EXC-4000PCIe/xx card & M4KSerial module
*** Not recommended for new designs *** click here for new designs
The EXC-4000PCIe/xx card for the PCI Express bus supports up to sixteen Serial channels using the M4KSerialPlus module. This module supports up to four independent channels of serial communications, each of which can be selected as RS-485, RS-422 or RS-232 and has a programmable baud rate of up to 10Mbps. The module operates independently of the host computer, reducing the need for host intervention.
The M4KSerialPlus module is based on the Exar XR16M570 Universal Asynchronous Receiver/Transmitter (UART). The device is compatible to industry standard 16550 UARTs. Each of the M4KSerialPlus’s four channels contains a transmit FIFO capable of holding up to 16384 bytes and a receive FIFO capable of holding either 16384 receive bytes or 5460 bytes with a 32-bit Time Tag associated with each byte. These large buffers allow application code to transfer large quantities of data with a single non-blocking subroutine call. The 32-bit Time Tag on receive channels is very useful for synchronizing serial data with data from other modules on the 4000 board or on other interface boards. Each channel has a programmable baud rate of up to 10 Mbps and can be configured as RS-232, RS-422 or RS-485.
The EXC-4000PCIe/xx is supplied with C drivers, including source code. Mating connector provided for I/O connection.
Please see multi protocol 4000 modules for additional information on protocols that can be added to this card.
NOTE: The M4KSerial module is now a Legacy product. All new projects should use the M4KSerialPlus module (these modules are not compatible) Click here for more details
