INTEGRATION GUIDELINES
The following guide is designed to provide the developer/integrator additional information
regarding hardware considerations. The sections include detailed design ideas along with tips
and tricks we have used in implementing various applications. Each section has a brief
description and diagrams to assist you in your planning stages with the CMM9900/CMM9920.
MOUNTING
The CMM9900/CMM9920 has four mounting holes arranged in the pattern shown in figure 1.
If stand-offs are to be used, metal type is the recommended due to added ground potential. In
figure 1, the stand-offs set the CMM9900/CMM9920 unit slightly higher than the host PCB. An
air gap is not necessary but will allow for PCB to PCB isolation and noise immunity. The
standoff used on the evaluation PCB is exaggerated to display the CMM9900/CMM9920. The
height of these stand-offs are not necessarily ideal and space can be greatly conserved by
using shorter ones.
Figure 2. Shows an example of a plate shield already used on an application with the
modification of bent tabs to allow for mounting of the CMM9900/CMM9920. This is a relatively
inexpensive method of mounting and can be implemented easily when the plate is initially
punched. Care should be taken so that the tabs do not extend past the flash area of the
mounting holes.
Figures 3 and 4. Shows the mechanical drawing of the CMM9900/CMM9920 units. These
dimensions should be used for mounting and placement purposes. The drawing is illustrated
from the bottom side perspective. The antenna and interface connectors are located on the
topside of the PCB.

ANTENNA CONSIDERATIONS
The diagrams below illustrate the different antenna selections used for applications. Each
example has implementation criteria due to its performance and operation.
A. The quarter wave antenna is small and lends itself well into tight applications where space is
critical. A ground plane radius of greater than 100mm is required for proper operation. Failure to
provide this grounding will result in erratic radiation patterns, signal loss and mismatched
impedance to the CMM9900/CMM9920.
B. The half wave antenna is twice the length of the quarter wave. It’s properties require less
ground plane which make it more ideal for applications that have less metal mass. The antenna
has a better radiation pattern.
C. The dipole antenna provides a ground-plane-free operation with optimum gain for its size.
This antenna provides its own ground-radiating element and can be used with plastic
enclosures.
WARNING
Use of antenna types other than those included on the CMM9900/9920 FCC
Equipment Authorizations may invalidate the FCC and PTCRB approvals
for this product. See the appendix in the back of this document for a
current list of approved antennas.

SHIELDING CONSIDERATIONS
When planning the PCB layout for an application some design rules and layout plans should be
considered. The following diagrams show various mounting configurations with respect to
shielding. Often the application PCB does not allow for separate ground plane implementation.
In these cases a list of design rules should be used in order to prevent inter-circuit problems.
The last section of this document deals with common design practices used with RF module
implementations.

RETROFIT INSTALLATION GUIDELINES
The CMM9900 and CMM9920 are designed to be ‘drop-in’ replacements for the legacy CMM
products. This means that no modification to the hardware or software of the application device
is necessary in order to install and operate the CMM99xx in place of the legacy CMM device.
(With the exception of the replacement of the CMM device, and possibly the antenna.)
There are however, some specific steps necessary in order to successfully complete the
process of installation into an existing application device. The following guidelines will describe
the process of installing the CMM9900 or CMM9920 into existing CMM-based applications:
NETWORK PROVISIONING OF THE CMM9900/CMM9920
The CMM9900 and CMM9920 must be provisioned for operation on the GSM network before
they access the network to send and receive data. The CMM99xx devices receive the majority
of their network provisioning information through the installation of a GSM SIM card onto the
module. The installation of the SIM card onto the CMM99xx module must be completed prior to
installation of the module into the application device.
There is also additional information that must be provided to the module in order to finalize the
provisioning process and allow communication of data through the Control Channel Network
Server via SMS and/or GPRS. This information may include some or all of the following:
• Original Primary MIN number
• Any secondary MIN number(s) used
• Electronic Serial Number(ESN) of original CMM module
• SMS address for Control Channel Network Server
• Control Channel Network Server IP address for GPRS data
• APN for GPRS data
Default values for SMS address, Control Channel Network Server IP address, and APN are preloaded into the device based upon the type of Control Channel Network at time of installation
configuration. These values may updated manually via the serial interface or over-the-air if they
require changes in the future.

CalAmp Integration Guide
AMPS Retrofit Converter CMM9900/CMM9920
COPYING THE CONFIGURATION INFORMATION FROM THE ORIGINAL DEVICE
The configuration information from the original CMM device is necessary for the CMM99xx to
properly communicate the data back to the network server and function transparently.
Refer to the Sections following for specific information regarding removal, installation and
validation.
REMOVING THE ORIGINAL CMM DEVICE
The original CMM device should be removed using procedures appropriate for the specific
application device. Power should always be removed from both the application device and the
CMM device prior to conducting any installation, or removal of the CMM device.
Special care should be taken not to damage the application unit or the original CMM device.
(Further operation of the original CMM module may be required in order to copy the
configuration data for loading onto the new CMM99xx module.)
WARNING
Precautions must be taken whenever handling the CMM to protect the electronic circuitry of
both the CMM module and the application device from damage due to static discharge (ESD).
INSTALLING THE CMM99xx RETROFIT ADAPTER
The CMM99xx device should be installed using procedures appropriate for the specific
application device. This will normally be the same, or very similar, procedure to that used for
installation of the original CMM device.
If the existing antenna connected to the application device is not an approved antenna, it should
be removed and replaced with an approved antenna prior to re-applying power to the unit.
VALIDATING THE INSTALLATION
Validation of the CMM99xx installation should be conducted to confirm successful installation of
the device and that the application device is still functioning properly. Validation testing should
also confirm that all necessary configuration and identity information has been programmed into
the CMM99xx device.

CMM99xx approval files. Use of an unapproved antenna system in the end application
will make these approvals invalid in that application. Applications requiring the use of an
antenna system not currently on the approved list will require either (1) Re-testing and
updated approvals to add that antenna to the CMM9900 list of approved antenna
systems; or (2) New approvals under the customer name.
PART 15 CERTIFICATION
The CMM9900 and CMM9920 have been certified to meet the requirements of Part 15 of the
FCC Rules as a Class B device. This certification only applies to the CMM99xx unit itself. Once
installed into an application device, responsibility for Part 15 compliance becomes the
responsibility of the manufacturer/provider of the end-product (application).
The environment within the application device includes other potential sources of radio
frequency (RF) interference in addition to the CMM99xx. These potential sources include such
items as crystal oscillator(s), digital address/data lines, switching power supplies, and other
circuitry.
All application devices subject to Part 15 of the FCC rules must be retested and certified to be in
compliance with the rules. This retesting and certification is the responsibility of the customer.
