EL2300 can operate in PIN mode, CARD mode, or CARD+PIN mode.
In CARD+PIN mode, the PIN can be generated by an internal algorithm, or set by the user. A card can be de-registered if wrong PIN is repeatedly entered.
All modes of operation are subjected to time zone constraints. 10 time zones are provided, and each time zone has an 8-day schedule (7 weekdays + 1 holiday) with 2 start/stop periods per day.
Doors can be programmed to be unlocked automatically by timers. Changing from CARD to CARD+PIN mode can also be automatically activated by timers.
Up to 20 holidays can pre-programmed into the controller, and a separate access routine set for holidays

EL2300 is designed to work with a wide choice of signals from various types of standard readers. This include F2F signals (magnetic readers), raw optical signals (bar code readers), and Wiegand signals (proximity and smart card readers). For each type of reader, users can select different formats.For example, for Wiegand signals, 4 different formats can be selected:-26-bit standard format,HID Corporate 2000 format,ELIDformat,user-define format                                                                                      For bar code, 2 formats can be selected: 2 of 5 interleaved, and 3 of 9                                  For magnetic, 2 formats can be selected: ELID and ABA.                                                                                                                                         

EL2300 is designed to work specifically with ELID’s serial readers which are equipped with 7-segment or LCD display and keypad. The display is to improve feedback to users.
For example, if the controller is waiting for PIN to be entered, the display will show “PIN”. If a card is rejected, because of wrong time zone, the display will show E-CA (Error in Category). If a card is rejected because of antipassback,
it will show E-AP. LCD version of the keypad/reader EK8G will display English or Chinese text in full.

Depending on the model and set-up selections, EL2300 can store up to 25,000 user ID card numbers.For secure applications, cards can be assigned to 2 separate groups, and access is only granted when 2 cards from different groups are successively swiped. Apart from normal user ID cards, it also distinguishes Special Cards, which can perform alarm arming/disarming functions, and activation/deactivation of outputs. EL2300 recognizes 22 different types of activities (such as “valid entry, ‘door forced open’, ‘wrong PIN’ etc). It records each transaction with date, time, and card number. Depending on setting, up to 10,000 transactions can be stored. These transactions can be retrieved by a PC or directly printed out to a serial printer.

EL2300 comes with 2 non-supervised inputs and 6 opencollector outputs. The inputs may be used for monitoring status or alarm signals. The outputs can be timer controlled or event controlled. In the timer mode, it is activated by an 8-day time zone. In the event-controlled mode, the user can select what event or combination of events to activate a specific output. Any of the 22 events recognized by EL2300 can be used to set the formula.

EL2300 is equipped with multi-drop, RS485 and LAN. For multi-drop and RS485 mode, up to 16 units can be connected together to form one bus. Address setting in each controller is then used to distinguish one controller from another. If LAN is used, the controller is distinguished by its IP address plus its unit address. This method of communication is used in most of ELID’s standard equipment, and so different models can continue to work together when connected to the same bus.
