Page 7: General Description
Ethernet, VXI, VME, PCI, cPCI and other system architectures. 1.1 PURPOSE OF EQUIPMENT The M218 is a general purpose relay switch that can be used to connect test points on a device under test to instrumentation or to switch factory automation and fixturing. -
Page 8: Specifications
1.2.2 Specifications The M218 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 10 C&H Technologies, Inc. <> 445 Round Rock West Drive <> Round Rock, Texas 78681 <> www.chtech.com...

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. -
Page 13: Functional Description
Figure 2. M218 Functional Block Diagram 3.1.1 M-Module Interface The M-Module Interface allows communication between the M218 and the carrier module. The interface is an asynchronous 16-bit data bus with interrupt capabilities. The interface adheres to the ANSI/VITA 12-1996 Standard for The Mezzanine Concept M-Module Specification for MA modules. -

3.1.3 ID EEPROM The EEPROM holds sixty-four 16-bit words of M-Module ID data and VXI M-Module data. Refer to “ID EEPROM Register” on page 10 for EEPROM contents. 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. -

Page 16: Identification And Configuration Registers
3.2 IDENTIFICATION AND CONFIGURATION REGISTERS 3.2.1 I/O Registers There are a variety of registers used to configure and control the 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 4. -

For example, to close the Channel 04 relay on the M218 (Row 1, Column 0 in relay drive scheme) place a logic “1” in bit 00 of the Row 1 Set register.

Page 19: Module Identification
3.2.2 Module Identification The M218 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 20: Operation
4.0 OPERATION The M218 is a register-based instrument that is controlled through a series of I/O registers described in Section 3.2.1. 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. -

Matrix Drive... - Page 22 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 23: Appendix A: Connectors
APPENDIX A: CONNECTORS MAXIMUM VOLTAGE/CURRENT. The maximum voltage that may be applied to any connector on the M218, M219, or 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%... - Page 24 C&H Technologies, Inc. <> 445 Round Rock West Drive <> Round Rock, Texas 78681 <> www.chtech.com...
