Keypad integrates a 32-character backlit LCD display with a 16-position keypad and a reader port. The command keypad serves as a command reader, a reader from which user commands can be issued to execute local I/O functions. Reader command programming is accomplished using the OnGuard System Administration application. The LNL-CK display indicates time in either 12 or 24-hour clock format. The format is automatically chosen based on the regional settings of the computer on which the Communication Server is running. The LNL-CK display also provides command status and other text feedback during reader operations. For example, when performing the Extended Held Open command, the LNL-CK displays the countdown time before the Held Open time is reached, as well as basic intrusion arm/disarm functions. The LNL-CK communicates with the Lenel Intelligent System Controller ISC either through direct, multidrop, 2-wire RS-485 communication to the ISC, or through a reader port of a Lenel Dual Reader Interface Module LNL-1320. The LNL-CK may be configured in one of three ways: as a stand-alone RS-485 device, as an alternate reader to a primary reader, or as a reader device connected to the Wiegand input of a LNL-1320. In any of these modes, an optional reader with a Data1/Data0 or clock/data output may be connected to the LNL-CK to provide Card Only, Card or PIN, or Card and PIN capability.
