Product information

Description

The Interface Card for Citizen CT-S600 / CT-S800 printers — Serial (TZ66801-0M) is an add-on module that provides an RS-232 serial communication port for compatible Citizen receipt printers. Designed for in-field installation into the printer expansion slot, this card enables reliable wired connections to point-of-sale systems, scales, or other legacy equipment that require a standard serial interface. The module maintains factory fit and compatibility with the CT-S600 and CT-S800 mechanical and electrical configurations.

Advantages

This serial interface card delivers stable RS-232 communication with predictable latency and broad device compatibility. Installation into the printer expansion slot preserves the printer’s original form factor while adding a durable, wired connection option. The card supports common serial settings to simplify integration with POS software and peripherals and reduces dependency on USB or network adapters for legacy integrations.

Suitable for

Retail point-of-sale systems requiring RS-232 connectivity
Hospitality environments integrating receipt printers with legacy terminals or scales
Industrial or kiosk applications where wired, low-latency communication is preferred
Environments that need a direct serial link for diagnostic or control interfaces

Key specifications

Interface type: RS-232 serial port
Compatibility: Designed for Citizen CT-S600 and CT-S800 printers
Installation: Fits printer expansion slot for in-field installation
Connection: Standard DB9 or equivalent serial connector on card (cable-dependent)
Electrical characteristics: TTL/RS-232 level compatible with standard serial peripherals

How to use

Power off the Citizen CT-S600 or CT-S800 printer and open the expansion slot cover following the manufacturer’s service instructions. Insert the serial interface card into the expansion slot, ensuring a secure seating and fastening according to the printer’s installation guide. Reattach any covers and power on the printer. Configure the printer’s interface settings via its setup menu or connected POS software to match the serial parameters of the host device (baud rate, parity, data bits, stop bits, flow control). Connect the serial cable between the printer and the host device and verify communication by printing a test receipt or using diagnostic commands.

Usage recommendations

Use shielded serial cables and proper grounding where possible to reduce electrical noise and prevent data errors. Match serial parameters on both devices before attempting data exchange. For long cable runs or electrically noisy environments, consider using shorter cables or placing equipment to minimize interference. Refer to Citizen printer documentation for detailed installation steps and safety precautions.
