National Instruments PCI-485/2 Serial Interface

The PCI-485/2 (Part number: 777641-02) is a double port, non-concurrent serial communication cards intended for use in PCI-Bus PCs. They are 6.5 inches (165 mm) long and might be introduced in slots for PCI-Z, 5V PCI or 3.3. Every free port backings RS-485 adjusted mode transmission/gathering, and on the single-ended transmission/gathering too. Each port of the PCI-485/2 can include bias voltage. In this model, to guarantee the communication the RS-485 should offer a bias voltage required by one transmitter in the framework with the goal to offer a known "zero" state when all transmitters are OFF. Additionally, recipient communication at each end of the system ought to be ended to dispense with ringing. The PCI-485/2 bolsters these alternatives by methods for jumpers on the card.

In the PCI-485/2, 16550 UARTs types are utilized as the offbeat communication components. A 16-byte transmit/receiver FIFO buffer is incorporated in this instrument with the objective to ensure against lost information in multitasking frameworks while keeping up 100 percent similarity with the first IBM serial port. In this instrument, users will find a crystal oscillator situated on the card that will allow exact baud rate ability superior to 115,200. The greatest baud rates on the NI PCI-485/2 are superior to 460,800 baud and are accomplished by changing a jumper on the card. The driver/receivers utilized, type 75ALS180, are fit for driving greatly long communication lines at high baud rates. If there should arise an event of trouble between the communication, the driver/receivers feature warm shutdown. When the card is first introduced, the working framework ought to consequently identify and arrange the two COM ports for prompt use.

PCI-485/2 Obsolete Status has been announced by National Instruments, but will still be available for purchase and repairs by Apex Waves.
