  • Page 7: General Description

    1.0 GENERAL DESCRIPTION The M220 provides two separate 8 to 1, two-wire multiplexers or you can move a jumper to connect the common channels of each multiplexer together and create a single 16 to 1, two-wire multiplexer on a single wide M-Module adhering to the ANSI/VITA 12-1996 specification for M- Modules.

  • Page 8: Specifications

    1.2.2 Specifications The M220 incorporates the standard 40-pin, 20x2 row connector interfaces to the carrier board for power and data/control, but does not have the 24-pin optional connector for carrying user- connections back onto the carrier board. The user input/output is provided through a standard 44-pin D-subminiature female receptacle. A mating connector kit can be ordered separately as AM111 (C&H Part Number 11029700-0001).

  • Page 9: Mechanical

    1.2.3 Mechanical The mechanical dimensions of the module are in conformance with ANSI/VITA 12-1996 for single-wide M-Module modules. The nominal dimensions are 5.687” (144.5 mm) long  2.082” (52.9 mm) wide. 1.2.4 Bus Compliance The module complies with the ANSI/VITA 12-1996 Specification for single-wide M-Modules and the MA-Module trigger signal extension.

  • Page 11: Installation

    2.0 INSTALLATION 2.1 UNPACKING AND INSPECTION Verify that there has been no damage to the shipping container. If damage exists then the container should be retained, as it will provide evidence of carrier caused problems. Such problems should be reported to the shipping courier immediately, as well as to C&H. If there is no damage to the shipping container, carefully remove the module from its box and anti static bag and inspect for any signs of physical damage.

  • Page 12: Preparation For Reshipment

    2.4 PREPARATION FOR RESHIPMENT If the module is to be shipped separately it should be enclosed in a suitable water and vapor proof anti-static bag. Heat seal or tape the bag to insure a moisture-proof closure. When sealing the bag, keep trapped air volume to a minimum. The shipping container should be a rigid box of sufficient size and strength to protect the equipment from damage.

    3.1.3 ID EEPROM The EEPROM holds sixty-four 16-bit words of M-Module ID data and VXI M-Module data. Refer Section 3.2.3 for more details. 3.1.4 Row and Column Drivers The module uses a matrix drive scheme (rows and columns) in which a maximum of four of the relays (one row) can be operated at any one time.

    3.2 IDENTIFICATION AND CONFIGURATION REGISTERS 3.2.1 Setting Multiplexer Size Figure 4 shows the two jumper positions for the M220. When in position A (jumper not connecting one row of pins), the module is configured as a dual 8-to-1 multiplexer. When in position B (jumper connecting all pins), the module is configured as a single 16-to-1 multiplexer.

  • Page 17: I/O Registers

    3.2.2 I/O Registers There are a variety of registers used to configure and control the M219 module. These registers are located in the IOSpace. The address map of the registers is shown in Table II. Details of the registers are provided in Figure 5. Table II.

  • Page 20: Module Identification

    3.2.3 Module Identification The M220 supports the identification function called IDENT. This IDENT function provides information about the module and is stored in a sixteen-word deep (32 byte) serial PROM. Access is accomplished with read/write operations on the last address in IOSpace (hex FE) and the data is read one bit at a time.

  • Page 21: Operation

    4.0 OPERATION The M220 is a register-based instrument that is controlled through a series of I/O registers described in Section 3.2.2. The exact method of accessing and addressing the I/O registers is dependent on the M-Module carrier used to interface the module to your data acquisition or test system.

  • Page 22: Matrix Drive To Channel Mappings

    3. The Row n Set/Reset readback registers return the programmed relay state only if you use the module correctly. Since the driver power can be disabled (the power-on state), the Row n Set and Row n Reset registers can be written to and read from without moving any relay contacts.
  • Page 23 If the M-Module is enabled to interrupt, it asserts the INT line on the M-Module interface to the Carrier when the last commanded relay operation in the FIFO has completed. For example, if relays in only one row were instructed to move, the module asserts an interrupt after that one row has been driven.

  • Page 25: Appendix A: Connectors

    APPENDIX A: CONNECTORS MAXIMUM VOLTAGE/CURRENT. The maximum voltage that may be applied to any connector on the M220 is 200 VDC, 125 VAC rms, or 175 VAC peak--these limits apply only if the product is installed in a humidity-controlled (<60% RH) environment where airborne contaminants and transients are controlled, and there is NOT a relay connection made to power mains.
