TSC 258238-001 USB to RS232 Adapter
Overview
The TSC 258238-001 is a USB-to-RS232 serial adapter designed to bridge modern USB infrastructure with legacy serial-based TSC thermal printers. This adapter solves a specific integration problem: when your warehouse labeling system, point-of-sale terminal, or warehouse management software still communicates via RS232 serial protocol, but your host computer or PLC only has USB ports. The 258238-001 translates USB signaling into standard RS232 serial frames — no driver installation required for basic serial terminal emulation on most operating systems.
Compatibility
This adapter works with TSC thermal transfer and direct thermal printer models configured for RS232 serial input. Common deployment scenarios include TSC M-series and T-series printers in warehouse cross-dock, shipping, and label-on-demand environments where legacy host systems or barcode data collection devices communicate via 9-pin D-sub serial connectors. Verify your TSC printer's manual for RS232 pinout and baud rate settings (typically 9600 bps, 8 data bits, no parity, 1 stop bit) before connecting.
Installation Notes
Connection is straightforward: plug the USB side into a host computer or powered USB hub, and connect the RS232 side to the printer's serial port using a standard 9-pin D-sub cable. No external power supply is required — the adapter draws power from the USB port. Test serial communication at the OS level (Device Manager on Windows, dmesg on Linux) to confirm port enumeration before deploying into production. If your printer firmware requires specific serial protocol settings (flow control, parity), those must be configured on the printer itself — this adapter passes the signal through without modification.
