INTRODUCTION This manual describes the operation and use of the C&H Model M220 Dual 8x1 Multiplexer MModule (Part Number 11029550). This module was formerly manufactured by HP (Agilent) as Model E2272A. C&H obtained the manufacturing rights from Agilent and now manufacturers it as C&H Model M220. This mezzanine module is designed to interface within any M/MA-Module carrier adhering to the ANSI/VITA 12-1996 M-Module specification.

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 MModules. The M220 may be installed on any carrier board supporting the M-Module specification. Carriers are available that allow the M220 to be used in Ethernet, VXI, VME, PCI, cPCI and other system architectures.
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 userconnections 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). CONEC part number 302A10889X (or equivalent) is used on the assembly.
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. The module also supports the optional IDENT and VXI-IDENT functions.

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. If damage exists, report immediately to C&H.
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. An on-board timer (part of Module Control block) ensures the relay coils have been driven long enough for the contacts to move and settle.

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. The M220 leaves the factory with the jumper placed in position A (dual 8-to-1 multiplexer).
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.

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. The PROM is compatible with a standard IC 9603 type PROM. For specific timing information refer to the 9603 or compatible PROM data sheet.
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. Refer to the carrier’s documentation for information on the address mapping of an MModule’s I/O registers and to your system software documentation for details on data access.
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. 4. When the module loses power, any closed relays remain closed (latching relays). When power is restored, the relays remain closed but the Row n Set and Row n Reset registers have lost their relay state information.
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. If four rows were instructed to move (four writes to the FIFO--see note below), then the module asserts an interrupt only after the completion of the fourth operation.

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. If these conditions CANNOT be maintained, then the maximum voltage is 60 VDC, 48 VAC-rms or 68 VAC-peak.
