PV-COM® reads your scale's weight and automatically sends it to any Windows application. Compatible with all types of scales. PV-COM® is also known as PVCOM or PV COM in many countries.
Main PVCOM integrations
The software in action
PV-COM captures the scale's signal and displays it cleanly, ready to send to any application.
Does this sound familiar?
Millions of businesses still type weights by hand.
Every scale has someone reading the number and typing it in. Slow, costly, and constantly error-prone.
Windows doesn't recognize your scale. The manufacturer has no driver. Your POS system doesn't detect it.
No weighing history. Impossible to audit, report, or analyze without accurate, automatic data.
Complete solution
PV-COM® captures, filters, transforms, and sends the weight wherever you need it — without a single line of code.
The weight appears automatically in the active field of any application, as if you typed it yourself. Compatible with any Windows software.
RS-232 · USB · HID
Creates virtual COM ports and redirects RS-232 scale data to applications expecting a serial port. Works as a transparent driver.
Virtual COM
Saves every weighing to MySQL, Excel, Google Sheets, or TXT with a timestamp. No manual intervention. Complete history for audits.
MySQL · Excel · Sheets
Emulates the output protocol of different brands. If your software expects a CAS scale, PV-COM makes your scale "speak" like a CAS.
Protocol emulation
Connect several scales at the same time on one computer. Ideal for distribution centers, laboratories, or industrial plants.
Multi-scale
Logs weight behavior over time with live charts. Exports to Excel. Ideal for quality control and process monitoring.

Technical glossary
PV-COM is a Windows software that connects RS-232, USB, and HID electronic scales to any application: Odoo, Excel, MySQL, point-of-sale systems, and browsers. It works as a driver, keyboard emulator, and virtual COM port emulator, eliminating manual weight entry.
PV-COM connects RS-232 or USB scales to Odoo without the IoT Box. It works as a keyboard emulator that sends the data directly to the Odoo form. Saves more than $300 USD in additional hardware.
A virtual COM port is a software-simulated serial port. PV-COM creates it on Windows so applications expecting RS-232 data can receive it even if the scale is connected via USB. It solves the incompatibility between older scales and modern software.
PV-COM can connect to a MySQL 5.7 or MySQL 8 table so that, with the click of a button, every weight reading is saved to MySQL with date and time. No coding required: just configure the connection parameters and the software logs every weighing.
PV-COM lets you use RS-232 and USB scales without an official driver on Windows 11, from brands like Torrey, CAS, Mettler Toledo, Dibal, Ohaus, Fairbanks, Dymo, Magellan, Moresco, Rochi, and more than 200 additional models.
An HID (Human Interface Device) driver lets Windows recognize a USB scale as an input device. PV-COM works as an HID driver for USB scales that Windows doesn't recognize natively, like some Dymo, Fairbanks, and other weighing brands.
