Description
ESS Technologies FM-3623-11 V7.0 56K PCI Modem Card ESS2838 Winmodem Fax Data
The ESS Technologies FM-3623-11 is a V7.0 56K internal PCI dial-up modem card built around ESS Technologies' own ES2838 (ESS2838) controller chipset. It connects to a standard telephone line via RJ-11 and supports data and fax communication at speeds up to 56 Kbps. As a software-based winmodem, it offloads modem processing to the host CPU, making it a lightweight and low-cost solution for dial-up connectivity in desktop PCs. The board marking MPE28385PS is visible on the PCB.

Applications
The ESS FM-3623-11 is a mid-to-late 1990s era PCI dial-up modem card, produced during the period when 56K V.90 became the standard for consumer and small-business internet access. ESS Technologies was a major OEM chipset supplier during this era — their ES2838 and related chips were found in a large number of value-priced modems sold under dozens of brand names. These cards were standard equipment in Windows 98, ME, 2000, and XP desktop PCs for connecting to dial-up ISPs, fax machines, and remote-access servers. Today they are used primarily in legacy industrial, POS, and SCADA systems that still rely on dial-up or analog telephone line communication, as well as in vintage PC restoration projects. Drivers are available from ESS Technologies for Windows platforms.
This ESS Technologies FM-3623-11 V7.0 56K PCI modem card has been inspected and is in good condition. It was pulled from a working environment where it was in active use. The card shows normal light wear consistent with normal service life — the PCB is clean, the bracket is straight, and the RJ-11 ports are intact.
