    INSTALLATION 2.1 OVERVIEW This chapter describes how to install the SSIO-24. It details how to select a source of power and the ports to be used. Figure 2-1 shows the loca- tion of the Port Direction Switch, in addition to the Terminal Block used to select the power source.
  • Page 12 I/O board. • Control signals come from a KPCMCIA-PIO24 module. The KPCMCIA-PIO24 does not supply +5V to the SSIO-24. There- fore, you must supply all +5V signals externally, including the +5V that a PC would otherwise supply to the PC terminal on TB7.

    8-bit ports (Ports A and B) and one 8-bit port usable as two 4-bit ports (Port C HI/LOW). Each of these 8255 PPI ports corresponds to a port on the SSIO-24. Port Direction Switch S1 (see Figure 2-1) selects the direction of each of these ports.

    LOW. The SSIO-24 monitors this transition from a logic HIGH level to a logic LOW level at the Þrst bit of each of the four (4) ports. As soon as the SSIO-24 detects this transition at a port, it enables the OUTPUT modules connected to that port.
  • Page 15 This mode works by sensing the Port C7 line of a PIO-XX board. When this bit is high, the SSIO-24 is RESET. When this bit is low, the RESET to the SSIO-24 is removed (NOTE: you must wait a minimum of 200 ms after removal of the SSIO-24 RESET before enabling the OUTPUT ports).

    OUTPUT modules of the SSIO-24. 2.5 INSTALLATION The SSIO-24 mounts on a ßat panel or other ßat surface, or it installs in an external rack-type enclosure (such as the Keithley RMF-06 or RTT-02). Rack-type enclosures require an adapter such as the Keithley RMT-02.
  • Page 17 SSIO-24. Be very careful to observe the direction of the ports on the SSIO-24 (refer to the Port Direction Switch). For example, if Port A on the SSIO-24 is set for INPUT, then Port A on the Parallel I/O card must be set for INPUT.

    All digital I/O is through a standard 37-pin D-type male connector or through a 50-pin PIO-96 type connector. The connector pin assignments are shown in Figures 2-6 and 2-7. Figure 2-6. 37-pin connector assignments 2 - 8 SSIO-24 USER GUIDE...
