Advantech 4 Port RS232/422/485 PCI Card - Surge Protection and DB9 Cable
Dove Code: AQ1556-D9 |
Manufacturer: PCI-1612B/9-A


4-port RS-232/422/485 PCI Comm Card, featuring Surge Protection and also including DB9 cable.

The PCI-1612B9A is a 4-port RS-232/422/485 PCI communication card that is compatible with PCI 2.1 bus specifications and offers transmission speeds up to 921.6 kbps.

Including high-performance 16PCI954 UARTs with a 128-byte FIFO to reduce CPU load.
These components make your system more stable and reliable, making the PCI-1612 is especially suitable formultitasking environments.

To further increase reliability, the PCI-1612B9A offers EFT surge protection for high voltages up to 2,500 VDC.

Advantech also provides a convenient utility program called ICOM Tools to help test the PCI card performance by analyzing the port status.

The menu commands and toolbar buttons of ICOM Tools acts as a PC-based data scope that lets you set a trigger condition, capture the communications data and monitor the signal status.

ICOM Tools are applicable to all series of Advantech ICOM cards.
