4-Port RS-485 | PCIe Mini Card
TC-003-01
TC-003-01 is a rugged, high performance full size PCIe Mini Card which adds 4 independent half-duplex RS-485 serial ports to any embedded system or computer. Supporting baud rates up to 12Mbit/s and large 2 kilobyte transmit and receive buffers on each channel, this card is designed for reliable, high speed serial communication. Each channel includes a termination resistor for use with long cables or high speed communication busses, to ensure proper cable termination. Local echo provides bus collision detection during data transmission, and automatic transceiver turn around (ATTA) automatically enables/disables the bus drivers without the need for flow control.
TC-003-01 exceeds TIA/EIA-485 electrical specifications, utilizing one of the highest performance differential transceivers on the market. Robust ESD protection on all communication signals and extended common mode voltage range of ±15V ensures operation in harsh electrical environments. The Molex Micro-Lock Plus connector provides the highest reliability in cable retention and sets the TC-003-01 apart from other products in its class. An audible positive-locking connector and large metal solder tabs ensure a solid, reliable connection in high vibration and industrial temperature environments.
Designed with a high performance USB bridge from FTDI, the TC-003-01 can integrate into any embedded system with minimal software or firmware effort. Plug-and-Play drivers for both Windows and Linux are available and supported by FTDI, the proven industry standard for USB-Serial bridge chipsets.
