These cards can be installed in any 5-volt PCI-bus computer that can accommodate "long" cards and are designed to provide effective communication on long communication lines in noisy environments. The data lines are opto-isolated from the computer and from each other to assure communication even when large common mode noise and voltages are superimposed. Type 16550 UARTs are used. These include a 16-byte transmit/receive FIFO buffer to insure against lost data in multitasking operating systems. All ports are independently addressable and an on-board crystal-controlled oscillator permits precise selection of baud rates up to 115,200 baud or, by changing a jumper, up to 460,800 baud.
Input/Output connections are via a 37-pin D connector on the card mounting bracket. The standard configuration also includes 18-inch long (457 mm) breakout cables for two and four port connections.
EIA 485 models support half-duplex communications with a two-wire cable connection. Also, in EIA 485 communications under Windows programs, the driver must be enabled and disabled as needed to allow multiple communication ports to share the same two-wire cable. The PCI-ICM485/4 card controls the driver automatically. Under this automatic control, the driver is enabled when data are ready to be transmitted and then, when transmission is complete, the driver remains enabled for one additional character's transmission time and then is disabled. Correspondingly, the receiver is always enabled except during transmission time and then re-enabled when transmission is complete.
A transmission line should be terminated in its characteristic impedance at the receiving end. Jumpers are provided for each port to select termination impedances on the lines.
When the card is first installed, Windows will detect it as new hardware and assign it an IRQ number and base address. There are no switches to set or base addresses to assign, making it easy to use. From this point on, the card behaves as standard COM ports starting at COM 5. You cannot set or change the card’s base address, you can only determine what the system has assigned. The PCI Bus supports 64K of I/O address space so your card's address may be located anywhere in the 0000 to FFFF range.
