Converting from Prove Keypads & Readers
The PIM can read information from any of the Prove keypads and
proximity readers as well as older Presco keypads and readers.
Note that no information is sent from a Prove keypad until the E
key is pressed (use #on keypads that don’t have an Ekey).
It can then convert the information to Wiegand, Clock & Data,
USB or RS232.
Prove keypad or reader to Wiegand
Switch 5 ON
The Presco data can be converted to either standard Wiegand or
burst mode Wiegand. There are several settings for both these
modes that can be set, please refer to the WIEGAND TRANSMIT
SETTINGS MEMORIES section.
In standard mode the code entered from the keypad will become
the user code of the Wiegand data and the site code will be taken
from memories 125 to 128.
When converting to standard 26 bit Wiegand from a Prove
proximity reader the PIM will produce the same site and user
codes as if the Wiegand output from the reader had been used.
This is useful if wanting to cable a Wiegand system further than
100m from reader to controller. If converting to a Wiegand format
other than standard 26 bit, the result is undefined.
The PIM automatically makes the Prove device respond with the
noise as set in memories 021 and 022 for good and bad inputs
respectively (a bad input is when a number too large to convert
to the user code is entered from a keypad).
Prove keypad or reader to Clock & Data
Switches 1 & 5 ON
The Presco data can be converted to 1 to 32 digits of track 1, 2
or 3 format Clock & Data. Please refer to the CLOCK & DATA
TRANSMIT SETTINGS MEMORIES section for these settings.
Prove keypad or reader to RS232
Switches 2 & 5 ON
Once the data has been entered at a Prove keypad or prox reader
(codethen Eor #pressedonkeypadorcardpresented at reader)
it will be sent to the RS232 port.
The PIM can then optionally make the encoder respond with a
noise as set by the good return character in memory 021, or the
return beep code can be sent back via the RS232 port within 3
seconds. The default settings are to make the encoder respond
with a single beep.
Data sent to the RS232 port can be either filtered (only the code
digits are sent) or unfiltered (preamble characters, code and
enter character are sent). The default setting is to filter the data.
Further settings are available for RS232 data. Please refer to the
RS232 SETTINGS MEMORIES section.
Prove keypad or reader to USB
Switches 1, 2 & 5 ON
Once the data has been entered at a Prove keypad or prox reader
(codethen Eor #pressedonkeypadorcardpresented at reader)
it will be sent to the USB port.
The PIM can then optionally make the encoder respond with a
noise as set by the good return character in memory 021, or the
return beep code can be sent back via the USB port within 3
seconds. The default settings are to make the encoder respond
with a single beep.
Data sent to the USB port can be either filtered (only the code
digits are sent) or unfiltered (preamble –characters, code and
enter character are sent). The default setting is to filter the data.
Please refer to the USB SETTINGS MEMORIES section.
Converting from Wiegand
The PIM can read up to 128 bits of Wiegand data with or without
start and/or end parity bits. It also allows for a site code of up to
32 bits. The default settings are for the PIM to read standard 26
bit Wiegand.
Wiegand to Presco for PAC1 or PAC2
Switch 2 ON
The PIM creates an 8 digit number from the Wiegand data.
When receiving 26 bit Wiegand it converts the site code to a 3
digit decimal number, then it converts the user code to a 5 digit
decimal number and combines these to create the 8 digit code.
e.g. Site Code = 083, User Code = 02845
PIM code = 08302845
this is the number to program into the PAC1 or 2.
Wiegand to Presco for PDA, KC2 or KC6
Switches 1 & 2 ON
The PIM creates a 7 digitnumber from the Wiegand data. When
receiving 26 bit Wiegand it converts the site code to a 3 digit
decimal number and takes the lowest 2 digits then it converts the
user code to a 5 digit decimal number and combines these to
create the 7 digit code.
e.g. Site Code = 183, User Code = 02845
PIM code = 8302845
this is the number to program into the PDA, KC2 or KC6.

3
Wiegand to Wiegand
Switch 2 ON
The PIM can be used to convert from one format of Wiegand to
another or, by setting memory 105 to0, it can be used to replace
the site of the received Wiegand and retransmit in the same
format (or another) but with the site code that is stored in the PIM
in memories 125 to 128.
