The digital reporting companion for your LTI gamma counter. Every report your instrument prints — wipe tests, calibration summaries, AutoSpect™ spectra, decay calculations, daily QC, RIA assays — captured directly to a properly named PDF, filed into a searchable archive, optionally printed to any networked office printer, and exportable as CSV to your LIS or LIMS. The dot-matrix data path, replaced by software that runs on the lab’s existing PC. No subscription. No phone-home. One-time license per organization.
Every LTI gamma counter ships with a serial printer port. For decades that port has fed a parallel-port dot-matrix printer. That worked fine in 1990. In 2026, it’s a friction point — ribbons are getting hard to source, paper records have to be scanned by hand to satisfy modern audits, and your LIS or LIMS can’t ingest a printout. LTI Capture replaces that printer with software. Plug in a USB-to-Serial cable, install the application, click Start capture. From that moment on, every report your instrument prints becomes a properly named PDF, filed automatically, ready for whatever your workflow needs next.
Every report the instrument would have printed becomes a PDF on your computer instead — bit-for-bit. No interpretation, no abridgment, no re-derivation. Wipe tests, calibration summaries, AutoSpect™ spectra, daily QC, decay calculations, RIA assay reports — all captured exactly as the instrument intended them.
Every captured PDF lands in an organized folder structure of your choosing: by date, by report type, or both. Built-in archive browser with live filename search means a report from three years ago is fifteen seconds away — no fanfold paper, no filing cabinets, no boxes of scanned PDFs.
Lab uses an LIS or LIMS? Enable CSV export — every report appends a structured row to a master log, or writes a per-report CSV alongside the PDF. Need paper too? Route to any printer the OS can see — any modern office printer replaces the dedicated dot-matrix. All three outputs run together if you want.
From that point on, every report your instrument prints catches in real time. LTI Capture identifies what kind of report it is, names it intelligently (e.g., WipeTest_HotLab_W01-W08_2026-05-14_14-23-07.pdf), and routes it according to your preferences. The operator runs their test, hits the instrument’s Print key, and the PDF appears on the right printer, in the right folder, with a record in their CSV. The user never has to do anything per-report.
LTI Capture isn’t a generic serial-port logger. It parses the actual byte-level dialect of every LTI counter, recognizes report boundaries semantically, names files intelligently, and ships with workflow features that didn’t exist in the paper era.
Every LTI counter announces its model and firmware version over the printer port at power-on. LTI Capture detects this announcement, strips it from the byte stream so it doesn’t accidentally appear in the first captured report, and shows the identified model in the UI. Tip: start LTI Capture before powering on the instrument so this self-identification always fires.
LTI Capture parses the instrument’s actual ESC/P dialect and runs an op-based recognizer derived from reading the firmware source code itself. Each printed report is recognized as a distinct logical document and named with full context — WipeTest_HotLab_W01-W08_2026-05-14_14-23-07.pdf, CalibrationSummary_I125_2026-05-14_09-15-22.pdf, SystemEffCheck_LOT-4449_2026-05-14_10-10-57.pdf. Multi-tube sessions merge automatically. Spectrum prints, daily QC, background counts, assay protocol summaries, curve fits, unknown-tube tables, controls/references/standards — all recognized natively.
A multi-tube wipe test or multi-sample CPM session can take minutes — finish a tube, print, finish the next, print. LTI Capture reads the COUNT TIME field from the report and uses an adaptive wait-time formula before declaring the session complete: a 30-second count is wrapped up ~60 seconds after the last byte; a 5-minute count gets the full safety margin.
Want to close out a session immediately? Press the C key on the instrument’s keypad. LTI Capture treats the form-feed character it sends as “session complete” and the PDF lands within a second.
If the USB-to-Serial cable gets bumped, the OS suspends the port, or the instrument is power-cycled mid-session, LTI Capture doesn’t terminate the capture. It logs the loss, retries on a backoff schedule (1 s, 2 s, 5 s, 10 s), and resumes transparently when the port comes back. The user never has to notice or restart anything.
