Presco
Nidac Presco Series 4 Reader Interface Module Presco Interface Module (PIM)
The Presco NPOPIM (Presco Interface Module - PIM) is a data format converter used to translate commonly used access control reader and peripheral formats into the required format for the target device. It can also be used for database backup and upload tasks for Presco access controllers (PAC controllers) when connected to a personal computer (PC) via a Universal Serial Bus Type C (USB-C) interface.
Key Features
- Converts multiple access control data formats to suit the connected device.
- 12 Volt direct current (DC) operation.
- Universal Serial Bus Type C (USB-C) connectivity for personal computer (PC) interfacing.
- Supports Wiegand formats up to 128 bit, including site codes up to 32 bit (with optional parity bits).
- Reads Dallas iButton user memory (up to 128 bit) or factory identification (ID) (64 bit).
- Reads magnetic stripe Clock and Data inputs (Track 1, 2 or 3) up to 32 characters or digits.
- Supports database backup from a Presco access controller (PAC controller) and upload to remote controllers.

- 1 × Presco Interface Module (PIM)
Suitable Uses
- Converting Wiegand reader outputs to suit Presco access controllers (PAC controllers).
- Converting Presco to Wiegand for cable runs beyond 100 m or where interference is present, then converting back to Wiegand at the controller end.
- Integrating non-Wiegand peripherals with Wiegand controllers via conversion.
- Database backup from Presco access controllers (PAC controllers) and uploading databases to controllers at remote sites.
- Supporting multi-format environments using Presco, Wiegand, Clock and Data, Dallas iButton, RS-232 or USB devices.
Frequently Asked Questions
- Can this module convert Wiegand to Presco and then back to Wiegand?
Yes. It supports conversion between Wiegand and Presco, including use cases for long cable runs or high interference environments. - What power supply is required?
The module operates on 12 Volt direct current (DC). Ensure the supply is correctly regulated for access control electronics. - Is this used only for reader conversion?
No. It can also be used for database backup from a Presco access controller (PAC controller) and for uploading databases into controllers at remote sites when connected to a PC via USB-C.
Additional Information
- In mixed-format sites, data conversion is often used to standardise reader signals and reduce troubleshooting when different controllers and readers are used across the same project.
- For long cable runs or noisy electrical environments, installers commonly prioritise correct cable type, shielding, and earthing practices to minimise data errors before relying on format conversion alone.
- When working with Wiegand bit lengths and site codes, confirm the controller’s accepted format settings before commissioning, especially on 64 bit and 128 bit configurations.