Wiegand to Clock & Data
Switches 1 & 2 ON
The PIM creates code from the Wiegand data that consists of the
site code (converted to decimal) then the user code (converted
to decimal). It then combines these 2 together and transmits the
last n digits of the code, where n is the value set in memory 080.
When receiving 26 bit Wiegand it converts the site code to a 3
digit decimal number, then it converts the user code to a 5 digit
decimal number and combines these to create an 8 digit code.
e.g. Site Code = 183, User Code = 02845
Memory 080 = 8
Clock & Data code = 18302845
Optionally the site code portion can be discarded by setting
memory 105 to 0 so that the clock & data code in the example
above becomes 00002845.
If value set in memory 080 is more than the number of digits
created by the code conversion leading 0s will be sent to make
up the number.
Wiegand to USB or RS232
Switch
2 ON
or
Switches 1
& 2 ON
The data can be sent to the USB and RS232 port as either raw
binary data, ASCII encoded decimal or ASCII encoded
Hexadecimal (see memory 007). The site and user codes are
converted and sent as separate numbers with the site code being
sent first. The default setting is to send the data as ASCII
encoded decimal.
Further settings are available for USB & RS232 data. Please
refer to the USB and RS232 SETTINGS MEMORIES sections.
Converting from Clock & Data
When reading from a Clock& Data device thePIM accepts Track
1, 2 or 3 format Clock & Data inputs using just the RDP and RCP
signals.
The PIM reads up to a maximum of 32 characters from the data
stream, though the number of characters used is dependent
upon the data conversion type.
The PIM can read characters from several different locations
depending upon the settings of memories 062 & 063. The default
it setting is to read characters directly before the first separator
character (or end sentinel if no separator was found).
Clock & Data to Presco for PAC1 or PAC2
Switch 4 ON
The PIM reads up to nine (9) digits from the data stream.
If reading from track 1 and a non-numeric character is found in
the data stream then the PIM will ignore the card.
Clock & Data to Presco for PDA, KC2 or KC6
Switches 1 & 4 ON
The PIM reads up to seven (7) digits from the data stream.
If reading from track 1 and a non-numeric character is found in
the data stream then the PIM will ignore the card.
Clock & Data to Wiegand
Switch 4 ON
The PIM reads up to 32 characters from the data stream.
If reading from track 1 and a non-numeric character is found in
the data stream then the PIM will ignore the card.
The data read from the Clock & Data source is converted to a
binary number. The bits above the number of bits specified for
the Wiegand user code are then discarded.
Clock & Data to Clock & Data
Switches 1 & 4 ON
The PIM can be used to convert between Track 1 & Track 2 or 3
data format and can be used to manipulate the received data and
resend only the required part.
Clock & Data to USB or RS232
Switch
4 ON
or
Switches 1
& 4 ON
The PIM reads up to 32 characters from the data stream and
sends the data to the USB and RS232 ports as ASCII characters.
Further settings are available for USB & RS232 data. Please
refer to the USB and RS232 SETTINGS MEMORIES sections.
Converting from Dallas iButton
Either the unique factory ID code or the user memory (selected
iButtons only) can be read.
When reading the factory ID up to 64 bits canbe read, 8 bit CRC,
8 bit family code + 48 bit serial number.
Up to 128 bits of user memory can be read.
NOTE: The PIM will not read an iButton’s memory that contains
all 0s or all 1s for the number of bits being read.
The default setting is to read 32 bits from the factory ID.
Dallas iButton to Presco for PAC1 or PAC2
Switches 2 & 4 ON
The PIM reads the number of bits specified and converts them to
a either a decimal or base 12 number (refer to memory 044). The
lowest 9 digits of this number are sent as the code. The default
setting is to convert to base 12.
Dallas iButton to Presco for PDA, KC2 or KC6
Switches 1, 2 & 4 ON
The PIM reads the number of bits specified and converts them to
a decimal number. The lowest 7 digits of this number are sent
as the code.
Dallas iButton to Wiegand
Switches 2 & 4 ON
If the number of bits read from the iButton is less than the number
of bits specified for the Wiegand user code then the user code
will be padded with leading zeroes (0).
If the number of bits read from the iButton is more than the
number of bits specified for the Wiegand user code then only the
lower bits will be sent as the Wiegand user code.
Dallas iButton to Clock & Data
Switches 1, 2 & 4 ON
The PIM reads the number of bits specified and converts them to
a decimal number. The lowest n digits of this number are sent
as the clock & data code, where n is the value of memory 080.
