Citizen TA66814-0M SEH Ethernet Board

Overview

The TA66814-0M is an SEH Ethernet interface board that adds network connectivity to Citizen receipt printers in the CTS310, CTS2000, and CTS4000 series. This board solves the deployment constraint of printers that require Ethernet rather than USB or serial connectivity — necessary when integrating across distributed POS terminals or warehouse systems that lack local USB reach to a central server. Install this board directly into the printer to enable remote print jobs over standard Ethernet without additional external adapters.

Compatibility

This board is compatible exclusively with Citizen CTS310, CTS2000, CTS4000, and CD-S500 thermal receipt printer models. Verify your printer model before ordering — this board will not work with other printer families or non-compatible variants. The board installs as an internal interface card, so confirm your printer's internal slot availability and model revision with the printer documentation or your systems administrator before purchase.

Installation Notes

This is an internal interface board installation. Power down the printer completely before opening the enclosure. Install the board into the designated interface slot on the printer's motherboard, ensuring the connector is fully seated. After installation, reconnect power and configure the printer's network settings through the printer's menu system or web interface. Consult the printer's service manual for specific slot location and connector orientation to avoid damage to the board or printer circuitry.
