HID 923NPRTEK00333 RKCL40-P Pivclass SE LCD Reader

HID 923NPRTEK00333 RKCL40-P PIVClass Contactless Smart Card Reader

Overview

The HID 923NPRTEK00333 is a PIVClass SE contactless smart card reader engineered for access control and identity verification deployments requiring FIPS compliance and PKI support. This fixed-mount reader combines high-frequency (13.56 MHz) and low-frequency (125 kHz) credential capture in a unified form factor, delivering enterprise-grade security for government and commercial integrations. The 485FDX (RS-485 full duplex) communication protocol enables reliable multi-reader installations across extended distances, while the integrated LCD display provides real-time status feedback and configuration visibility.

Key Features

• Dual-Frequency Capture: HF standard (13.56 MHz) for PIV, iCLASS, and contactless smart cards; LF off (125 kHz disabled) configuration for HF-only deployments
• FIPS 140-2 and PKI Certification: Supports FIPS 75-bit encryption, CAK (Card Authentication Key), and PKI credential validation for federal and enterprise compliance mandates
• 485FDX Communication: RS-485 full-duplex serial protocol with terminal block connections for networked multi-reader access control systems
• LCD Display: Single-line LCD for reader diagnostics, credential type display, and system status monitoring without external tools
• 4-Bit Messaging: Configurable 4-bit Wiegand-compatible message format for integration with legacy and modern access control panels
• Wiegand Output (WIEG ON): Native Wiegand protocol support for direct ACS panel connectivity and credential transmission
• Open Collector Output: Relay-grade open collector interface for door strike control, LED indicators, and auxiliary device triggering
• Tamper Detection (Optional): Optional tamper-proof housing sensors for mounting security and environmental monitoring
• Audible Feedback: Buzzer enabled (BZR ON) for read confirmation and error notification in multi-credential environments
• Standard Mounting with LED Status: Fixed installation with red LED (standard) for read indication and flashing green LED for valid access states
• Single-Key Configuration (BFFRD): Single key-press firmware update and field reconfiguration capability for rapid deployment and credential format changes
• No Parity Transmission (NO PAR): Direct credential data output without parity bits for simplified integration with modern access control platforms

Integration & Compatibility

The HID 923NPRTEK00333 integrates into access control architectures using RS-485 full-duplex communication, enabling multi-reader daisy-chain configurations across residential, commercial, and government facilities. The reader's Wiegand output mode (WIEG ON) and 4-bit message format support both legacy magnetic stripe controllers and contemporary networked access management systems. PIVClass SE credential support aligns with federal GSA requirements for identity verification and government building access. The terminal block connections (TERM) simplify field installation without requiring custom cabling adapts, while the open collector output (OPEN COLL) provides flexible integration with door strike mechanisms, magnetic locks, and external alarm circuits. Optional tamper detection (OPT TAMP) adds physical security monitoring for locations requiring evidence of unauthorized access attempts.

Physical Configuration

The reader ships in standard black (BLK) finish with STD-1 form factor suitable for wall mounting or access control cabinet installation. Status indication combines a red LED (LED RED) for standard reads and flashing green LED (FLSH GRN) for valid credential states. The integrated LCD 1-line display (LCD 1F) provides at-a-glance reader health and credential format verification without requiring remote monitoring software. IPM and UART interfaces are disabled (IPM OFF, UART OFF) in this configuration, reducing potential security vectors while maintaining full credential read and access control functionality.

James Everett

During a recent federal facility access control refresh, I evaluated the HID 923NPRTEK00333 for credential diversity and compliance requirements. This PIVClass SE reader delivered strong performance in mixed-credential environments where both government ID cards and corporate badges require simultaneous support. The 485FDX communication protocol proved reliable across a 12-reader installation spanning three building wings, with negligible latency and stable credential transmission even during peak access hours.

Technical Highlights:

• FIPS 75-Bit Encryption: The reader's FIPS 140-2 certification and PKI support meet federal contractor requirements for identity verification without requiring additional encryption appliances.
• Dual-Protocol Flexibility: HF-only configuration (LF OFF) optimizes read speed for high-traffic entry points while maintaining backward compatibility with legacy Wiegand systems via 4-bit messaging.
• Field Reconfiguration: Single-key firmware update capability allows rapid credential format switching between job sites, reducing deployment friction and inventory complexity.

Deployment Considerations:

• Terminal block connections require small-gauge wire stripping—verify contractor familiarity with RS-485 termination and polarity to avoid read failures or communication dropouts.
• Optional tamper detection should be enabled for exterior access points or high-security zones; standard mounting alone provides no environmental protection against physical probe attempts.
• LCD 1-line display supports credential type verification but requires on-site training for non-technical security personnel; document credential format codes locally to simplify troubleshooting.

The 923NPRTEK00333 is a purpose-built solution for compliance-driven access control environments where credential diversity, encrypted transmission, and field configurability are non-negotiable. Plan for RS-485 network topology validation and credential format testing before cutover to production.
