    Jumper W5 must be set to position 1 The SCXI-1160 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 47: Digital Control Circuitry

    The digital interface circuitry is divided into a data acquisition section and an SCXIbus section. The SCXI-1160 connects to the SCXIbus via a 4x24 metral receptacle and to the data acquisition board via a 50-pin ribbon-cable header. The digital interface circuitry buffers the digital signals from the data acquisition board and the SCXIbus and sends signals back and forth between the data acquisition board and the SCXIbus.

  • Page 48: Relay Channels

    The Status Register is a 1-bit register that indicates whether or not the relays are switching. Relay Channels The SCXI-1160 consists of 16 independent one form C relays. Each relay has three connections at the front connector–the common (COM), the normally closed (NC), and the normally open (NO) positions, which are available at each relay.

  • Page 50: Register Descriptions

    SCXI-1160 Registers The SCXI-1160 is a class II module. It has four registers and an address handler. The Module ID Register is a 4-byte, read-only register that contains the Module ID number of the SCXI-1160.

  • Page 51: Module Id Register

    After you select the Parking Register, SS* should go high, deselecting the modules and latching all the data. At reset or at power up, the Address Handler content is cleared. SCXI-1160 User Manual © National Instruments Corporation...
  • Page 52 Register Descriptions Module ID Register The Module ID register contains the 4-byte module ID code for the SCXI-1160. 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 53: Data Register

    Chapter 4 Data Register The Data Register contains 32 bits that control the state of each relay of the SCXI-1160. Whenever the Address Handler selects the Data Register, the Data Register shifts in the data present on the MOSI line, bit 31 first, and then latches the data when it is deselected. At power up or reset, the Data Register content is unknown and its outputs are not driving the relay coils.
