Low-profile serial-port PCI cards

26 November 2008 Computer/Embedded Technology

Advantech’s new RS232/422/485 low-profile PCI communication cards are compatible with the PCI 2.2 bus specification for universal connectivity.

The PCI-1604UP provides two independent RS232 ports, while the PCI-1602UP has two RS422/485 ports. The PCI-1610UP and PCI-1610AUP provide four RS232 ports. To enable enhanced system performance, all cards allow transmission speeds up to 921,6 Kbps. For increased reliability, they offer EFT surge protection, protecting the system from abrupt high voltages up to 2 500 V d.c. High-performance UARTs with 128 Byte FIFOs reduce the CPU load, making the cards suitable for multitasking environments.

The cards follow the Low Profile PCI MD1 standard. This standard has the same protocol and electronic definition as standard PCI, but the Low Profile PCI standard is smaller. Thus, the cards are suitable for embedded systems, and size-constrained environments. Moreover, all cards are equipped with a universal PCI connector, which allows support for traditional systems with 5 V signalling or newer systems with 3,3 V signalling.

Advantech also provides ICOM Tools, a convenient utility to help test the PCI cards’ performance by analysing port status. ICOM Tools’ menu commands and toolbar buttons act as a PC-based data scope that sets a trigger condition, captures the communication data and monitors the signal status.
