THE WIRE HARNESS FOR "WIEGAND DATA OUTPUT" & "Transmitter Solutions DATA I/O
NOTE: The information in this section is NOT for the system in Stand Alone operation. It is not necessary to plug in the
wire harness to the socket, just leave it open.
The information below is for setting the keypad unit with the Wiegand data interface to a control panel, or the
Transmitter Solutions Data I/O interface to an Transmitter Solutions Controller to make up a high security split-
decoded system.

Split-decoded Keypad System

Most of the general purpose keypads on the market are self-contained systems for stand alone operation. It controls
the appliance(s) directly with its output relay contact(s); such as the electric lock in an access control system. The
electric lock is connected to the keypad that is installed outside the house. The thief can open the door without a code
or card but just open the keypad box and make contact to the output relay terminal. It is a safety drawback in security.
The high security systems are usually operating in the Split-decoded mode that combines an outside unit for card
reading and code entry; and a control panel or a decoder unit installing in a secure closet inside the house. The
outside unit and the inside unit communicate in digital data with each other. All the commands are in digital
codes, the thief can do nothing to the inside unit even the outside unit is opened in sabotage. This design
philosophy confirms high security to the area protected, but not just relying on the protection of the keypad with the
outer box and two screws.

The Wire Harness

The keypad unit comes with two sets of interface wires from the wire harness. The Wires 1-4 are the Wiegand
interface wires. The Wire 6 is the Data Input/Output wire for the connection with the optional Transmitter Solutions's
Digital Keypad Access Controller, for high security Split-decoded operation. The Wire 5 is the Common
Grounding point of these signal wires. Please see the location of the wire Harness on Page 7.
