Epson CEPS-003G Serial Cable DB9-to-DB25 6ft

Overview

The Epson CEPS-003G is a 6-foot null modem serial cable that bridges DB9 female connectors to DB25 male connectors — a direct fit for legacy industrial printers, thermal label systems, and warehouse point-of-sale terminals that still rely on serial communication. Dark grey jacket provides standard abrasion resistance in high-touch warehouse and installation environments where cables run under desks, through conduit, or across dock floors. If your thermal printer or data terminal uses a DB9 interface but your control system or host device expects DB25, this cable eliminates the need for an adapter stack.

Compatibility

The CEPS-003G integrates with Epson thermal printers and compatible legacy serial devices requiring DB9-to-DB25 null modem pinout. Confirm connector gender (9-pin female on the printer side, 25-pin male on the host side) and signal compatibility with your specific equipment before deployment — not all serial devices use identical pinout conventions. Common deployments include Epson TM-series receipt printers, label printers in WMS-driven warehouses, and POS terminal connections where host systems use 25-pin serial ports.

Installation Notes

Verify serial signal levels (RS-232 standard) match both the printer and host device — mixed RS-232 and RS-485 equipment on the same cable can damage both ends. Keep the cable away from high-voltage AC power lines and induction sources (induction heating, welding equipment) in warehouse environments; shielding is standard but not military-grade. Test handshake signals (RTS, CTS, DSR) before relying on two-way data flow, as some devices disable flow control by default. The 6-foot length suits desktop-to-printer runs and short wall mounts — for longer runs (15+ feet), consider external RS-232 repeaters or active extension boxes to avoid signal degradation.
