PV-COM® reads the weight from your RS-232, USB or HID scale and sends it automatically to Odoo, Excel, MySQL, point-of-sale systems and more. 200+ compatible models.
Compatible with these systems and applications
Software in action
PV-COM captures the scale signal and presents it cleanly, ready to send to any application.
Does this sound familiar?
Millions of businesses still type weights by hand. Every mistake is a real financial loss.
Someone reads the scale, writes the number. Slow, expensive and full of human errors.
Windows doesn't recognize your scale. No official driver. Your POS system can't detect it.
No weighing log. Impossible to audit, report or analyze without accurate automated data.
Connecting one scale to Odoo requires expensive hardware. PV-COM does it in software only.
Complete solution
PV-COM® captures, filters, transforms and sends the weight wherever you need it — no coding required.
The weight appears automatically in the active field of any application, as if you typed it yourself. Works with any Windows software.

Technical glossary
PV-COM is Windows software that connects RS-232, USB and HID scales to any application — Odoo, Excel, MySQL, POS 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 19 without the IoT Box. It works as a local weight server or keyboard emulator, sending the weight directly to Odoo form fields. Saves over $300 USD in hardware.
A virtual COM port emulator creates a software-simulated serial port in Windows. PV-COM creates this port so applications expecting RS-232 serial data can receive it even when the scale is connected via USB. Solves compatibility issues between legacy scales and modern software.
PV-COM has a storage module that saves each weight reading to MySQL with timestamp and configurable fields. No programming required — configure connection parameters once and PV-COM logs every weighing event automatically.
PV-COM enables RS-232 and USB scales without official drivers to work on Windows 11, including brands like Torrey, CAS, Mettler Toledo, Dibal, Ohaus, Fairbanks, Dymo, Magellan, Moresco, Rochi and 200+ additional models.
An HID (Human Interface Device) driver lets Windows recognize a USB scale as an input device, similar to a keyboard. PV-COM acts as an HID driver for USB scales not natively recognized by Windows, such as some Dymo, Mettler Toledo and other weighing brands.
