DS-100 Asynchronous Serial Adapter RS-232 for AT (DS-1000 for MCA)

FEATURES:

*Two independent RS-232 serial interfaces

*AT bus (16 bit) compatible

*Selectable and shareable interrupt features

*Programmable baud rates to 56 Kbaud (Optional 16550s available)

*DTE/DCE selection

DESCRIPTION:

The DS-100 is a two channel asynchronous serial RS-232 communication adapter with versatile interrupt selection for the IBM AT. The adapter features  the  extended 16-bit AT bus,  which  provides access to the computer's additional interrupts. The DS-100  has a versatile interrupt feature which allows  the user  to select the desired interrupt, or to share  an  interrupt with  another device. Users may select from interrupts  IRQ2-7, 10-12 or 14-15.

The extended base address capability of the DS-100 supports any COM port. Two 16450  UART's  provide  two  independent ports, allowing the user to communicate to two separate devices. The DS-100  supports baud rates to 56K (maximum of 256K with optional 16550). In case a  limited  number of interrupt levels  are  available  for system  expansion, the DS-100 is capable of sharing an interrupt with another device with the same feature.

ADDRESSING:

Both serial communication ports have user-selectable addresses via two DIP switches. These switches allow each serial port to reside anywhere in the I/O space on eight byte boundaries. Bits A0, A1, and A2 are used to access the eight internal registers of the 16450. Each channel also offers enable/disable capabilities.

Decoding of all 16 address lines provides compatiblity with systems using COM3 at 3220H and COM4 at 3228 while also greatly reducing the possibility of addressing conflicts in I/O intensive systems.

DS-200/DS-300 Asychronous Serial Adapter RS-422/RS-485 for AT (DS-2000/DS-3000 for MCA)

FEATURES:

*Two independent interfaces

*AT bus (16 bit) compatible

*RTS-CTS Control Lines Available

*Balanced RS-422 or RS-485 differential driver and receivers.

*Maximum data transfer to 56Kbaud  (Optional 16550s available)

DESCRIPTION:

The DS-200 is a two port asynchronous serial RS-422 (DS-300 for RS-485) communication adapter with versatile interrupt selection for the IBM AT. The adapter features  the  extended 16-bit AT bus,  which  provides access to the computer's additional interrupts.

The DS-200  has a versatile interrupt feature which  allows the user to select the desired interrupt, or to share  an interrupt with  another device. Users may select from interrupts IRQ2-7, 10-12 or 14-15.

The extended base address capability of the DS-200 supports any COM port. Two 16450  UART's  provide  two  independent ports, allowing the user to communicate two separate devices. The DS-200  supports a maximum baud rate of 56K bits per second, 256K with 16550. In case a limited number of interrupt levels are available for system expansion, the DS-200 is capable of sharing an interrupt with another device with the same feature.

DSDP-100 Serial Communication 2 RS-232 and 2 Parallel Channels (SP-1000/SP-1050 for MCA provide similar function)

FEATURES:

2 Independent bi-directional parallel printer ports

Two independent RS-232 serial ports

All ports are address selectable

All ports have selectable/shareable interrupts (IRQ2-IRQ7)

Optional 16550 UARTs available

DESCRIPTION:

The DSDP-100 is a multiple channel communication board which supports two parallel ports and two RS-232 serial ports. Each serial port uses a 16450 UART supporting baud rates to 56K. Optionally available are 16550 UARTs which support baud rates to 256K and provide an additional FIFO mode to reduce CPU overhead. Each Centronics compatible parallel interface consists of an eight bit bi-directional data port, a five bit status port, and a five bit command port.

Each printer port of the DSDP-100 supports bi-directional data transfer. This feature allows data to be input through the printer interface. Both the serial and parallel interfaces are address selectable allowing the ports to be installed in the computer without conflicting with other devices. Each port may also be individually enabled or disabled. Versatile interrupt circuitry allows each port access to IRQ2-IRQ7. The DSDP-100 also has interrupt sharing capabilities, allowing it to share interrupts with other Quatech adapters supporting this feature.

The DSDP-100 occupies only one expansion slot in the PC. All ports may be accessed through a high density D-62 connector. An adapter cable is included to convert the D-62 into 2 D-25 female (parallel port) and 2 D-25 male (serial port) connectors.

ADDRESS/INTERRUPT SELECTIONS:

All four ports of the DSDP-100 are address selectable using a block of 8 dip switches. This allows each serial port to reside in any 8-byte I/O address range from 0000H to 03F8H. Similarly the parallel ports may reside in any 4-byte I/O address range from 0000H to 03FCH.

Each port of the DSDP-100 may select an interrupt in the range IRQ2-IRQ7 using a six position jumper block. An interrupt sharing circuit implemented on the board allows multiple ports to share the same interrupt level or to share the interrupt with another Quatech adapter supporting this feature.

Each port of the DSDP-100 can be enabled or disabled by setting the appropriate jumper as defined in the manual.
