Engineering guides & operational documentation.
Authoritative guides for workstation deployment, bidirectional RS-232 analyzer interfacing, offline Ed25519 digital signature activation, and zero-loss database backup procedures.
LensNew Optical BOS — Workstation Deployment
Complete workflow for deploying LensNew on standalone showroom terminals or local area network (LAN) store clusters.
Download Installer & Verify SHA-256 Checksum
Retrieve the installer from the Customer Portal or direct authorized distribution link. Compute the file's SHA-256 hash using Windows PowerShell to verify cryptographic integrity prior to execution:
Confirm that the resulting hash strictly matches the published digest on our official Release Notes page.
Run Self-Contained Runtime Installation
Execute LensNew_Optical_Setup.exe with Administrator privileges. The installer sets up:
- Embedded pure-Go web engine and background processing daemon.
- ACID SQLite storage engine configured with Write-Ahead Logging (WAL) for concurrency.
- Desktop shortcuts and Windows Service auto-start hooks.
Configure Store Identity & GSTIN Parameters
Open LensNew from your desktop shortcut or navigate to http://127.0.0.1:8090 in any modern browser. Open Settings → Showroom Profile:
- Trade Name & Address: Appears on thermal and A4 tax invoices.
- GSTIN: Sets automated CGST/SGST (intra-state) or IGST (inter-state) calculation.
- Invoice Prefix & Serial: Configure custom invoice sequencing (e.g.,
LENS-2627-0001). - Thermal Header / Footer: Store policy notes, return terms, and QR code for UPI payments.
Thermal Receipt & Barcode Scanner Setup
LensNew communicates directly with ESC/POS standard thermal printers and 1D/2D USB HID scanners with zero third-party drivers needed:
UBVY Pathology App — Clinical Setup & Serial Interfacing
Bidirectional serial communication protocol setup for hematology, biochemistry, and electrolyte clinical analyzers.
Physical Cable Connection & FTDI Serial Chipset
Connect the analyzer's RS-232 DB9 serial port to the laboratory PC using an industrial FTDI-chipset USB-to-RS232 adapter cable. Verify the assigned port in Windows Device Manager:
Serial Port Parameter Mapping
In UBVY Pathology App, navigate to Laboratory Administration → Instrument Telemetry Interfacing. Configure the serial channel according to your instrument manufacturer's documentation:
| Analyzer Model | Baud Rate | Data Bits | Parity | Stop Bits | Protocol Format |
|---|---|---|---|---|---|
| Mindray BC-3000 Plus | 9600 | 8 | None | 1 | ASTM E1381 / E1394 |
| Erba Chem-7 / Chem-5X | 9600 | 8 | None | 1 | Raw ASCII Delimited |
| Horiba ABX Micros 60 | 9600 / 19200 | 8 | None | 1 | ASTM Standard |
| Roche Cobas C111 | 9600 | 8 | None | 1 | HL7 v2.3 / ASTM |
Automated Telemetry Capture Verification
Run a sample or control vial through the analyzer. The UBVY Pathology real-time serial listener will detect the incoming transmission, parse the test parameters (e.g., WBC, RBC, HGB, PLT), and immediately bind them to the matching patient barcode worklist.
Offline Ed25519 Cryptographic Licensing Protocol
How UBVY Group desktop products achieve 100% offline security, zero recurring server pings, and cryptographically verified hardware binding.
Hardware Factor Fingerprint Extraction
Upon initial launch, the application extracts immutable hardware identifiers and computes a canonical SHA-256 device fingerprint:
- Motherboard Serial Number (WMI / DMI table).
- Root Storage Drive Physical Serial Number.
- Windows Machine UUID / Machine-ID.
- Root Volume Serial Number.
Digital Signature Generation (.ubvysig)
Upon verified payment confirmation, the UBVY Group protected signing engine creates a signed canonical JSON envelope:
Instant Local Activation
In the desktop application activation dialog, click "Import .ubvysig File". The software verifies the digital signature using its embedded master Ed25519 public key and unlocks all licensed modules instantly.
ACID Database Backups & Zero-Loss Recovery
Protecting store ledgers and clinical records with atomic SQLite snapshots and automated offsite replication.
1-Click Atomic Online Snapshot
Both LensNew and UBVY Pathology App feature atomic backup capabilities that freeze no transactions and cause zero downtime. In the software, click System Settings → Database Maintenance → Backup Now:
This creates a clean, fully compacted, and uncorrupted SQLite snapshot even while cashiers or lab technicians are actively writing records.
Restoration Procedure
In the rare event of severe operating system corruption or hardware replacement:
- Install a fresh copy of the application on the new workstation.
- Stop the background service from Windows Services (
services.msc). - Copy your verified
.dbsnapshot file into the application data directory. - Restart the service. All past customer invoices, prescriptions, and inventory records are restored immediately.
