Windows device driver information for ACCES PCI-COM485/4

It is a serial interface card. The PCI-COM485/4 is a four-port, asynchronous serial communications card designed for the use in PCI-Bus systems. The card may be installed in any 3.3V or 5V PCI or PCI-X slot. It is compatible with the universal PCI, 3.3 V and 5V. It supports the RS-485 multidrop networks. The features include the type 16550 UART with 16-byte FIFO buffers. The baud rates up to 460,800 baud. It has an automatic control of RS-485 driver under windows systems. It has a choice of I/O connection methods. It only requires one I/O slot which is a 9-pin D-sub connector. It has no base address or IRQ switches to set. The character length is 5, 6, 7 or 8 bits. The parity varies form even, odd or none. The stop intervals of the communication interface are 1, 1.5 or 2 bits.

The receiver input sensitivity is +200mV or -200mV, which is a differential input. The common mode rejection is +12V to -7V. The transmission output drive capability is 60Ma with thermal shutdown. Each independent port supports RS-485 balanced mode transmission/reception. Each port has the capability to add bias voltage. In addition, receiver networks at each end of the networks should be terminated to eliminate ringing. These cards support that need by means of jumpers on the card. The Type 16550 UARTs are used as the asynchronous communication elements. These include a 16-byte transmit/receive FIFO buffer to protect against lost data in multitasking systems while maintaining 100 percent compatibility with the original IBM port. There are no switches to set or base addresses to assign, making it easy to use. After installation, the card behaves as standard COM ports at COM 5, 6, 7, and 8. It is highly recommended you run a free registry scan for and ACCES PCI-COM485/4 errors before installing any driver updates.
