The National Instruments PCI-8432/2 is a robust two-port RS232 serial interface designed for critical applications requiring reliable communication. With an isolated PCI architecture, this interface safeguards the connected PC and devices against potential damage from high voltage surges or spikes on communication lines. The PCI-8432/2 utilizes Data Terminal Equipment (DTE) standards, making it compatible with a wide range of computing devices and modems for optimal data transmission. This device features a maximum baud rate of 1 Mbps and connects via DB-9 male connectors, ensuring ease of integration into existing systems. Each of its two serial ports operates independently, allowing for versatile device communication even under networked configurations, such as those utilizing a serial Ethernet interface. This feature extends the distance limitations typically associated with RS-232 connections. The PCI-8432/2 has a power requirement of +5 VDC and draws 380 mA, while its compact dimensions of 4.2 in. x 6.9 in. and lightweight design (0.22 lb) facilitate straightforward installation. The device is supported by the NI-Serial software driver. While classified as mature, the PCI-8432/2 remains available for purchase and repair services through Apex Waves. Users can access the user manual and maintenance documentation for comprehensive support. Please contact a sales representative for pricing information.
