INTRODUCTION
The Presco Interface Module (PIM) can be used to
convert commonly used data formats to NIDAC Presco,
USB, RS232, Clock & Data or Wiegand format data.
FEATURES
•
Converts from Wiegand, RS232, USB, NIDAC
Presco, Clock & Data (Magnetic Card) or Dallas
iButton (commonly referred to as Silicon Key)
format.
•
Converts to NIDAC Presco, RS232, USB, Clock &
Data (Magnetic Card) or Wiegand format.
•
Can convert to or from Wiegand with up to 128 bits
of data, including up to 32 bit site code plus
optional start and end parity bits.
•
User programmable site code when converting to
Wiegand.
•
Reads up to 128 bits from Dallas iButton user
memory or 64 bits from factory ID.
•
Reads up to 32 characters or digits from Track 1, 2
or 3 Clock & Data (magnetic card) format input.
•
User programmable settings using standard Prove
keypad or via USB-C link (software for USB
programming, PIMs4, is available from NIDAC
’s
•
Compatible with all current NIDAC Prove encoders
and Presco controllers.

TERMINAL DESCRIPTIONS
+12V DC
The positive D.C. power input.
GND
The Ground (or Negative) power input.
This is also a common reference
connection for all devices connected to
the PIM. i.e. all devices connected to the
PIM require their GNDs to be connected
together.
DTA
Presco data input/output.
IN-A
Input A (Wiegand D0, Clock & Data RDP
or iButton).
IN-B
Input B (Wiegand D1 or Clock & Data RCP).
OUT-A
Output A (Wiegand D0 or Clock & Data
RDP).
OUT-B
Output B (Wiegand D1 or Clock & Data
RCP).
RX
The RS232 Receive input.
TX
The RS232 Transmit output.
CTS
The RS232 CTS input.
RTS
The RS232 RTS output.
