  • Page 4: General Information

    When you open your TAMS GPIO Card shipment, examine its contents. Note: The name of the product you have purchased is the TAMS 81622 (GPIO Card for Linux). It includes the TAMS 622-66501 GPIO card and the t61622 card driver for Red Hat Linux. See the ReadMe for the version supported.

  • Page 5: Overview Of The Tams 81622 Gpio Interface

    A PCI expansion slot is required to accommodate the GPIO interface card. The TAMS GPIO card has a rotary DIP switch on the upper edge to set the unique identifier for the card. This is the only switch that needs to be set prior to installing the card.

  • Page 6: Installing The Interface

    Installing the Interface This section explains how to install the TAMS GPIO interface in the computer. To complete the installation: 1. Make sure the computer is shut down properly, the power is turned off, and the power cord is unplugged.

  • Page 7: Driver Installation

    Refer to your platform specific operating system documentation or contact your system administrator. To install the t61622 driver it is not necessary for the TAMS 622-66501 interface card(s) to be present in the system. Note: You must have root permission to install the software.
  • Page 8 Appendix B is a reference for the Linux systems administrator, who might wish to know where these files are placed. You will still need to configure the new TAMS GPIO card as a SICL interface card, as covered in the next section.

  • Page 9: Interface Configuration

    Libraries” chapter of the I/O Libraries Installation and Configuration Guide for Linux. For each TAMS 622-66501 card that you want to configure in your system, you need to add a line to the file. While most users do not need to hwconfig.cf...
  • Page 10 SIGUSR2 SIGIO or SIGURG. A value of 0 sets the default signal which is SIGURG. A signal is used by the t61622 driver to notify applications about kernel events. You can select an alternate signal to avoid conflicts within your application.
  • Page 11 The t61622 driver provides an alternate delay configuration method. The delay may be expressed in nanoseconds or in microseconds. If the delay is expressed in nanoseconds the decimal value representing that delay should be suffixed with “ns”. If the delay is expressed in microseconds the decimal value representing delay should be suffixed with “us”.

    Select Code used to identify the interface in their BASIC programs. More information for the use of the GPIO interface is found on the TAMS BASIC Documentation CD. Relevant sections are the “Linux Highlights” section of the BASIC Language Reference, and the GPIO chapter of the BASIC Interface Reference on the CD.

  • Page 13: Technical Information

    Technical Information This section provides a detailed, functional description of the TAMS 81622 GPIO interface. You will need to understand this information in order to set the appropriate configuration values. This information should also be helpful when you are preparing and installing the GPIO cable.

  • Page 17 Changes take effect when a session on a newly configured interface is started for the first time within a process. Care should be taken when a running application is using the TAMS GPIO interface while it is reconfigured.

  • Page 18: Appendix A: Wiring

    Appendix A: Wiring Data Lines There are 32 data lines on the TAMS GPIO: 16 designated as data input, and 16 designated as data output. Color codes are provided for the TAMS 622-001 GPIO cable and the HP 5061-4209 GPIO cable.

  • Page 22: Appendix C: Tams 61622 Sicl Extensions

    Appendix C: TAMS 81622 SICL Extensions All of the TAMS 81622 SICL extension functions are implemented by using the header file t61622sicl.h and the standard SICL functions igpioctrl and igpiostat. These two functions are described below: IGPIOCTRL Supported sessions: ......interface Affected by functions: .
  • Page 23 The TAMS 81622 PCTL delay function provides an extended PCTL delay control that was not available before. Besides the standard 0-7 values for delay used with HP cards, the delay of the TAMS 81622 may be set directly in nanoseconds.
  • Page 24 GPIO. If set to 1, polarity is reversed for these lines. • For DIN lines, 81622 extensions allow the user to set the polarity for each line independently. Setting the DIN polarity with standard GPIO SICL igpioctrl ) is still supported and will cause the I_GPIO_POLARITY, setting setting or clearing of all the DIN lines’...

  • Page 26 I_GPIO_T61622_PUL, 0) TAMS 81622 Board ID The 81622 is equipped with a rotary DIP switch. Its purpose is the identification of each GPIO board on a system with multiple GPIO cards. The user must set the switch position to a unique value for each card on the system and then can read its value by using the request I_GPIO_T61622_CID to check which physical card is associated with a specific opened session.
