Citizen CL-S400DTBTUBKR Roll Holder 120V Bluetooth Serial USB
Overview
The Citizen CL-S400DTBTUBKR is a powered roll holder designed for the Citizen CL-S400 thermal printer. It supplies 120V power to the printer unit and includes integrated Bluetooth, serial (RS-232), and USB connectivity — solving the installation challenge of powering and communicating with the CL-S400 in retail, warehouse, or logistics environments where roll media must remain mounted and accessible. This configuration is purpose-built for continuous roll operation without requiring a separate external power supply.
Compatibility
The CL-S400DTBTUBKR roll holder is designed exclusively for the Citizen CL-S400 thermal printer series. Verify your printer model before ordering — this holder will not work with other Citizen printer families or competitive models. The 120V AC input and integrated communication ports (Bluetooth, serial, USB) are matched to CL-S400 specifications only.
Installation Notes
The roll holder mounts the media roll directly and supplies power through a dedicated connector to the printer base. Confirm 120V AC availability at the installation site and ensure the outlet is grounded. The serial and USB ports allow simultaneous connectivity — configure your host application to use one primary interface (typically USB for new deployments, serial for legacy system integration). Bluetooth pairing requires the printer to be powered and within range of your control device. Consult the CL-S400 user manual for specific wiring and connector pinout details.
