OSDP ↔ Wiegand Protocol Converter | SIFER Reader Integration | Integriti & Inception Access Control
The Inner Range OSDP to Wiegand Converter IR-994200 is a compact, bidirectional access control interface designed to convert OSDP reader data to Wiegand format and Wiegand reader data to OSDP-compatible communication. Featuring support for Inner Range SIFER readers, RS-485 communication, 128-bit AES encryption on supported OSDP links and configurable reader settings, this versatile converter enables integration between legacy Wiegand access control hardware and modern Inner Range Integriti and Inception security systems across Australia and New Zealand.
Manufactured by Inner Range, the IR-994200 is designed to simplify access control upgrades and improve compatibility between different reader communication formats without requiring the immediate replacement of all existing access control hardware.
The converter operates in two principal modes. It can connect traditional Wiegand readers to compatible Inner Range OSDP reader ports, or connect supported OSDP readers, including Inner Range SIFER readers, to existing Wiegand reader inputs.
When connecting Wiegand readers through the supported Inner Range OSDP interface, installers can benefit from longer supported RS-485 cable runs, flexible reader-bus configurations and encrypted communication between the converter and controller. Existing Wiegand readers can also retain control of their beepers and valid or invalid LED indicators.
For security system upgrades, the converter allows compatible SIFER and selected third-party OSDP readers to interface with Wiegand reader inputs, providing a practical migration path for installations incorporating older access control equipment.
The device also offers automatic reader enrolment in OSDP-to-Wiegand mode and configurable communication and reader settings through a compatible Port 0 programming cable.

What's Included in the Box
-
1 × Inner Range OSDP to Wiegand Converter – IR-994200.

Bidirectional Conversion and Integration
The IR-994200 provides two useful deployment configurations.
Mode 1 – Wiegand Reader to OSDP Interface
Connect existing Wiegand readers to compatible Inner Range RS-485 reader buses and retain supported LED and beeper control functionality.
Mode 2 – OSDP Reader to Wiegand Interface
Use compatible modern OSDP readers with suitable Wiegand-input access modules during phased system upgrades.
Conceptual signal flow only. The converter is designed for supported Inner Range configurations and is not a universal third-party OSDP bus adapter.
Practical Use Scenarios
Legacy access control system upgrades
Retain existing compatible Wiegand readers while migrating an installation to supported Inner Range Integriti equipment.
SIFER reader retrofits
Connect supported Inner Range SIFER readers to existing Wiegand inputs where the controller and converter configuration permit.
Commercial office buildings
Upgrade access control reader connectivity across office entrances and restricted areas without unnecessarily replacing functional reader hardware.
Industrial and warehouse facilities
Integrate supported older reader installations with newer security infrastructure, reducing the amount of hardware that needs replacing during system improvements.
Multi-door access installations
Expand reader connection flexibility using supported RS-485 configurations, particularly where multiple Wiegand readers must connect to an Inner Range access module.
Educational and institutional facilities
Support staged access control modernisation while maintaining compatible legacy reader installations during the transition.
Integriti expansion projects
Connect compatible Wiegand or OSDP readers to Integriti SLAM, ILAM or IAC modules according to the supported reader-port architecture.
Compatibility and Installation Requirements
The Inner Range IR-994200 OSDP to Wiegand Converter is intended for professional access control installations using compatible Inner Range reader and controller configurations.
In Wiegand-to-OSDP mode, it is designed to interface with supported Inner Range serial reader ports, including those on compatible Integriti SLAM, ILAM, IAC and Inception controllers.
In OSDP-to-Wiegand mode, it supports Inner Range SIFER readers and selected third-party OSDP readers. Compatibility with third-party reader models, firmware and operating modes must be confirmed before installation.
Important security consideration: Although the supported OSDP communication segment can use AES-128 encryption, the conventional Wiegand segment remains unencrypted. The converter does not make the entire communication path end-to-end encrypted.
Installation also requires the appropriate power supply, reader wiring and configuration. Some 5V Wiegand readers require additional installation considerations, covered in the manufacturer's dedicated manual.
Warranty Information
The IR-994200 is subject to applicable Inner Range manufacturer warranty conditions and statutory consumer guarantees.
A specific manufacturer warranty duration has not been independently verified and should be confirmed with the authorised supplier.
Warranty assessment and technical support may be coordinated with Inner Range through the appropriate distribution arrangement, subject to applicable manufacturer conditions.
