Isolated PCI Express Serial Communication Family with Speeds up to 3 Mbps
Page 1 of 1
A new family of isolated PCI Express serial communication cards features a selection of 4 or 2 ports of isolated, software selectable, RS-232, RS-422 and RS-485 serial protocols. 2 kV isolation is provided between channels and between the PC and bus lines on ALL signals. The cards from Acces I/O Products feature a x1 lane PCI Express connector, which can be used in any available x1, x2, x4, x8, x12, or x16 PCI Express expansion slot. The PCIe-ICM product line has been designed for use in retail, hospitality, automation, gaming, shipboard and defense industries along with applications such as point of sale systems and kiosk design.
The PCIe-ICM cards were designed using type 16C950 UARTS and use 128-byte transmit/receive FIFO buffers to decrease CPU loading and protect against lost data in multitasking systems. New systems can continue to use legacy serial peripherals, yet benefit from the use of the high-performance PCI Express bus. The cards are fully software compatible with current PCI 16550 type UART applications and allow for users to maintain backward compatibility.
The PCIe-ICM Series is especially useful in applications where high common-mode external voltages are present. Isolation is required to guard electronics from transient voltage spikes and offers greater common-mode noise rejection in electrically noisy surroundings containing industrial machinery and inductive loads. In addition to protecting industrial applications from accidental contact with high external voltages, the isolation provided eliminates troublesome ground loops.
A complete driver support package is provided including an easy-to-use Windows terminal program for testing your COM ports. This simplifies the verification of proper COM port operation. The cards install as standard COM ports in all operating systems including DOS, Linux (including Mac OS X) and Windows 2000/XP/2003/Vista/7.