Default printer, named printer, or pick one per session. macOS, Windows, and Linux all use their native print stacks — network printers, local USB printers, AirPrint, IPP — anything the OS supports, LTI Capture supports. No printer-driver friction.
Copy every captured PDF into a folder structure of your choosing: by date (2026-05-14/...), by report type (WipeTest/, CalibrationSummary/, DailyQC/), or by date and type (default). Built-in archive browser lets you search any of those organized folders by filename or date fragment, open in your default PDF viewer, or re-print one or many to your office printer.
For laboratories with an information system or any kind of database integration. Master-log mode appends one row per captured report to a single CSV. Per-job mode writes a CSV file alongside each PDF. Patient data, wipe-test results, calibration logs — all flow into your LIS without manual transcription.
New in v1.0. The technician flags a suspicious capture; a red banner appears across the LTI Capture window; the supervisor walks over, clicks the banner, reviews the PDF, picks a decision (Authorize / Re-run the wipe test / Other) and adds notes. LTI Capture appends a Flag and Resolution Record page to the PDF itself. The audit trail travels with the document — into the compliance binder, into the regulatory archive, into the QA review six months later.
Every captured page carries an unobtrusive footer: “Licensed to [Your Organization]” on activated copies; a larger red “UNLICENSED COPY — Not for Regulatory or Audit Use” watermark on any copy that hasn’t been registered against an order. The PDF identifies its own provenance.
LTI Capture does not communicate over the network. Activation is a plain-text email exchange the customer can audit line by line. Once activated, the application runs entirely offline. Hospital IT can answer “does this software phone home?” with a clean no.
v1.0 includes detection hooks for upcoming firmware-side capabilities: LTI-OPERATOR: stamps the logged-in technologist on every PDF footer; LTI-FLAG: auto-flags a report from the instrument keypad; LTI-ADMINS: populates the supervisor dropdown from the instrument’s user list; LTI-REPORT-TYPE: classifies bitmap-only reports. When the firmware ships, LTI Capture picks them up automatically — no software update required on the customer side.
Click About in the header to see the installer ID, license state, OS version, and diagnostic-log location. The Copy diagnostics button puts a structured bundle (version, license, last 150 lines of today’s activity log) on the clipboard — ready to paste into a support email. LTI sees exactly what the app saw.
LTI Capture’s UI is designed to feel like part of the same product family as labtechinc.com: clean navy and cyan, Inter typeface, minimalist hierarchy, no marketing renders. These are screen captures of the actual v1.0 application running on macOS.
CalibrationSummary, HotLab, 2026-05, anything that appears in a filename or folder. Open one (default PDF viewer) or Print selected (native print dialog with full printer choice).
LTI Capture identifies each connected instrument automatically — the unit announces its model and firmware version on power-on. The application picks the right report-recognition rules for that instrument without configuration. Current support and the next-release roadmap below.
Validated against real Wiper Gold hardware running firmware v3.18.
RIA-specific report types (assay protocol summaries, curve fits, unknown-tube tables, controls/references/standards summaries) included in the next-release support. ETA: within weeks.
The Genesys 5000 is end-of-life and uses a printer-port protocol that predates the current LTI counter family. We’re not planning to add 5000 support — legacy 5000 service continues through LTI direct.
FTDI, Prolific, CH340, or any standard-chipset USB-to-Serial adapter. One is included in every shipping box. The instrument side is DB9 on current-production units; legacy installed-base counters with a round connector are supported via an LTI-supplied custom cable.
The same port the dot-matrix printer connects to today. No firmware change. The instrument doesn’t know LTI Capture is there — it just thinks a printer is listening, the same way it always has.
The custom cable + USB-to-Serial adapter combination means LTI Capture is compatible with every LTI counter ever shipped within the supported product list above. The legacy installed base is the primary target market — you don’t need to buy a new instrument to digitize your records.
LTI Capture ships as a physical package, not a download link. The installer is on a branded LTI USB drive. The USB-to-Serial cable is in the same box. A Certificate of Authenticity on LTI letterhead confirms the binary’s SHA-256 hashes for your IT department.
