C&H Technologies, Inc. <> 445 Round Rock West Drive <> Round Rock, TX 78681 <> www.chtech.com 1.0 GENERAL DESCRIPTION The M222 provides 4 individual Form C (SPDT) channels for general purpose switching and control of external devices on a single wide M-Module adhering to the ANSI/VITA 12-1996 specification for M-Modules. With its 5 ADC per channel current rating, it can be used to switch external power supplies. The module may be installed on any carrier board supporting the MModule specification.
1.2.2 Specifications C&H Technologies, Inc. <> 445 Round Rock West Drive <> Round Rock, TX 78681 <> www.chtech.com 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 userconnections back onto the carrier board. The user input/output is provided through a standard 44-pin D-subminiature female receptacle.
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. C&H Technologies, Inc. <> 445 Round Rock West Drive <> Round Rock, TX 78681 <> www.chtech.com 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.

2.0 INSTALLATION C&H Technologies, Inc. <> 445 Round Rock West Drive <> Round Rock, TX 78681 <> www.chtech.com 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.
2.4 PREPARATION FOR RESHIPMENT C&H Technologies, Inc. <> 445 Round Rock West Drive <> Round Rock, TX 78681 <> www.chtech.com 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.

Switching Schematic 3.1.1 M-Module Interface An M-Module interface allows communication between the M222 and the carrier module.
3.2 IDENTIFICATION AND CONFIGURATION REGISTERS 3.2.1 I/O Registers C&H Technologies, Inc. <> 445 Round Rock West Drive <> Round Rock, TX 78681 <> www.chtech.com 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. Table II.

This BUSY bit is re-triggerable. 2. Reading this register does not clear a pending interrupt (RIRQ). Reg.
3.2.2 Module Identification C&H Technologies, Inc. <> 445 Round Rock West Drive <> Round Rock, TX 78681 <> www.chtech.com 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. The PROM is compatible with a standard IC 9603 type PROM.
4.0 OPERATION C&H Technologies, Inc. <> 445 Round Rock West Drive <> Round Rock, TX 78681 <> www.chtech.com The M222 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.

C&H Technologies, Inc. <> 445 Round Rock West Drive <> Round Rock, TX 78681 <> www.chtech.com APPENDIX A: CONNECTORS MAXIMUM VOLTAGE/CURRENT: The 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.
