RS-232 UB-S01

Epson RS-232 UB-S01 — Serial Interface Card for Existing Printers

The Epson RS-232 UB-S01 is a serial interface card designed for compatible Epson receipt printers. Important: this card is already fitted as standard in all Epson printers sold with RS-232 connectivity. Order this card only when you need to swap the interface on a printer you already own — not when buying a new RS-232 printer.

Who needs this?

This card is for businesses running an older point-of-sale system or specialist software that talks to the printer over a serial connection. Some cafés, restaurants, and retail setups still rely on RS-232-based POS software where a USB or Ethernet connection simply will not work as a direct replacement.

Check these things before ordering

• ·Confirm which interface card is currently fitted in your printer.
• ·Check the connection requirements of your POS software or till system.
• ·Most current Epson printers already ship with an RS-232 card installed — you only need this if you are switching from a different interface type.

Not sure whether the RS-232 UB-S01 fits your setup? Get in touch with Vaivatta before ordering and we will confirm the right interface for your till system — no guesswork, no wasted trips to the post office.

Installation

Swapping an interface card is a technical job. If you have not done it on an Epson printer before, we recommend letting Vaivatta handle the installation. We fit the card and confirm the printer is talking to your till system correctly before we hand it back — so your trading day is not lost to a wiring puzzle.
