    • ERNI Components, Inc. (part number 033-273) The mating connector for the SCXI-1162 front connector is a special 48-pin reversed DIN C female connector. National Instruments uses a polarized and keyed connector to prevent inadvertent upside-down connection to the SCXI-1162. The manufacturer part number National Instruments uses for this mating connector is as follows: •...

  • Page 17: Configuration And Installation

    SCXI chassis, signal connections to the SCXI-1162, and cable wiring. Module Configuration You can configure the SCXI-1162 rear connector to send data directly from the inputs in parallel, or to form a serial communication link with the SCXIbus. You can also configure the rear connector to connect to a DIO-type or an MIO-type data acquisition board.

  • Page 19: Jumper Use

    All six user-configurable jumpers (W1-W6) on the SCXI-1162 are for digital communication through the rear connector between the data acquisition board and the SCXI-1162 module. If you are controlling the SCXI-1162 via the SCXIbus and are not using the rear connector, then the positions of these jumpers are irrelevant.

  • Page 20: Jumper W1

    W2 is set to PAR. Jumper W2 does not affect serial communication; therefore all 32 channels are always available through serial data transfers. When you connect the SCXI-1162 to a DIO-32F or to a DIO-96, all 32 lines may be driven. However, when you SCXI-1162 User Manual...

  • Page 21: Using Jumper W1

    SCXI-1162 with a DIO-type board, place the jumpers in the DIO position. This position is the factory setting. If you want to use the SCXI-1162 with an MIO-type board, place the jumpers in the MIO position. If you are controlling the SCXI-1162 via the SCXI backplane and are not using the rear connector, the position of these jumpers is irrelevant.

  • Page 22: Using Jumpers W5 And W6

    When you use a single chassis, set W5 in position A on the SCXI-1162 that is connected to the data acquisition board and set W6 to DIO or MIO. In this setting, the module drives MISO to SERDATOUT and connects the necessary pullup resistor to the SERDATOUT line.

    C14, C17, C21, C25, C29 The optically isolated inputs of the SCXI-1162 consist of a light-emitting diode and a 360 Ω series current limiting resistor. When current is pulled through an input, the diode emits light which is sensed by a photosensitive circuit. When this circuit senses the light, it outputs a logic low digital signal.

    When the rear connector is jumper configured for serial communication with the SCXIbus, the SCXI-1162 module converts the data acquisition board signals to open-collector signals on the backplane of the SCXI chassis. For the data acquisition board to talk to a slot, the board must first assert the SS* for that slot.

  • Page 49: Register Descriptions

    SCXI-1162 Registers The SCXI-1162 is a class II module. It has an address handler that chooses one of three registers. The Module ID Register is a 4-byte read-only register that contains the Module ID number of the SCXI-1162.

    After you select the Parking Register, SS* should go high, deselecting the module. At reset or at power up, the Address Handler content is cleared. SCXI-1162 User Manual © National Instruments Corporation...
  • Page 51 Register Descriptions Module ID Register The Module ID register contains the four-byte module ID code for the SCXI-1162. This code number is read on the MISO line whenever the Module ID register is accessed. The bytes appear least significant byte first. Within each byte, data is sent out MSB first. Additional data transfers result in all zeros being sent on the MISO line.

  • Page 52: Data Register

    Chapter 4 Data Register The Data Register contains 32 bits that control the state of each input of the SCXI-1162. Whenever the Address Handler selects the Data Register, it will latch in the data present on the inputs, then shift out one bit of the data onto the MISO line, bit 31 first, with each falling edge of SPICLK.

  • Page 53: Parking Register

    Selecting the Parking Register places the module in a state insensitive to noise and to ESD, which may corrupt the Data Register content and cause the relays to change state. Select the Parking Register by writing FFFF (hexadecimal) to the Address Handler. © National Instruments Corporation SCXI-1162 User Manual...
