1General Information

The Quatech, Inc. DSCLP-200/300(two-port) and SSCLP-200/300

(one-port) provides upto provides two RS-422 or RS-485 asynchronous serial

communication interfaces for IBM-compatible personal computer systems using the

PCI expansion bus. The DSCLP-200/300 uses Quatech's new Enhanced Serial

Adapter design. Legacy serial port data rates are limited to a maximum of 115,200 bits

per second. Quatech Enhanced Serial Adapters can achieve data rates as high as

460,800 bits per second. This discussion relates to DSCLP-200/300.A

SSCLP-200/300 is just one port in the discussion.

As a PCI device, the DSCLP-200/300 requires no hardware configuration.

The card is automatically configured by the computer's BIOS or operating system. The

two serial ports share a single interrupt line and are addressed in a contiguous block of

16 bytes. Aspecial interrupt status register is provided to help software to manage the

shared interrupt.

The DSCLP-200/300's serial ports are implemented using 16550 Universal

Asynchronous Receiver/Transmitters (UARTs). These UARTs contain hardware

buffers (FIFOs) which reduce processing overhead and allow higher data rates to be

achieved. The 16550 contains a 16-byte FIFO and can transmit and receive data at a

rate of up to 230,400 bits per second.

The DSCLP-200/300 is supported under several popular operating systems

and environments. Contact the sales department for details on current software

offerings. Most device drivers are available for download from the Quatech world wide

web site at http://www.quatech.com.

DSCLP-200/300 User's Manual 1

2Hardware Configuration

The DSCLP-200/300 is automatically configured at boot time by the

computer's BIOS or operating system. There are no required switches or jumpers to

set for installation.

This chapter lists a number of jumper settings that control various hardware

features. Jumpers J1-J4,located in a column near the D-9 connectors, control the

RS-422 or RS-485 signal line termination. Jumpers J5-J8, located in a column just to

the right of J1-J4, control how signals are routed from the UARTs to the connector, as

well as full- or half- duplex operation. Jumpers J10-J13, grouped together at the end of

the board opposite the D-9connectors, control special options.

Any changes from the factory default should be made before installing the

DSCLP-200/300 in the computer.

2.1RS-422 or RS-485 Signal Line Termination

Jumpers J6-J9allow the selection of 100-ohm RS-422 termination, 120-ohm

RS-485 termination, or no termination at all. The factory default, shown in Figure 1, is

RS-422 termination. For full details, see page 24.

2.2Signal Connections

The DSCLP-200/300 provides each of two serial ports with four differential

signal pairs: TxD, RxD, AUXOUT, and AUXIN. TxD and RxD are always present at

the connector. The AUXOUT and AUXIN signals can be used to support RTS/CTS

handshaking, external clocking, or external signal loopback. The factory default

configuration, as shown in Figure 2, is a loopback of AUXOUT to AUXIN at the

connector, with RTS and CTS looped back on the board. There is an extensive

discussion of this topic starting on page 19.

2.3Full-duplex/Half-duplex Operation

The DTR or RTS modem control output of the UART can be used to enable

and disable the transmit drivers. The inverse of these signals can also be used to enable

and disable the receivers. These options are selectable per channel. The factory

default, as shown in Figure 2, is for both the drivers and receivers of both channels to

be continuously enabled. Two spare jumpers are installed in neutral positions. For

details, refer to page 22.

The DSCLP-200/300 is shipped from the factory with each channel configured

with No jumpers on J10-23. The following conditions occur: CTS=AUXIN,

AUXOUT=RTS, RCLK=TCLK, TXEN=1 AND RXEN=1.

Jumpers J10-J23 define the options for this card:

2.4Clock Rate and Optional Registers

Figure 3 shows the jumper configuration as shipped from the factory, with two

spare jumpers applied in neutral positions. Remove one or both and apply as shown in

following subsections to set optional features.

2.4.1Enable Scratchpad Register (SPAD, J2)

In the default configuration, an Interrupt Status Register and an Options Register

(see page 10) replace the scratchpad (base address + 7) of each UART. If the SPAD

jumper is applied as in Figure 4, the UART scratchpad registers are enabled, and the

Interrupt Status Register and the Options Register are not available.
