1 Ver..0 RS-A/ Serial I/O Board with Isolation for PCI ch ch COM-PD(PCI)H This board is a PCI bus interface board for performing RS-A/ serial communications with external devices. The <> has two RS-A/ serial ports per The <COM-PD(PCI)H> has four RS-A/ serial ports per You can use the standard COM driver software (COM Setup Disk) supplied with the board to access the serial ports as standard Windows or Linux COM ports. The board is backward compatible with the CTEC COM-PD(PCI) The can therefore replace the COM-PD(PCI) in an existing system. The, color, and design of a product may be changed without a preliminary announcement. Features - RS-A/ serial communication ports - The communication lines for each channel are electrically isolated from each other and from the PC. - Maximum communication speed =,00bps. - The baud rate can be set independently for each channel, by software. - Each channel is equipped with separate -byte FIFO buffers for transmit and receive. - A maximum of boards can be installed as configured in the range COM - COM. - Driver software is supplied to allow the serial ports to be used as standard Windows or Linux COM ports. - The data transfer mode (full duplex or half duplex) can be set by a switch. - The board includes a 00 terminating resistor required for multi-drop (party line) connections. The resistor for each channel can be inserted into the signal line by a switch. - Surge protection is provided for each RS-A/ signal line.

2 Ver..0 Support Software You should use CTEC support software according to your purpose and development environment. Standard COM Driver Software COM Setup Disk COM Setup Disk (Bundled) The purpose of this software is to allow the CTEC serial communication boards to be used under Windows or Linux in the same way as the standard COM ports on the PC. By installing additional boards, you can use COM ports in the range COM to COM. The boards can be used for all types of serial communications such as for remote access service (RAS) and uninterruptible power supply (UPS) applications. Under Windows, the serial ports can be accessed using the standard Win API communication routines (CreateFile( ), WriteFile( ), ReadFile( ), and SetCommState( ), etc.) The serial ports are also compatible with the Visual Basic communication control (MSComm). Under Linux, the serial ports are compatible with the operating system's standard tty driver. The standard routines including open( ), close( ), read( ), write( ) are supported. < Operating environment > OS Windows XP, 000, NT, Me,, etc.. The maximum number of COM ports able to be used depends on the configuration of your OS. Driver library API-PAC(W) (Available for downloading (free of charge) from the CTEC web site.) API-PAC(W) is the library software that provides the commands for CTEC hardware products in the form of Windows standard Win API functions (DLL). It makes it easy to create high-speed application software taking advantage of the CTEC hardware using various programming languages that support Win API functions, such as Visual Basic and Visual C/C++. It can also be used by the installed diagnosis program to check hardware operations. CTEC provides download services to supply the updated drivers and differential files. For details, visit the CTEC's Web site. < Operating environment > OS Windows XP, 000, NT, Me,, etc.. Adaptation language Visual C/C++, Visual Basic, Delphi, Builder, etc.. OthersEach piece of library software requires 0 megabytes of free hard disk space. This library provides local routines that are specific to CTEC (SioOpen( ), SioWrite( ), SioRead( ), SioStatus( ), etc.). These are not compatible with the standard Win API communication routines (CreateFile( ) and WriteFile( ), etc.).

For CTS, even numbered pins are - and odd numbered pins are +. This is the opposite of the other signals, but is not a misprint. When using a COM-PD(PCI)H, an alternative to connecting an external device directly to the connector on the board is to use a connection conversion cable. Use a PCE/PS connection conversion cable (purchased separately) to connect to external devices after dividing into four -pin D-SUB male connector channels. - Cable -conductor shielded cable Cable length : 0mm Conductor size : AWG# -pin D-SUB, male connector Thumb screw : UNC #-0 (inch screw) CH CH CH CH RTS- RTS+ CTS+ CTS- RTS- RTS+ CH.

However, the frame of each connector is connected to the shielding. This means that the cable shielding is connected to the body of the PC via the frame of the interface connector. Note that the option cable is not a twisted-pair cable.
