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.
2.2 HANDLING PRECAUTIONS
The module contains components that are sensitive to electrostatic discharge. When handling the
module for any reason, do so at a static-controlled workstation, whenever possible. At a
minimum, avoid work areas that are potential static sources, such as carpeted areas. Avoid
unnecessary contact with the components on the module.
2.3 INSTALLATION OF M/MA MODULES
All M-Modules must be installed into the carrier before the carrier is installed into the host
system. To install a module, firmly press the connector on the M/MA-Module together with the
connector on the carrier as shown in Figure 1. Secure the module through the holes in the bottom
shield using the original screws.
CAUTION: M/MA-Module connectors are NOT keyed. Use extra caution
to avoid misalignment. Applying power to a misaligned
module can damage the M/MA-Module and carrier.

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. If the module was received
separately from a C&H system, then the original module shipping container and packing material
may be re-used if it is still in good condition.

3.1.1 M-Module Interface
The M-Module Interface allows communication between the M220 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.
3.1.2 Module Control
This block contains all of the logic for the module including all registers, interrupt control and
carrier interface.
C&H Technologies, Inc. <> 445 Round Rock West Drive <> Round Rock, Texas 78681 <> www.chtech.com

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 usesa 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.
The Row Driver block translates the ROW_SET(4:1) and ROW_RESET(4:1) command lines
from the Module Control block into bipolar and tri-state capable buffered drive signals. The
ROW_DR(4:1) signals provide either current source from the +5VDR supply (relay set), current
sink to ground (relay reset), or tri-stated output (both current-source and current-sink off). Each
output is tri-stated whenever that particular row is not being driven.
The Column Driver block translates the COL(4:1) command lines from Module Control into the
bipolar buffered drive signals, COL_DR(4:1). The COL_DR(4:1) signals provide either current
source from the +5VDR supply (relay reset) or current sink to ground (relay set).
3.1.5 Driver Power Switch
This block removes all power from the Row and Column Driver circuitry except when needed to
move relays. This FET switch is open at power-up to prevent any relay contact movement until
register writes cause drive-power to be applied.
3.1.7 Relay Coils
This block contains the 16 relay coils arranged as a 4x4 matrix. To close a relay, a ROW_DR line
sources current while a COL_DR line sinks current to ground. To open a relay, a COL_DR line
sources current while a ROW_DR line sinks current to ground. Refer to Figure 3 for switching
schematic.
3.1.8 Reset and Power Conditioning
This block filters +5V power to produce VCC power (+5V) for logic and isolates the various
grounds used by the module. This block also processes the /RESET signal fromthe Carrier
Interface and monitors power to produce the /RST reset signal for the module.

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). If
you need to change this jumper position, it must be done before installing the M-Module onto the
carrier.

3.2.3 Module Identification
The M220 supportsthe 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. Data should
not be written to the PROM.
The module also supportsthe VXI-IDENT function. This function is not part of the approved
ANSI/VITA 12-1996 standard. This extension to the M-module IDENT function increases the
size of the PROM to 64 words and includes VXI compatible ID and Device Type Registers.
Details are shown in Table III.
