1 Introduction The Quatech QSP-200/300 provides four independent RS-422/485 asynchronous serial communications interfaces for systems equipped with PCMCIA Type II and/or Type III expansion sockets. The QSP-200/300 is a PCMCIA Type II (5 mm) card and is PCMCIA PC Card Standard Specification 2.1 compliant.
2 Windows 95/98/ME/2000/NT Installation Windows 95/98 maintains a registry of all known hardware installed within the computer. Inside this hardware registry Windows 95/98 keeps track of all the computer's resources, such as base I/O addresses, IRQ levels, and DMA channels. In the case of a PC Card (PCMCIA) type board, Windows 95/98 configures the new hardware using free resources it finds within the hardware registry, and updates the registry automatically.

3 Windows CE The Quatech PCMCIA Windows CD installation copies a multiple device-specific .cab files and the ini file to your desktop computer and launches the Application Manger (which resides on the user's desktop computer as a result of installing Active Sync) with the Application Manager .ini file as a parameter. This in turn will install the driver onto the Windows CE connected device or if not connected will install it on the next device connection to the desktop. 1.
3. The setup program will copy the files to predetermined location, which can be changed by the user. Click next to proceed.. Installation is now complete. In the event that installation process took place with out having the Windows CE device connected to the computer and the install program will prompt the user that on the next on the next connection the device will complete the installation. Choose ‘Yes’ on the following window and you installation is now complete.
4 DOS / Windows 3.x Installation Two configuration software programs are provided with the QSP-200/300: a Client Driver, QSP200CL.SYS, and a card Enabler, QSP200EN.EXE. Both of these programs are executed from DOS (before entering Windows) and allow operation of the QSP-200/300 in both the DOS and Windows 3.x environments. For optimal operation, however, the Client Driver is the preferred method of installation and configuration. The table below highlights the differences between these programs.
4.1 QSP-200/300 Client Driver for DOS In order to use the QSP-200/300 Client Driver, the system must be configured with Card and Socket Services software. Card and Socket Services software is not provided with the QSP-200/300. IMPORTANT: Some versions of Card and Socket Services dated before 1993 do not support general purpose I/O cards. If after careful installation of the Client Driver the QSP-200/300 does not configure or operate properly, an updated version of Card and Socket Services may be required.
correct the entry in the CONFIG.SYS file and reboot the system again. If the Client Driver reports "Card and Socket Services not found", a version of Card and Socket Services must be installed on the system or the QSP-200/300 Enabler program must be used to configure the adapter. If the Client Driver reports the desired adapter configuration, the installation process is complete and the QSP-200/300 may be removed and / or inserted from the system as desired.
o1 o2 DTR Controlled RTS Controlled Figure 3. DOS Client Output Driver Options. H instructs the client driver to enable the RTS-CTS modem control handshake. When modem control handshaking in enabled, the 16C550 UART’s RTS and CTS signals are connected to the RS-422/485 auxiliary channel (AuxOut and AuxIn). The auxiliary channel may then be used for handshaking between a DSP-200/300 RS-422/485 port and a peripheral device.
4.1.3 QSP-200/300 Client Driver Examples Example 1 DEVICE = C:\QSP-200\QSP200CL.SYS In example 1, no command line arguments are specified. The Client Driver will configure a QSP-200/300 inserted into any socket with a base address and IRQ assigned by Card and Socket Services. The output drivers will be configured for full duplex operation (always enabled), the RTS-CTS handshaking will be disabled (loopback mode), and the interrupt status register will be enabled. Example 2 DEVICE = C:\QSP-200\QSP200CL.
Example 4 DEVICE = C:\QSP-200\QSP200CL.SYS (i5,h,u,b300,o2) In example 4, a single command line argument is provided. Because the parameter order is not significant, the Client Driver will attempt to configure a QSP-200/300 inserted into any socket with a base address of 300H and IRQ 5. If address 300H or IRQ 5 is unavailable, the card will not be configured.
Example 6 DEVICE = C:\QSP-200\QSP200CL.SYS (b300,i5) ( ) (i10) In example 6, the three command line arguments of example 5 have been rearranged. The Client Driver will first attempt to configure a QSP-200/300 inserted into any socket with a base address of 300H and IRQ 5. If address 300H or IRQ 5 is unavailable, the Client Driver will proceed to the second command line argument and attempt to configure the card with a base address and IRQ assigned by Card and Socket Services.
4.1.4 Common Problems Generic Client Drivers: Many Card and Socket Services packages include a generic client driver (or "Super Client") which configures standard I/O devices. If one of these generic client drivers is installed, it may configure the QSP-200/300 causing the QSP-200/300 client driver to fail installation. In these cases, the user should do one of the following: 1. modify the operation of the generic client driver to disable the configuration of modem/serial port cards.
IMPORTANT: In order to use the QSP-200/300 Enabler for DOS, the system MUST NOT be configured with Card and Socket Services software. If a Card and Socket Services software is installed, the QSP-200/300 Enabler may interfere with its operation and with the device(s) it controls. The QSP-200/300 Enabler does not support automatic configuration of adapters upon insertion, more commonly referred to as "Hot Swapping".
4.2.1 Command Line Options To configure a QSP-200/300 in the system, the Enabler requires one command line argument from the user to determine the configuration of the card. This argument must be enclosed in parenthesis and within the argument, any or all of the following parameters may be specified using a comma (no spaces) to separate each parameter: Ssocket specifies which PCMCIA socket the QSP-200/300 must be inserted into for this configuration argument to be used. socket must be in the range 0 - 15.
other. If this option is omitted, the default setting is RTS-CTS modem control handshake disabled. See the Hardware Information section for more information. U instructs the Enabler to disable the QSP-200/300's interrupt status register and enable the Scratchpad registers of the individual UARTs. This option is only required in very rare cases where an application program requires access to the UART's Scratchpad register.