Dallas iButton to USB or RS232
Switches
2 & 4 ON
or
Switches
1, 2 & 4 ON
The data can be sent to the USB and RS232 port as either raw
binary data, ASCII encoded decimal or ASCII encoded
Hexadecimal. The default setting is to send the data as ASCII
encoded decimal.
Further settings are available for USB & RS232 data. Please
refer to the USB and RS232 SETTINGS MEMORIES sections.
Converting from RS232
The PIM converts from RS232 to Wiegand, clock & data or Presco.
RS232 to Wiegand
Switches 3 & 4 ON
When the PIM is set to transmit standard format Wiegand the
data sent via the RS232 input needs to be formatted correctly.
First the PIM needs to receive the start character as specified in
memory 004 then the data to be converted to Wiegand (as a
decimal number represented by ASCII coded digits) followed by
the end character as specified in memory 005. If the data
contains a separator character as specified in memory 006 then
the digits after the start but before the separator will be converted
to the site code and the digits after the separator will be
converted to the user code. When no separator if sent all digits
will be converted to the user code and the sitecode stored in the
PIM will be sent.
When the PIM is set to transmitburst mode Wiegand the PIM will
convert each ASCII coded digit received on the RS232 and
transmit it as burst mode.
RS232 to Clock & Data
Switches 1, 3 & 4 ON
The data sent via the RS232 input needs to be formatted
correctly for the PIM to output Clock & Data. First the PIM needs
to receive the start character as specified in memory 004 then
the characters to be sent as clock & data followed by the end
character as specified in memory 005. If the data contains any
separator chars as specified in memory 006 then these will be
converted to the appropriate separator character for the track
type being transmitted and sent with the other characters. The
PIM will automatically transmit the correct start & end sentinels
for the track type being transmitted.
RS232 to Presco Controller
Switches 2, 3 & 4 ON
The data sent via the RS232 input needs to be formatted
correctly for the PIM to output Presco. First the PIM needs to
receive the start character as specified in memory 004 then the
characters to be sent as Presco followed by the end character as
specified in memory 005. The correct preamble and end
characters need to be included in the data.
Converting from USB
The PIM converts from USB to Wiegand, clock & data, Presco or
Presco DLOG.
USB to Wiegand
Switches 4 & 5 ON
When the PIM is set to transmit standard format Wiegand the
data sent via the USB input needs to be formatted correctly. First
the PIM needs to receive the start character as specified in
memory 004 then the data to be converted to Wiegand (as a
decimal number represented by ASCII coded digits) followed by
the end character as specified in memory 005. If the data
contains a separator character as specified in memory 006 then
the digits after the start but before the separator will be converted
to the site code and the digits after the separator will be
converted to the user code. When no separator if sent all digits
will be converted to the user code and the sitecode stored in the
PIM will be sent.
When the PIM is set to transmit burst mode Wiegand the output
is undefined.
USB to Clock & Data
Switches 1, 4 & 5 ON
The data sent via the USB input needs to be formatted correctly
for the PIM to output Clock &Data. First the PIM needs to receive
the start character as specified in memory 004 then the
characters to be sent as clock & data followed by the end
character as specified in memory 005. If the data contains any
separator chars as specified in memory 006 then these will be
converted to the appropriate separator character for the track
type being transmitted and sent with the other characters. The
PIM will automatically transmit the correct start & end sentinels
for the track type being transmitted.
USB to Presco Controller
Switches 2, 4 & 5 ON
The data sent via the USB input needs to be formatted correctly
for the PIM to output Presco. First the PIM needs to receive the
start character as specified in memory 004 then the characters
to be sent as Presco followed by the end character as specified
in memory 005. The correct preamble and end characters need
to be included in the data.

103 Number of bits for end parity (0 = no end parity bit, 128
or greater = use half the total number of data bits)
[255].
104 Parity polarity:
0 = Start & End Even,
1 = Start Odd & End Even,
2 = Start Even & End Odd,
3 = Start & End Odd,
4 = Do not check parity.
105 Transmit received site code: [255]
0 = Don’t transmit the received site code,
All other values = Do transmit.
Note that this memory has no effect when transmitting
USB or RS232 data.
