THE APO DATA I/O PORT -- FOR SETTING UP A SPLIT-DECODED KEYPAD
The information here is for setting up the keypad unit with an optional “Digital Keypad Access
Controller DA-2800” to make up a high security Split-decoded Keypad system only. It is NOT
required for the keypad in Stand Alone operation.
The access control system utilizing of Wiegand data and control panel approach is usually taken by
consultants when setting their product designs. Most of the general end users do not make system
installation criteria by themselves but just like to up grade their system to a split-decoded system. A
Digital Keypad Access Controller DA-2800 is instantly available from APO for purchase. This keypad
is fully compatible with the DA-2800.
The keypad unit comes with a data I/O (data input and output) port for the connection with the APO’s
Access Controller DA-2800 for Split-decoded operation to up-grade its security level. Once the
keypad unit is connected with the controller, all the commands from it will be faithfully decoded by the
decoder. The input & output control functions available from the keypad are now all transferred to the
controller. The keypad’s role is just a card reader and/or a keyboard for code entry. The link up of the
two units is very simple. It is just one wire (The White Wire) for the I/O ports and a common grounding
wire (The Black Wire) for the two units. The I/O port provides the data in the proprietary APO format. It
ONLY works with the DA-2800.
The Optional DA-2800 Controller --- Introduction
The DA-2800 controller unit is compatible with the keypad unit. Maximum 3 keypads can be
connected in parallel to it. It decodes the data faithfully from the keypads even each of them have
different settings of their own. The only criterion for multi-keypad link-up is all the keypads are set with
the same Master Code and is read by the controller while it is in the link-up mode.
Apart from the decoding function to follow the features from the keypad(s), the DA-2800 is also
an independent 4-channel RF remote controller to operate its 3 output relays and the built-in door
chime. The DA-2800 is an ideal device working independently in the RF remote control areas, such
as door lock strike in access control, garage door opening control, alarm arm-disarming control and
automatic operator control etc.
The keypad unit is up graded to a Tri-Tech system after in connection with the DA-2800 controller. The
system accepts EM Cards, User PINs and the RF Remote Keys in access control.
The User Manual of the DA-2800 provides the operation details of the system on decoding controller
mode and independent operation mode.
Please contact your local agent if purchase of the DA-2800 Controller is required.
