Description

The ideal solution for adding serial connectivity to a wide variety of desktop server and embedded systems Quatech UniversalPCI (low profile) serial boards are the most reliable in the industry.These UPCI serial boards use a Universal PCI connector compatible with both the 3.3V and 5V signaling. They are designed on the smallest MD1 Low Profile PCI footprint but come with both a full size ORB for standard systems and a smaller ORB for use in LowProfile backplanes to fit even 2U racks without riser cards. Available in 1 2 4 and 8 port counts RS-232 or RS-422/485 (1 and 2 ports only). Standard height Quatech Serial PCI Boards are also available from Quatech. Quatech Universal PCI (low profile)boards provide truly universal connectivity enabling a single product to be used to implement systems with dramatically different resource requirements. The Low Profile PCI footprint was designed to provide greater flexibility for embedded systemsthin-clients and desktop and server environments. The boards are mechanically similar to standard PCI boards but use a shorter board and a different mounting bracket. They are designed to fit into systems as low as 3.350 without using riser cards. Theboards are built on 32-bit addressing and can be used in standard PCI backplanes or with specialized Low Profile PCI brackets. Quatech's boards are built using the smallest (MD1) Low Profile board specification which allows them to be used in even thesmallest size systems without riser cards. PCI 2.3 requires that all plug-in cards support 3.3V signaling. However many systems still use 5V signaling. Quatech UniversalPCI (Low Profile) boards are designed to accommodate both system types by using aUniversal PCI connector compatible with both 3.3V and 5V signaling. They are also compatible with both 32-bit and 64-bit systems. This means that they can be used with current equipment and will not need to be replaced as systems are upgraded. It alsomeans that a single serial board solution can be u

Product review & video

today you'll learn about rs-232 it's a phrase you may hear fairly regularly in industry especially by the older guys hopefully this video will clear some things up for you [Music] before we get into today's video if you love our videos be sure to click the like button below and make sure to click Subscribe and the bell to receive notifications of new real Parrs videos this way you never miss another one what exactly is rs-232 first and foremost it is a form of serial data transmission or simply put it is a form of communication most people simply called it a serial connection at one time it was the most used form of data transmission you'll probably recognize the standard nine pin db9 cable simply put rs-232 transmit signals using a positive voltage for a binary zero and a negative voltage for a binary one but what do the PLC's use rs-232 for PLC's use rs-232 to talk to other modules or