4.2.2 QSP-200/300 Enabler Examples Example 1 QSP200EN.EXE In example 1, no command line argument is specified. The Enabler will report an error and display the proper usage of the command. Example 2 QSP200EN.EXE (s0,b300,i5) In example 2, the Enabler will configure the QSP-200/300 in socket 0 with a base address of 300H and IRQ 5 using a configuration memory window at segment D000.
Example 5 QSP200EN.EXE (s0,b300,i5,r) In example 5, the Enabler will release the configuration used by the QSP-200/300 in socket 0 using a configuration memory window at segment D000. The base address and IRQ parameters are ignored and may be omitted. Example 6 QSP200EN.EXE (s1,r,wcc) In example 5, the Enabler will release the configuration used by the QSP-200/300 in socket 1 using a configuration memory window at segment CC00.
4.2.3 Common Problems Memory Range Exclusion: The Enabler requires a region of high DOS memory when configuring a QSP-200/300. This region is 1000H bytes (4KB) long and by default begins at address D0000H (the default address may be changed using the "W" option). If a memory manager such as EMM386, QEMM, or 386Max is installed on the system, this region of DOS memory must be excluded from the memory manager's control.
5 OS/2 Installation In order to use the QSP-200/300 Client Driver for OS/2, the system must be configured as follows: 1. The system must be running OS/2 2.1 or later. 2. OS/2 PCMCIA Card and Socket Services support must be installed. If PCMCIA support was not selected when OS/2 was installed, it can be added using the Selective Install facility in the System Setup folder. On OS/2 2.1 and 2.11, Socket Services must be added separately.
5.1 Command Line Options The QSP-200/300 Client Driver for OS/2 supports two methods of configuration: using "system assigned" resources and using "user assigned" resources. Both options provide full PCMCIA compliance and functionality (including "Hot-swapping") but each has some advantages and disadvantages as discussed in the following sections. 5.1.
5.1.2 Configuring With "User Assigned" Resources As mentioned in the previous section, allowing the OS/2 Plug-and-Play system to assign the hardware resources to the QSP-200/300 is ideal for OS/2 programs but can be a problem if DOS and/or Windows applications will be accessing the serial ports. This is because most DOS applications write directly to the communications hardware and the Windows' Control Panel also wants to know the hardware configuration of the serial ports.
Example 2 DEVICE=C:\QSP-200\QSP200.SYS (7,120,15) (3,300,4) In example 2, the Client Driver will attempt to configure the QSP-200/300 as COM3 through COM6 using I/O address 300-31F hex and IRQ 4. If COM3, 4, 5, or 6 already exists, or if the I/O address or IRQ resources are already in use, the Client Driver will attempt to configure the QSP-200/300 as COM7 through COM10 using I/O address 120-13F hex and IRQ 15.
5.2 Monitoring The Status Of PCMCIA Cards OS/2 Warp provides a utility called "Plug and Play for PCMCIA" that can be used to monitor the status of each PCMCIA socket. In OS/2 2.1, this utility is called "Configuration Manager". When a QSP-200/300 is inserted, the Card Type for the appropriate socket will display "Multi-Function". If the card is successfully configured, the Card Status will display "Ready". If the card cannot be configured, the Card Status will be "Not Ready".
5.3 Common Problems Invalid I/O Address When Using OS/2 2.1: PCMCIA Card Services for OS/2 2.1 sometimes fails to supply a valid I/O address when using "system assigned" resources. Use the "Configuration Manager" program to examine the I/O address range assigned to the QSP-200/300. If this range does not begin on an even 32 byte (20H) boundary, the QSP-200/300 will have to be installed using "user assigned" resources to force a valid configuration.
6 Hardware Information 6.1 Port Addressing The QSP-200/300's four asynchronous serial ports are implemented using 4 standard 16C550 UARTs. Each of these UARTs requires 8 bytes of I/O space and when enabled which requires the QSP-200/300 to be located on an even 32-byte (20H) boundary (e.g. 300H, 320H, 340H, etc.). QSP-200/300 channel Address assignment Channel A Base Address + 0 Channel B Base Address + 8 Channel C Base Address + 16 Channel D Base Address + 24 6.
6.3 Auxiliary Channel Configuration An auxiliary channel is provided which allows for handshaking between a QSP-200/300 RS-422/485 port and a peripheral device. This auxiliary channel may be configured in one of two ways: RTS-CTS handshake enabled. handshaking is disabled. All ports must be configured in the same manner. 6.3.
6.3.2 Auxiliary Channel: Handshaking Disabled The QSP-200/300 ports may be configured so that the RTS-CTS handshake is disabled. This is the default configuration. In this configuration, RTS and CTS from the 16C550 UART will be looped back to each other. In addition, the auxiliary output and input signals will be looped back to each other.
6.4 Termination Resistors No termination resistors are provided on the QSP-200/300 ports. Both output and input signals are connected only to the external connector. Any termination which is required must be added externally. RS-422/485 Receiver RXD+ + Rt - RXD- RS-422/485 Receiver AUXIN+ + Rt - AUXIN- Recommended Termination Resistor Values RS-422 100 ohm 1/2W resistor RS-485 60 ohms total resistance (120 ohms at each end) Figure 7.
