National Instruments SH68-8DB9 Serial Cable

The National Instruments SH68-8DB9 (Part Number: 197545-01) is a 1-meter serial cable used to connect various devices to PXI and PCI-based serial interface cards. In order to enable simultaneous connections to several serial devices, this cable is specifically made to convert a 68-pin VHDCI (Very High-Density Cable Interconnect) connector into eight distinct 9-pin DB-9 (D-Subminiature) connectors. This cable is frequently utilized in systems that need RS232 connection. It is perfect for connecting to gadgets including GPIB-controlled equipment, LCDs, and barcode scanners.

The SH68-8DB9 is a useful add-on for industrial automation and CompactPCI or PXI systems since it is completely compatible with National Instruments serial interface cards, such as the PXI-8421 Serial Interface Card. It offers effective access to numerous serial communication channels from a single connection point by segmenting the 68-pin VHDCI connector into eight groups of nine channels.

In order to ensure reliable data transmission and lower the possibility of signal interference, the cable is insulated to prevent electrical noise. For systems requiring high-reliability communication using serial protocols, the SH68-8DB9 type is the recommended option because to its improved performance when compared to unshielded cables. Because of its one-meter length, installation flexibility is offered while signal integrity is preserved.

Connectivity-wise, this cable is also flexible, with eight 9-pin Male DB-9 connections on one end and a 68-pin Male VHDCI connector on the other, providing numerous ways to connect to various peripherals or devices. In applications like industrial automation, testing settings, and communication systems where multiple RS232-based devices must operate simultaneously, the SH68-8DB9 connection is commonly used.
