The FD-KA01 is part of the OrangeLink and is suitable to enter numeric or alphabetic keys for: ♦ the PIN code (Personal Identification Number) ♦ entering "reasons" associated to the Time & Attendance clock-in/out. ♦ Asking information on Time & Attendance balances (enquiries) The FD-KA01 has also following characteristics: ♦ Visual indications through 4 multicolored LEDs (red/green/yellow) behind the function keys (F1..F4, "C" and "E"nter). The green or red light ♦ Audible signal through an internal buzzer ♦ Connection to the FD-BUS using SPP (Serial Proprietary Protocol) at a speed of 115.2 Kbaud (default) or 19.2 ♦ Address selection for the reader by means of a rotary switch on the back of the device ♦ Double connector (internally in parallel) for easy reconnection to the FD-BUS. The equipment is protected against the following events: ♦ polarity reversal on the cables (RJ45) connecting to the FD-BUS ♦ voltage surge in the power supply ♦ negative voltage peaks at outputs with inductive loads Connected to the Field Manager or to the XPoint, the FD-KA01 can be used to have a more secure Access Control allowing the PIN code and the duress code to be entered together other identification media. In a Tiem & Attendance application the FD-KA01 can also be used to add information to the time record entering reasons or to get information on balances or the buffered clock-in/out._
