Page 7: General Description
Module specification. Carriers are available that allow the module to be used in Ethernet (LXI), VXI, VME, PCI, cPCI, PXI and other system architectures. 1.1 PURPOSE OF EQUIPMENT The M222 can connect multiple instruments to multiple points in your test system. This provides flexible interconnection between test points, instrumentation, factory automation, and test fixtures. -
Page 8: Specifications
1.2.2 Specifications The M222 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. -
Page 13: Functional Description
= Comm on 3.1.1 M-Module Interface An M-Module interface allows communication between the M222 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. -
Page 14: 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 M222 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 3. -
Page 15: Figure 3. I/O Registers
Reg. 00 Write Read Not Used BUSY Relay Busy (0 = relay is busy, not stable yet (busy for 16mS after Relay Register is written)) RIRQ Relay Interrupt (1 = interrupt pending) Notes: 1. This BUSY bit is re-triggerable. 2. -
Page 16: Module Identification
3.2.2 Module Identification The M222 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 17: Operation
Figure 4. Effects of Opening/Closing Relay 4.2 INTERRUPTS The M222 can generate an interrupt request 16ms after a relay is opened or closed indicating that the relay has settled. The interrupt must be enabled in the Control Register (Reg. 0x02). -
Page 19: Appendix A: Connectors
APPENDIX A: CONNECTORS MAXIMUM voltage that may be applied to any connector on the M222 is 125 VDC, 141 VAC rms, or 200 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. - Page 21 N O T E S:...
