PCL-740  1-port RS232/422/485/I-loop- ISA Bus

The PCL-740 offers a versatile range of high speed interfacing options.
You can switch its single port between the popular RS-232, long distance RS-422, multi-drop RS-485, or noise-resistant current-loop.
The card’s 16C550 UART has an on-chip 16-byte FIFO buffer for faster and more reliable communication, especially under Windows.
The card has two 16C550 UARTs with on-chip 16-byte FIFO buffers. The UARTs buffer data into 16-byte packets before sending it to the bus. This drastically reduces CPU load and avoids data loss when the system is busy and cannot process the interrupt quickly.
These FIFO buffers make the PCL-741 especially suitable for high speed serial I/O under Windows.
Onboard optical isolators protect your PC and equipment against damage from ground loops, increasing system reliability in harsh environments.

CAN Bus Cards

CAN Communication Cards
Advantech CAN communication card series are the special purpose communication card that offers the connectivity of the Controller Area Network (CAN) to your PC.
With its built-in CAN controllers, the Advantech CAN communication card series provide bus arbitration and error detection with an automatic transmission repeat function.
This drastically reduces the chance of data loss and ensures system reliability.
The on-board CAN controllers are located at different positions in the memory, and you can run both CAN controllers independently at the same time.
