Proper deployment of the Biomax N-X90 GPRS standalone biometric terminal ensures reliable time attendance logging and secure physical access control across corporate offices, industrial sites, and commercial facilities. The hardware installation workflow encompasses mechanical mounting, direct 12V DC power connection, door relay interfacing, peripheral trigger wiring, and data network integration.
Mounting and Physical Placement
The terminal features an enclosure footprint measuring 160 mm in length, 140 mm in height, and 65 mm in width. Install the unit on a flat, vibration-free vertical wall or mounting plate at an ergonomic operating height to allow clear viewing of the 2.4-inch TFT LCD color screen and comfortable interaction with the 500 DPI optical fingerprint sensor.
Ensure the installation location remains within the certified operating temperature boundary of 0°C to 50°C. Avoid exposing the optical biometric sensor to intense outdoor direct glare or heavy ambient moisture to maintain consistent scan read rates under 1 second.
Power Supply Requirements
The Biomax N-X90 GPRS requires a regulated external operating supply of 12V DC at 2A. Maintain proper polarity when wiring the power leads into the terminal's power terminals to avoid electrical damage to the internal embedded Linux hardware architecture.
The terminal features an inbuilt battery backup system to sustain operation during primary power interruptions. When laying power conduit, keep low-voltage 12V DC runs isolated from high-voltage AC mains lines to minimize electromagnetic noise and voltage drops across extended cable runs.
Door Access Control and Peripheral Wiring
The device includes an integrated door open output relay designed to actuate standard electronic locking hardware, such as electronic strikes, drop bolts, and magnetic locks:
- Lock Relay Output: Connect the internal relay contacts in series with the lock power circuit to manage lock open pulses triggered by valid biometric, card, or password identification.
- Request-to-Exit Connectivity: Wire external egress controls directly to the terminal's designated auxiliary inputs. The terminal natively supports standard push buttons, manual exit switches, no-touch infrared sensors, and remote release modules.
Data Network Configuration and Communication Setup
The Biomax N-X90 GPRS offers flexible data transmission topologies to accommodate local networks and remote standalone locations:
- TCP/IP Ethernet: Terminate standard RJ45 networking cable into the LAN port for integration into local enterprise networks. Assign a static IP address or configure network addressing via the on-screen menu interface.
- 2G GPRS Cellular: Insert an active SIM card into the internal cellular module to communicate attendance data over 2G mobile networks, ideal for branch locations or remote operations lacking wired network drops.
- Push Data Server Protocol: Configure the server IP and port settings in the device menu to enable automatic real-time transaction forwarding via Push Data protocol to Biomax desktop, web, or cloud management software platforms.
- USB Host Transfer: Utilize the onboard USB host interface for manual offline retrieval of transaction log files and user template distribution using compatible flash memory drives.
