Installing the Modem
This section will help you to successfully integrate the Boomer-III
OEM Modem into your custom application.
When integrating a wireless modem, internal connections and
placements are critical to a successful implementation. Specific
attention must be paid to the following support mechanisms:
 Mechanical mounting
 Serial interface and control
 Antenna connection
 Regulated power supply
 Application software
 Desense control
The OEM wireless modem is well suited for mobile or fixed
applications. Ruggedised and capable of operating in extreme
environments, the modem can provide communications for a wide
variety of products.
Handheld Portable Terminal Use
Without question, handheld designs produce the most hostile
environment for an integrated modem. A handheld device, such as a
portable terminal, is typically battery powered, subjected to
temperature extremes, and designed to be physically robust.
When designing portable devices, you must consider the following
issues:
 DC power noise levels on the host/terminal interface
 Minimum operating voltage levels
 Shutdown procedures
 Device internal ambient temperature
 Antenna gain and proximity to user
 Repair and reprogramming facilities (pass-through mode of
operation)
 Mechanical design for drop, vibration, dust, salt, and liquid spill
Note: Regarding the mechanical design, the Boomer-III OEM modem
is designed assuming that the host/terminal controls these conditions.
Fixed Mount Usage
Fixed-mount usage eliminates most of the mechanical constraints of
handheld designs, although the requirements still apply. Fixed-mount
units are sometimes AC-line powered and require filtering to eliminate
the 50Hz or 60Hz noise that can impair modem operation, depending
upon country of use.
