ETC - 9081
DESCRIPTION:
The ETC-9081 PC-card is equipped with 2 serial RS-232 ports and 2 parallel Centronics
ports. Any parallel or serial standard address, as well as any free 16-Bit interrupt can be
assigned to each port.
In addition to the 4 standard Adresses COM1-COM4, it is also possible to select one of
the 4 alternative addresses: COM5-COM8. In this way it is possible to operate more than
the 4 standard COM-ports available. In order to use the alternative COM addresses
(COM5-COM8), the addresses must be set in the software application.
Optionally, the card can be equipped with 1 or 2 serial 550 FIFO ports (16C550). This is
especially recommended for high speed serial transfers. It increases the data transfer
rate, prevents loss of date and reduces the CPU's workload.
The extended 16-Bit address decoding makes it simple to install COM4 even in systems
with graphic cards which work in 8514 standard mode (e.g. S3 chip).
The compact size (short 16-Bit card) and the 35cm-long connecting cable make
installation simple even in a large tower casing.
The ETC-9081 is compatible with all ISA and EISA systems with 286, 386, 486 and
Pentium processors.The Bus clock rate can be as high as 16 Mhz which increases
system performance (8MHz is standard).
CONFIGURATION:
The ETC-9081 is equipped with 2 jumper blocks for every port; one to select the
address, and one for the interrupt.
Use the jumpers to select the required function. If the jumper is unplugged, the port or
interrupt is deactivated.
If you wish to use the ETC-9081 in addition to interfaces already present, please
determine the port addresses already in use by observing the BIOS report generated
when you boot your system or with the help of a suitable diagnostic program, e.g. MSD.
Now select the free port addresses on the ETC-9081.
