This chapter provides information you should know before using the product.
About the Board
This product is a PCI bus-supported board designed for extending RS-422A/485 compatible serial
communication functionality on your PC.
The < COM-2PD(PCI)H > has two RS-422A/485 communication ports.
The < COM-4PD(PCI)H > has four RS-422A/485 communication ports.
Higher noise-resistant models with isolation between a PC and bus line as well as a surge protection
circuit for communication ports. With a 128byte built-in FIFO buffer for transmission and reception of
each channel, the product supports a baud rate of up to 921,600bps. It also comes with a Windows/Linux
driver, which allows boards to be used as OS-standard COM ports.
This product supports CONTEC-defined driver library "API-PAC(W32)" that provide local routines.
The COM-2PD/4PD(PCI)H boards are backward compatible with the CONTEC COM-2PD/4PD(PCI)
boards. The COM-xPD(PCI)H can therefore replace the COM-xPD(PCI) in an existing system.
Features
- Max. 921,600bps RS-422A/485 Serial Communication
The < COM-2PD(PCI)H > has two RS-422A/485-standard serial ports.
The < COM-4PD(PCI)H > has four RS-422A/485-standard serial ports.
Baud rates from 2 to 921,600bps can be set. When using the bundled "Standard COM Driver Software"
and "Driver library API-PAC(W32)", baud rates from 15 to 921,600bps can be set.
- Possibly used as Windows, Linux-standard COM ports, using the bundled driver library
Comes with a driver software that allows the products to be used under Windows / Linux in the same
way as COM ports on the PC. Under Windows, the product supports the OS-standard Win32 API
communication function as well as Visual Basic MSComm. Under Linux, OS-standard tty driver's
standard-function can be used. In addition, supplies a diagnostic program to confirm hardware operation
and to perform a communication test with equipment.
- Isolation between channels and between PCs, surge protection for all signal lines
The channels are electrically isolated from each other and from the PC.
As isolation is provided between channels as well as isolation of the bus, this prevents electrical noise
between channels as well as between the PC and external circuits. As surge protection is provided on all
signal lines, you can safely use the boards in environments where you are concerned about surges
causing incorrect operation or damage to the PC.
- Max. 16 boards can be installed as configured in the range COM1 - COM256.
Up to 16 boards can be mounted on a single PC.
COM1 - COM256 can be set using the device manager.
COM-2PD(PCI)H, COM-4PD(PCI)H
