Windows device driver information for ACCES PCI-COM-2S

Among the many device by Acces, ACCES PCI-COM-2S is a PCI card that is connected to a bus. This enables a user to connect components to the computer's processor. Users may see this connections among their other computer hardware such as hard disks, memory, sound systems, video systems and a lot more. The very usage of this device is to construct parts that are more interchangeable. These devices can just be plugged or unplugged if the user may want to upgrade or downgrade their computer hardware. It was the early ninety’s when Intel first introduced the first PCI bus or what is known as the Peripheral Component Interconnect bus. This stands as the hybrid of sorts between ISA and VL Bus. The PCI bus gives admittance to system memory for connected devices. It will need a bridge so as to connect to the front side bus and thus to the CPU or the central processing unit for it to operate and function properly. This physical connection actually connects the processor to most of the other components in the user’s computer. The connections included are the main memory or RAM, hard drives and the PCI slots. ACCES PCI-COM-2S contains one of the two kinds of dual ports namely PCI-COM2S and PCI-422/485-2. These devices are both asynchronous serial communications cards and are used in PCI Bus computers. The dimension of this PCI card is 6.5 inches long which may built in any 3.3V or 5V PCI or PCI-X slot.

Outdated Drivers?

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

Each of outstandingly designed port caters to RS-422 and RS-485 balanced mode transmission and also reception. While on PCI-COM2S device type, it uses a RS-232 single-ended transmission and or reception as well. Furthermore, these ports are powered to add bias voltage to the device. It also makes use of type 16550 UARTs for asynchronous communication elements. As such, a 16-byte transmit and or receive FIFO buffer is used in order to shield the device and its function against lost data while doing multitasking systems as well as maintaining one hundred percent compatibility with the original IBM serial port. Another notable feature of this card is that it has built-in crystal oscillators situated on the card. It has an exact baud rate capability which reaches up to 115,200. It is also said that higher speeds can be reachd with levels that are up to 460,800 baud. The oscillator’s drivers/receivers requires connections such as RS-485 & RS-422 which are type 75ALS180. These connections are capable of driving long communication lines at high baud rates. It is highly recommended you run a free registry scan for and ACCES PCI-COM-2S errors before installing any driver updates.