The cable replaces the existing dot-matrix printer connection. If your existing dot-matrix is still on a Y-cable, LTI Capture is purely a parallel listener and doesn’t interfere with the other branch.
The drive contains installers for macOS, Windows, and Linux. Copy the right one to your machine and launch it. macOS: drag LTI Capture.app into Applications. Windows: copy the program folder somewhere permanent (e.g., C:\Program Files\LTI Capture\) and double-click LtiCapture.exe. Linux: chmod and run.
Welcome → Connect (pick the port) → Outputs (Print / Save / CSV) → Register (organization + email) → Done. The wizard takes about one minute. At the end you’re back on the main window with a port selected, outputs configured, and ready to capture.
The wizard generates a plain-text registration block — readable by your IT and compliance teams before sending. Email it to registration@labtechinc.com. LTI replies within one business day with a 12-character activation code (LTI-XXXX-XXXX-XXXX). Paste it into the app and click Verify. The UNLICENSED COPY watermark is replaced with “Licensed to [Your Organization]” on every PDF from that point on.
Any printout works — a daily QC, a wipe test, a screen print. The PDF appears in your archive folder within seconds. You’re live.
Some IT departments require pre-installation review of any new desktop application. LTI provides a polished IT Approval Bundle (PDF) that documents what LTI Capture does, what data it touches, what it sends over the network (nothing, after activation), and the SHA-256 hashes of the binaries. The bundle is included in every shipping box and is available on request.
LTI Capture runs on any modern desktop OS. Resource footprint is intentionally small — under 100 MB of memory at idle, no background services, no system-tray daemon. It’s designed to sit on the same computer that already runs your other lab software without competing for resources.

LTI Capture is a one-time-purchase, no-subscription license. The customer pays once and owns it. LTI Capture ships as a physical kit — branded USB drive, USB-to-Serial cable (custom cable for legacy instruments), Certificate of Authenticity on LTI letterhead, and printed IT-approval bundle — not as a web download.
One license activates LTI Capture for an entire organization — no machine-by-machine activation, no seat counting. A customer with five lab PCs uses one license. They activate it once on any of their machines with their organization name.
Includes:
Contact us for current pricing. Foreign-distributor payment terms: 100% wire with PO for new or small-relationship customers.
LTI’s distributors purchase blocks of activations: 10, 50, or 100 per pack. Each pack is a single custom-built installer that tracks activations centrally. As the distributor sells units, the activation slots are consumed. When the pack runs out, the distributor reorders.
How it works:
Distributor pricing on request. Contact LTI Sales for the current pack rates and onboarding pack.
The majority of the LTI counter installed base predates the current DB9 serial connector and uses a legacy round connector that LTI Capture talks to via a custom USB-to-Serial cable LTI supplies in every kit. Without that cable, the software has nothing to listen to — which is why we don’t distribute LTI Capture as a download.
The physical kit also addresses the trust question hospital and clinical-lab IT departments ask first: where did this binary come from? Branded LTI USB drive, signed Certificate of Authenticity on LTI letterhead, SHA-256 binary hashes, and an IT-approval bundle ship in the box. Came on an LTI USB stick with a Certificate of Authenticity is a much stronger story for IT review than downloaded from a website.
Everything you need for IT review, distributor training, or just to read up before talking to us.
Three-page customer-facing overview. What it does, what problem it solves, what’s in the box, who it’s for. Good handout for hospital procurement teams and prospective customers.
Complete operator’s manual. Installation on macOS / Windows / Linux. Setup wizard. License activation. Capture workflow. Archive browser. Supervisor-review workflow. Diagnostics. Troubleshooting. Illustrated with real screen captures.
For hospital and clinical-lab IT review. Documents what LTI Capture does, what data it touches, what it sends over the network (nothing after activation), and the binary SHA-256 hashes. Available on request — we’ll send it the same day.
LTI Capture pairs naturally with the Wiper Gold — the compact single-detector wipe counter with 4096-channel MCA, AutoSpect™ spectrum compensation, and the same digital-first workflow positioning. See the full product page.
