Four-port RS232 PCI communication card

16 June 2004 Computer/Embedded Technology

A 4-port RS232/422/485 PCI communication card is available from ProMicro that is compatible with the PCI 2.1 bus specification. The PCI-1610A/B provides four optional surge protection ports to protect the system against surges up to 2500 V d.c.

The card provides transmission speeds of up to 921,6 Kbps, and high performance 16PC1954 UARTs with a 128-byte FIFO reduce the CPU load, making the card reliable and ideally suited for multitasking environments. A convenient utility program is included allowing users to test the card's performance by analysing the port's status, while easy to use menu commands and toolbar buttons simplify operation.

ICOM tools act as a PC-based data scope allowing the user to set a trigger condition, capture the communication data and monitor the signal status.

The communication card maps to just 16 KB of system memory and the user can choose between six addresses from C8000 to DC000. Various IRQ options are available and LEDs monitor the TxD/RxD status of all ports. The card is capable of linking to peripherals up to 1,2 m from the controller.
