INTENDED PURPOSE OF THE BOARD
The board
APCI-7501
provides the personal computer (PC) with a 4-port
asynchronous serial interface for the communication with external devices.
The board is to be used in a free PCI-5 V / 32 Bit slot. The PC is to comply with
the EU directive 89/336/EWG and the specifications for EMC protection.
Products complying with these specifications bear the normed
mark.
Serial data is exchanged with external communication devices through the
37-pin SUB-D male connector of the board
APCI-7501
in RS232 transmission
mode.
The board is to be connected to the peripheral through a shielded cable, which
shielding should be grounded on both ends.
The connection with our standard cable ST010 complies with the minimum
specifications as follows:
- metallized plastic hoods
- shielded cable
- cable shield folded back and firmly screwed to the connector housing.
The board supports serial communication through 4 asynchronous serial ports.
The intended purpose of the board depends on the following parameters.
