It is an isolated four-port serial interface card. It is compatible with the universal PCI, PCI-X, 3.3V and 5V. It is optically isolated and a asynchronous serial communications. It has a choice of the EIA 422 or EIA 485 model. Type 16550 UARTs are used. 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. 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. They are usable at cable lengths up to 4000 feet.
Unless you update your drivers regularly you may face hardware performance issues.
To check your drivers you should manually verify every device on your system for driver updates
The I/O connection is a 37-pin DBM connector. The serial port is an external breakout cable that terminates in a female, 9-pin Sub-D connector for each port. Its character length is 5, 6, 7 and 8. 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. There are no switches to set or base addresses to assign, making it easy to use. 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. It is detected as a standard COM ports under windows. It is highly recommended you run a free registry scan for and ACCES PCI-ICM422/2 errors before installing any driver updates.
