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.x environments. For optimal operation, however, the Clie nt Driver is the prefer[...]

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. IMPORTANT: Some versions of Card and So cket Services dated before 1993 do not support ge[...]

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. 2.1.2 Command Line Options The DSP-200/300 Client Driver accepts up to ei g ht command line arguments from the user to determine the configuration of theDSP-20[...]

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. If address 300H or I RQ 5 is unavailable, the DSP-200/[...]

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. If[...]

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. Card and Socket Services so[...]

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. This arg ument must be enclosed in parenthesis a nd within the argument, any or all of the following para meters may be specified using a comma (no spaces) to separate each [...]

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. The auxiliary channel may then be used for handshaking between the DSP-200/300’s RS-422/485 port and a periphe ral de[...]

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 2.2.1.[...]

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. Socket Numbers[...]

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. In addition, the aux iliary output and input si gnals will be looped back to each other. Th[...]

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. I n half duplex mode, the RS-422/485 transmitte r may be enabled and disabled via the RTS (request to sen[...]

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. CAUTION: When operating in half duplex m ode, the transmitter output drivers mus t b e disabled[...]
