Saelig Company Releases New USB Serial Converter

By DE Editors

Saelig Company, Inc. has released the new CE-USB, a USB-powered, USB2.0-to-RS232 adapter, packaged in a DB-9 form factor shell, that is designed to add a USB interface to legacy serial products without hardware or software redesign requirements.

The CE-USB simplifies legacy updates by replacing an industry-standard right-angle PCB-mount DB9 connector with a near-identical part, with the mechanical specifications of an AMP 745131-1. It uses the DB9’s same PCB pad pinout to allow immediate updates to older serial products without layout changes, while drawing no additional power from the embedded system, and just 35 mA from the USB port. Drivers are supplied for many operating systems,  including Windows, MacIntosh and Linux.

CE-USB’s device drivers allow it to appear to an operating system as an additional COM port, and sends 8-bit asynchronous serial data at selectable speeds between 300 and 921.6k bps. PC application software accesses the device as it would a physical COM port. Existing COM port applications can thus be used to transfer data via a PC’s USB port, with no software changes.

The CE-USB adapter is molded in black Valox resin and features a mini-USB connector similar to those used in cameras and other small devices. Because the CE-USB is integrated, only a USB cable is needed between the PC and the target system. Because the product is based on Silabs’ CP2102,  all RS-232 signals, including handshakes, are available. CE-USB’s UART interface consists of TX (transmit) and RX (receive) serial data signals as well as the RTS, CTS, DSR, DTR, DCD, and RI control signals. The UART supports RTS/CTS, DSR/DTR and X-On/X-Off handshaking, and the serial port configures as an RS-232C DTE (Data Terminal Equipment).

Units are available in North America from Saelig starting at $25.99.
