Epson CEPS-011 DB9 Null Modem Cable 10ft
Overview
The Epson CEPS-011 is a 10-foot null modem cable with female DB9 connectors on both ends. This cable bridges serial communication between Epson printers and host systems, control devices, or peripherals that require null modem configuration — the transmit and receive lines are crossed, allowing direct device-to-device connection without an additional adapter. Deploy this when you need reliable serial handshaking in warehouse, retail, or logistics environments where label printers must talk to POS systems, warehouse management software, or older automation controllers over standard serial ports.
Compatibility
The CEPS-011 works with Epson printer models and systems equipped with DB9 serial ports that support null modem pinout configuration. Common integrations include legacy point-of-sale terminals, label printers, and industrial printing systems using serial RS-232 communication. If your device requires DB25 connectors or uses RJ-45 Ethernet instead, this cable will not work — verify your hardware uses female DB9 ports before ordering.
Installation Notes
Cable length of 10 feet covers most counter-top and rack-mounted printer setups without excessive slack or tension. Null modem configuration (lines 2 and 3 crossed) is factory-built — no field re-termination required. Ensure both connected devices have DB9 female ports; if one end is male, use a gender changer adapter. Keep cable away from high-voltage power lines and electromagnetic noise sources to maintain signal integrity on long runs.
