The Brainboxes PM-120 is a PCMCIA Type II card that provides a single RS422/485 serial communication port, designed to enhance serial connectivity for laptops and other devices equipped with PCMCIA slots. It features a 128-byte transmit (Tx) FIFO and a 128-byte receive (Rx) FIFO, utilizing a Brainboxes 16PCI950+ UART that is backward compatible with 16750, 16550, and 16450 standards, while also supporting an enhanced 950 mode. This card supports data transfer rates of up to 921,600 baud, with line drivers capable of 1Mbit/s, ensuring solid performance. The PM-120 includes a detachable, fully wired, molded cable with a 9-pin male (DB9) connector for external serial devices. For electrical protection, the card incorporates on-board Zener diodes and transient spike protection, safeguarding against noise and electrical surges. Its construction involves a 4-layer Printed Circuit Board (PCB) for enhanced signal integrity and EMC shielding. The PCMCIA card is compliant with the PC Card Standard-February 1995. ### Technical Specifications * **Host Interface:** PCMCIA (Personal Computer Memory Card International Association) Type II
