USING THE PSC16 WITH WIEGAND
The PSC16 can be used with any standard wiegand and most non standard
wiegand controllers. The site (facility) code for the keypad can be set from the
keypad itself (refer to the Wiegand Keypad Options section) and the wiegand
data is fully configurable with up to 64 bits of data. The PSC16 also supports
controllers that require burst mode format wiegand.
To use the PSC16 in wiegand mode (non burst), press the code then
key.
The PSC16 can be set up to automatically send the code after a given number
of key presses by setting memory 007 (refer to the General Options section).
PSC16 TO WIEGAND WIRING DIAGRAM
Remember to press
after the code to send it, unless memory 007 has been
set to auto send after a given number of keys.
Use a positive signal (2.5 to 28V) from the controller on the Blue wire to change
the LED colour to blue.
Use a negative signal (0 to 2V) from the controller on the Yellow wire to change
the LED colour to blue.
Use a negative signal (0 to 2V) from the controller on the Brown wire to sound
the buzzer.
PSC16 OPTIONS
There are several options that can be set to alter the way in which the PSC16
behaves. These options fall into the 4 categories of General, Presco, Wiegand
Keypad and Wiegand Em
Card Proximity Reader, all of these are explained
below.
General Options
These options set the functionality of the PSC16 independent of whether it is in
wiegand or Presco mode.

(2) - Auto send key count
[Memory 007]
When this memory is set to a non zero value the PSC16 will automatically send
the data after

Note:
In Presco mode the auto send is disabled if the first key pressed is a
