Introduction

The PCI Local Bus is a high-performance bus that provides a processor-independent data path between the CPU and high-speed peripherals. PCI is a robust interconnection mechanism

designed specifically to accommodate multiple high performance peripherals for serial communication, SCSI, LAN, etc.

Advantech serial communication cards leverages the “Plug & Play“ capability defined in the PCI 2.1/2.2 bus specification, and are available with up to 8 ports. The board requires

only one PCI slot within the personal computer and provides independent serial channels. All channels are addressed in a continuous 32 byte I/O block for simplified software access.

And, all channels may also share one PCI interrupt. An interrupt status register is available for determining the interrupt source.

The Advantech PCI communication cards come with standard 16PCI954/16PCI952 UARTs containing 128 byte FIFOs which are available as an option. These upgraded FIFOs greatly

reduce CPU overhead and are an ideal choice for demanding multi-tasking environments.

The Advantech PCI communication cards are available with optical isolation up to 3000 V

DC.

This protects your PC and equipment against damages from ground loops, which increases

system reliability in harsh environments. To further increase reliability, the boards offers surge protection; protecting your system from abrupt high voltage surges (up to 3000 V

such as those caused by lightning during thunderstorms.

16PCI954/16PCI952 UART

The 16PCI954/16PCI952 is a high performance Quad UART with an on-chip PCI interface. Targeted at PCI-based serial and parallel expansion cards, PCI-architecture computer systems

and embedded applications, the 16PCI954/16PC1952 integrates a PCI bus interface together with four 16C950 high performance UARTs, a bi-directional parallel port and a local bus

bridge function. This single-chip solution replaces five or more integrated circuits used in today's products, giving performance, cost and size advantages to new designs.

Quick Troubleshooting

Advantech provides easy-to-use analysis tools and utilities that allows you to monitor or log data between two communicating devices, and help you acquire the data within a friendly

user interface. Diagnostic functions make the installation process trouble free.

An RS-485 Network with Automatic Data Flow Control Using RS-232 Software

The RS-485 mode automatically senses the direction of incoming data and switches its transmission direction accordingly. The feature makes your network look and act just like

an RS-232 network. Application software written for half duplex RS-232 can be used without modification. Moreover, you can simply and quickly build an RS-485 network with just

two wires.