110 Custom total number of receive bits [255].
When this memory is set to 0 the PIM will ignore all
settings in memories 100 to 105 and 111 to 113 and will
receive Wiegand data until either is has received 128
bits of data or 8 milliseconds has elapsed since it
received its last data bit. All these bits will be treated as
the user code with no site code data.
When this memory contains a value that specifies a
total number of data bits of between 8 & 128 then the
custom Wiegand receive mode is enabled (if start
and/or end parity is specified in memories 102 & 103
then these bits need to be taken into account when
specifying the total number of bits).
The number of bits for the site & user code are still as
specified in memories 100 & 101 but the starting
position of the site & user codes within the received bits
can be specified via memories 112 & 113.
Note that using this setting requires a high
understanding of Wiegand data. NIDAC will only offer
limited support for this feature.
111 Expect LSB first in custom mode: [255]
1 = LSB is received first when in custom mode,
All other values = MSB received first.
112 The bit number within the received data that the site
code data starts at (only used when in custom receive
mode), note that the first bit received is bit 1. [255]
113The bit number within the received data that the user
code data starts at (only used when in custom receive
mode), note that the first bit received is bit 1. [255]
WIEGAND TRANSMIT SETTINGS MEMORIES
The default memory settings are to transmit standard 26 bit
Wiegand.
120 Number of bits in site code: 0 to 32 [8].
121 Number of bits in user code: 8 to 128 [16].
122 Number of bits for start parity (0 = no start parity bit,
128 or greater = use half the total number of data bits)
[255].
123 Number of bits for end parity (0 = no end parity bit, 128
or greater = use half the total number of data bits)
[255].
124 Parity polarity:
0 = Start & End Even,
1 = Start Odd & End Even,
2 = Start Even & End Odd,
3 = Start & End Odd.
125 Site code byte 3 (bits 24 to 31): 0 to 255 [0].
126 Site code byte 2 (bits 16 to 23): 0 to 255 [0].
127 Site code byte 1 (bits 8 to 15): 0 to 255 [0].
128 Site code byte 0 (bits 0 to 7): 0 to 255 [1] (used for
standard 8 bit site code, when using 26 bit Wiegand).
130 Wiegand transmit mode:
0 = standard,
1 = 4 bit burst mode,
2 = 4 bit burst mode ignoring *and #keys,
3 = 8 bit burst mode,
4 = 8 bit burst mode ignoring *and #keys,
5 = 4 bit burst mode and a #at end of code,
6 = 8 bit burst mode and a #at end of code.
In 4 or 8 bit burst mode each digit received is sent as an
individual Wiegand burst character at a rate determined
by memory 131.
Note that when using a Prove keypad no data is sent
until the Ekey is pressed (#key on a VR43, VR62 or
PSE).
Note: setting options 5 & 6 are only valid when
converting from Presco and are only available with
firmware revision 3d or greater.
131 Burst Mode Delay, the delay between sending burst
mode characters in 0.1 second increments. [2]
132 Custom total number of transmit bits [255].
When this memory contains a value that specifies a
total number of data bits of between 8 & 128 then the
custom Wiegand transmit mode is enabled (if start
and/or end parity is specified in memories 122 & 123
then these bits need to be taken into account when
specifying the total number of bits).
The number of bits for the site & user code are still as
specified in memories 120 & 121 but the starting
position of the site & user codes within the transmitted
bits can be specified via memories 134 & 135.
Note that using this setting requires a high
understanding of Wiegand data. NIDAC will only offer
limited support for this feature.
133 Send LSB first in custom mode: [255]
1 = LSB is transmitted first when in custom mode,
All other values = MSB received first.
134 The bit number within the transmitted data that the site
code data starts at (only used when in custom transmit
mode), note that the first bit transmitted is bit 1. [255]
135 The bit number within the transmitted data that the user
code data starts at (only used when in custom transmit
mode), note that the first bit transmitted is bit 1. [255]
140 Default custom Wiegand pattern byte 15.[255]
141 Default custom Wiegand pattern byte 14.[255]
142 Default custom Wiegand pattern byte 13.[255]

|
153 Default custom Wiegand pattern byte 2. [255]
154 Default custom Wiegand pattern byte 1. [255]
155 Default custom Wiegand pattern byte 0. [255]
Memories 140 to 155 specify the default pattern to be used when
transmitting in custom Wiegand mode (refer memory 132).
These are the bits that will be transmitted when the data bits
(including site, user & parity) are not being sent.
