12 Reconfiguring the function
Although the PP500 can be user configured for different type of interfaces and pro-
tocols, it has the capabilities to be re-configured for different purposes. The follow-
ing chapters describe a range of parameters which can be altered.
12.1 Default configuration
You must set the following functions on a Reader before it will operate correctly:
– Distributor Code
– Secondary Code
You will probably need to set the following:
– Data interface option
You may need to set the following:
– Horn operation
– Internal/external/single-wire control of LEDs
– Hold-off time and repeat data delay
– Leading parity calculation for Wiegand data output
– Position of Secondary Code in data output
– Secondary Code check disable
– Data Hold input signal polarity
12.2 Configuring the Reader
You configure the Reader by presenting it with two coded cards. The first card
(the configuration card) defines the type of data interface, and all the features listed
in the third group above. The second card (any of the ordinary Distributor Coded
cards which will be used with the system) teaches the Reader its Distributor and
Secondary Codes. Note that you cannot teach the Reader its Distributor and Sec-
ondary Codes without first presenting the configuration card.
When the Reader is powered up, it waits 4 seconds for a configuration card to be
presented. If it doesn’t read a configuration card in this time, it enters its configured
operating mode.
