Proper deployment of the Biomax N-X990 biometric time-attendance and door access control terminal (KT stock code KTI01001002X990) requires systematic planning of mechanical mounting, electrical power distribution, door hardware connections, and network communication routing. Designed for standalone or networked commercial installations, the 0.8 kg terminal features an integrated wall-mount enclosure measuring 215 mm (L) × 160 mm (H) × 45 mm (W).
Mounting Location and Environmental Planning
The unit must be securely affixed to a flat vertical surface, such as an interior masonry wall, structural partition, or mounting bracket assembly. The operational environment must stay strictly within the rated operating temperature window of 0°C to 50°C. Protect the terminal's optical glass fingerprint sensor prism and 3.0-inch color touch screen from direct high-intensity light glare, excessive atmospheric dust, grease, and industrial moisture.
For ergonomic optical alignment and natural hand positioning over the 500 DPI optical biometric scanner, consider personnel stature during mounting. Personnel ranging between 1.55 m and 1.85 m (5 to 6 feet) in height should stand approximately 0.5 m (2 feet) away from the wall-mounted terminal when clocking in or navigating the Linux-driven interface.
Power Supply Requirements
The terminal requires a clean, regulated direct-current power source:
- Operating Voltage and Current: Direct wiring to a dedicated 12V DC, 2A regulated power supply adapter or access control power distribution cabinet.
- Polarity and Cable Runs: Maintain strict polarity on the DC terminals. Voltage drop across long-distance cable runs should not fall below terminal operational tolerances.
- Mains Failure Protection: If continuous verification is required across plant power disruptions, deploy the terminal with an optional backup battery (they are not included) or wire it to an uninterruptible power supply cabinet.
Access Control Terminal Wiring and Peripheral Integration
The rear access interface provides terminal blocks for door hardware, egress control peripherals, and slave readers. The internal relay switches door lock circuits directly or through interposing contactors:
- Electronic Door Lock Output: Connect fail-secure or fail-safe electromagnetic locks and electric dropbolts across the integrated relay dry contacts.
- Egress Control Devices: Connect standard exit push buttons or touchless infrared exit sensors to the exit button input terminals for localized release.
- External Reader Integration: Integrated Wiegand inputs and outputs support 26-bit, 34-bit, and custom data formats for external proximity readers. For dual-side door security, wire external Wiegand readers or RS485 slave readers to the designated serial communication ports.
- Canteen Peripheral Setup: When integrating the unit into institutional cafeteria systems, connect an external thermal slip printer directly to the onboard RS232 serial interface.
Network and Data Communication Configuration
The Biomax N-X990 offers multiple network interfaces for data synchronization and firmware communication:
- Ethernet (TCP/IP): Terminate an IEEE 802.3 compliant CAT5e/CAT6 network cable into the RJ45 port for hardwired local area network transmission.
- Wi-Fi Communication: For installations where structured cabling is cost-prohibitive, configure the embedded 802.11 Wi-Fi interface to join corporate wireless networks.
- Direct and Offline Data: Utilize the onboard USB host and client ports for direct workstation link or manual attendance record retrieval using portable flash storage.
- Push Data Technology: Once IP addressing is established, enable the push data service to stream punch records and transaction logs directly to centralized management servers in real time.
Post-Installation Testing and Screen Calibration
After completing power and peripheral termination, power on the terminal to verify the Linux boot sequence and 16-bit Hi-Fi English voice prompts. If finger taps show misalignment on the 3.0-inch TFT display, execute the built-in 5-point touch calibration utility via the terminal navigation menu: navigate to [Menu] > [Auto Test] > [Calibration] and tap the highlighted target points in sequence.
