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.

(1) - Force Presco or wiegand mode [Memory 005]
101 = Always in Presco mode.
202 = Always in wiegand mode.
All other values = Mode auto detected using white wire.
(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 xkeys have been pressed, where x=value set for this memory.
Note: In Presco mode the auto send is disabled if the first key pressed is a 
or .

(3) - LED brightness factor [Memories 200 & 201]
The red & blue LEDs can have their brightness individually set
1 = LEDs are at lowest brightness.
20 =LEDs are at full brightness.
Presco Options
These options set how the PSC16 operates when in Presco mode. It is unlikely
that these options will need to be changed.

(4) - Internal/External mode Presco keypad [Memory 010]
101 = Internal mode keypad.
All other values = External mode keypad.
Note: When set to internal mode the two button Emergency () and One
Way Arm () features are enabled when used with a KC2 or KC6. This
setting has no effect when the unit is being used with any other Presco decoder
(e.g. PAC1 or PAC2).
(5) - Process received DTA characters [Memory 011]
101 = Ignore all received DTA characters (PSC16 will not give beeps, warble, etc.
after final is pressed).
All other values = PSC16 will make beeps, warble, etc. for DTA characters
received after pressing the final key.
(6) - Presco proximity reader output format (standard PAC format or KC
compatible) [Memory 012]
101 = Presco output from the prox reader is 7 digit KC compatible as per a PIM
wiegand to Presco conversion (only works for 26 bit wiegand cards).
202 = Presco output from the prox reader is 7 digit KC compatible using the
lowest 7 digits of the 9 digit Presco PAC code.
All other values = Presco output from RFID is standard 9 digit PAC format.
Wiegand Keypad Options
These options set the format of the wiegand data sent by the keypad when
wiegand mode is selected. The keypad can send up to 64 bits of data including
a site code up to 32 bits.

(7) - Number of bits for parity calculation [Memories 026, 027, 064 & 065]
Number of bits for parity calculation (0 = no parity bit, if the value is greater than
the total number of wiegand data bits (site code + user code bits) then it will use
half the total number of bits, for an odd number of bits the end parity will use 1
more bit).
(8) - Parity polarity [Memories 028 & 066]
0 = Start parity is Even, End parity is Even.
1 = Start parity is Odd, End parity is Even.
2 = Start parity is Even, End parity is Odd (default value).
3 = Start parity is Odd, End parity is Odd.
(9) - Error handling [Memory 029]
This memory specifies what information is sent via the wiegand interface when
a code entered is too large to be represented by the current wiegand format.
E.g. Standard 26 bit wiegand has a 16 bit user code which allows a maximum
code number of 65535. This memory determines what happens when a number
greater than 65535 is entered.
101 = A code of 0 is sent.
202 = No information is sent, the keypad ignores the input.
All other values = The maximum allowable code number for the current format
is sent (for 26 bit wiegand this is 65535).
(10) - Wiegand burst mode [Memory 032]
101 = 4 bit burst mode, , & keys data enabled (= ).
121 = 4 bit burst mode, , & keys data disabled.
202 = 8 bit burst mode, , & keys data enabled (= ).
212 = 8 bit burst mode, , & keys data disabled.
All other values = Standard, non burst mode wiegand.
(11) - Custom wiegand total number of bits [Memory 033]
When this memory is set to a value from 8 to 64 it overrides the standard wiegand
format of start parity followed by site code then user code then end parity and
replaces it with a fully customisable format with a total number of bits (including
any parity bits) as specified in this memory.
Note that using this option requires a high understanding of wiegand data. Nidac
will only offer limited support for this feature.
(12) - Send LSB first [Memory 034]
101 = LSB of data is sent first for both site and user code.
All other values = MSB of site and user code data sent first.
(13) - Default pattern bytes [Memories 040 to 047]
When the custom wiegand format is used by setting memory 033 then the data
in these memories is used to define the value for those bits not in use by the site
code, user code and parity bits. The data used starts from Bit 0 (LSB) in Default
Pattern byte 0 (memory 047), e.g. if the total number of bits is set to 24 then
Default Pattern bytes 2, 1 & 0 are used.
Wiegand EmCard Proximity Reader Options
These options set the format of the wiegand data sent by the PSC16 when it is
in wiegand mode and an EmRFID card or tag is being read.

(14) - 26 bit wiegand Emcard site code byte to use [Memory 060]
101 = Use alternate site code byte 1 from Emcard.
202 = Use alternate site code byte 2 from Emcard.
All other values = Standard Presco reader site code byte used.
(15) - Emcard custom wiegand format [Memory 061]
101 = 34 bit wiegand (16 bit site code, 16 bit user code, even start & odd end
parity bits for 16 data bits each) using Presco data.
121 = 34 bit wiegand as above using alternate site code data bytes.
202 = Custom wiegand format as defined by memories 62 to 68.
All other values = Standard 26 bit wiegand`.
(16) - Number of bits in Emcard site/ user code [Memories 062 & 063]
A maximum of 40 data bits can be set as a sum of these 2 memories. If the sum
exceeds 40 then the number of site code bits will be automatically reduced.
(17) - Data start bit from Emcard [Memories 067 & 068]
There are 40 bits of data in an Emcard organised as D00-D03, D10-D13, D20-
D23, D30-D33, D40-D43, D50-D53, D60-D63, D70-D73, D80-D83 and D90-D93.
Bit D00 is referred to as bit 1 for this memory and bit D93 as bit 40.
Be careful when setting the start bit to ensure that there are enough bits after the
start bit for the number of bits set for the site or user code data.
SETTING THE OPTIONS VIA THE PSC16 KEYPAD
To set any of the above options the PSC16 first needs to be placed into option
setting mode, this is done by following the steps below:
1. Remove power from the PSC16.
2. Connect the Orange wire to 0V or hold down the key.
3. Reapply power.
4. Once the LED starts to double flash blue you are in option setting mode.
5. Disconnect the Orange wire or release the key.
6. The PSC16 will remain in option setting mode for 5 minutes from the last
attempted option setting sequence.
Setting an option memory value
<3 digit memory number> <1 to 3 digit value> .
Reset all option memories to factory defaults
 whilst in option setting mode.
Exit Option Setting Mode
 or wait 5 minutes after last option setting attempt.
NOTE: Remember to disconnect the orange wire from 0V afterwards so that
should power go off the PSC16 will not start up in option setting mode when the
power is restored.
