2. DOS/Windows 3.x Two configuration software prog rams are provided with the DSP- 200/300: a Client Driver, and a card Enabler. Both of these programs are executed from DOS (before entering Windows) and allow operation of the DSP-200/300 in both th e DOS and Windows 3.
2.1 DSP-200/300 Client Driver for DOS I n order to use the DSP-200/300 Client Driver, th e sy stem must be configured with Card and Socket Services soft ware. Card and Socket Services software is not provided with the DSP-200/300 but is available from Quatech.
removed and/ or inserted from the sy stem as de sired. On e ach insertion into the PCMCI A socket, the DSP-200/300 will be au tomatically reconfig ured according to the command line options.
H instructs the client driver to ena ble the RTS-CTS modem cont rol handshake on the RS-422/485 port. When modem contro l handshaking in enabled, the 16C750 UART’s RTS and CTS signals are connected to the RS-422/485 auxiliary channel. The auxiliary channel may then be used for handshaking between the DSP-200/300’s port and a peripheral device.
2.1.2.4 Example 4 DEVICE = C: DSP-200DSP230CL.SYS(i5,h,b300) I n exampl e 4, a single command li ne argument is provided. Because the parameter order is not significant, the Client Driver will attempt to configure a D SP-200/300 inserted into any socket with a base address of 300H and I RQ 5.
2.1.2.7 Example 7 DEVICE = C: DSP-200DSP230CL.SYS (s0,b300,i5) (s1,b340,i10) The ty pe of configuration shown in example 7 ma y be desirable in sy stems where more than one DSP-200/300 is to be installed. I n this ex ample, the Client Driver will attempt to config ure a DSP-200/300 inserted into socket 0 with a base address of 300H and I RQ 5.
Older Versions of Card and Socket Services: Some versions of Card and Socket Services dated before 1993 do not support g eneral purpose I /O cards. If after careful installation of the Client Driver the DSP- 200/300 does not configure or operate properly , an updated vers ion of Card and Socket Servi ces may be required.
2.2.1 Command Line Options To configure a DSP-200/300 in the system, th e Enabler requires one command line arg ument from the user to determine the config uration of the card.
H instructs the enabler to enabl e the RTS-CTS modem contro l handshake on the RS-422/485 port. When modem contro l handshaking in enabled, the 16C750 UART’s RTS and CTS signals are connected to the RS-422/485 auxiliary channel.
2.2.1.4 Example 4 DSP230EN.EXE (s0,b300,i3,wd8) I n example 4, the Enabler will configure the D SP-200/300 in socket 0 w ith a base address of 300H and I RQ 3 using a configuration memory window at segment D800. The DSP-200/300' s RS-422/485 output drivers will alway s be enab led, and RTS-CTS mode m control handshaking will be disabled 2.
Furthermore, some sy stems use the high memo ry area for BI OS shadowing to improve overall sy st em performance. In order for the Enabler to operate, any BI OS sha dowing must be disabled in the address range specified for the config uration window. BIOS shadowing can usually be disabled through the system's CMOS setup utility.

5 Windows NT 5.1 Installing DSP-200/300 To allow easy configuration of the DSP-200/300 the Quatech Device Manager for Windows NT has been written for the hardware. This configuration util ity supports the DSP-200/300 only in block addressing mode. To begin the installation, open Windows Explorer and search for the ‘Setup.
1. Locate and double click the Quatech Device Manager icon on the desktop Device Manager Icon on Desktop 2. Click the ‘Add’ button at the bottom of the Quatech Device Manager Window 5-3 DSP-200/300 (Rev.
3. Follow the steps for the ‘Add Quatech Hardware Wizard’. Windows NT 5-4.
4. Complete the final steps of the installation, shut down Windows NT and then insert the PCMCIA Card and re-boot the computer. Additional help is available online The DSP-200/300 PC Card should now be configured. In the future, Windows NT will automatically recognize and configure the DSP-200/300.
6. Hardware Information 6.1 Auxiliary Channel Configuration An auxiliary channel is provi ded which allows for handshaki ng between the DSP-200/300 port and a peripheral device. This auxiliary channel may be configured in one of two ways: v RTS-CTS handshake enabled.
6.1.2 Auxiliary Channel: Handshaking Disabled. The DSP-200/300 ports may be config ured so that the RTS-CTS hands hake is disabled. This is the default configuration. I n this configuration, RTS and CTS from the 16C750 UART will be looped back to each other.
6.2 Half Duplex Operation The DSP-200/300’s ports may be c onfigured for either full duplex or half duplex operation. By default, the RS-422/485 ports are configured for full duplex operation with the RS-422/485 output drivers always enabled.
Selection of half duplex mode operation is dependent upon the conf ig uration software and/or the operating sy stem used. Each of these, howev er, ultimately control th e half duplex mode by accessing the PCMCIA Configuration Register on the DSP-200/300.
6.3 Termination Resistors No termination resistors are provided on the DSP-200/300 ports. B oth output and input sig nals are connected only to the ext ernal connector.
