  • Page 7: Dos/Windows 3

    2. DOS/Windows 3.x Two configuration software programs are provided with the SSP-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 SSP-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.

  • Page 8: Ssp-200/300 Client Driver For Dos

    2.1 SSP-200/300 Client Driver for DOS In order to use the SSP-200/300 Client Driver, the system must be configured with Card and Socket Services software. SSP-200/300 but is available from Quatech. IMPORTANT: Some versions of Card and Socket Services dated before 1993 do not support general purpose I/O cards.

  • Page 9: Command Line Options

    2.1.2 Command Line Options The SSP-200/300 Client Driver accepts up to eight command line arguments from the user to determine the configuration of theSSP-200/300. If any arguments are provided, the Client Driver will attempt to configure any SSP-200/300s with the options specified in the order they are entered on the command line.
  • Page 10 In example 2, a single command line argument is provided. The Client Driver will attempt to configure a SSP-200/300 inserted into any socket with a base address of 290H and IRQ 11. If address 290H or IRQ 11 is unavailable, the SSP-200/300 will not be configured. If the Client Driver can successfully configure the SSP-200/300unit, the RS-422/485 output drivers will always be enabled, and RTS-CTS modem control handshaking will be disabled.
  • Page 11 In example 5, three command line arguments are provided. The Client Driver will first attempt to configure a SSP-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 assigned by Card and Socket Services and IRQ 10.

  • Page 12: Common Problems

    SSP-200/300 is to be installed. In this example, the Client Driver will attempt to configure a SSP-200/300 inserted into socket 0 with a base address of 300H and IRQ 5. If the SSP-200/300 is inserted into socket 1, the Client Driver will attempt to configure it with base address 340H and IRQ 10.

  • Page 13: Ssp-200/300 Enabler For Dos

    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 SSP-200/300 does not configure or operate properly, an updated version of Card and Socket Services may be required. Card and Socket Services software is available from Quatech.

  • Page 16 2.2.1.2 Example 2 SSP231EN.EXE (s0,b300,i5) In example 2, the Enabler will configure the SSP-200/300 in socket 0 with a base address of 300H and IRQ 5 using a configuration memory window at segment D000. The SSP-200/300 unit's RS-422/485 output drivers will always be enabled, and RTS-CTS modem control handshaking will be disabled.

  • Page 17: Common Problems

    2.2.1.6 Example 6 SSP231EN.EXE (s0,b300,i5,r) In example 6, the Enabler will release the configuration used by the SSP-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.

  • Page 43: Hardware Information

    6. Hardware Information 6.1 Auxiliary Channel Configuration An auxiliary channel is provided which allows for handshaking between the SSP-200/300 port and a peripheral device. This auxiliary channel may be configured in one of two ways: v RTS-CTS handshake enabled. v handshaking is disabled.

  • Page 44: Auxiliary Channel: Handshaking Disabled

    6.1.2 Auxiliary Channel: Handshaking Disabled. The SSP-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 16C750 UART will be looped back to each other. In addition, the auxiliary output and input signals will be looped back to each other.

  • Page 45: Half Duplex Operation

    6.2 Half Duplex Operation The SSP-200/300’s ports may be configured 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. In half duplex mode, the RS-422/485 transmitter may be enabled and disabled via the RTS (request to send) or DTR (data terminal ready) signals.
  • Page 46 Selection of half duplex mode operation is dependent upon the configuration software and/or the operating system used. Each of these, however, ultimately control the half duplex mode by accessing the PCMCIA Configuration Register on the SSP-200/300. CAUTION: When operating in half duplex mode, the transmitter output drivers must be disabled before receiving any information.
