Information for Your Safety

Please read these safety instructions and the operation instructions
provided in this manual before operating the modem or the battery
charger.

SAR (RF Absorption Levels into body)

Your modem contains a low power transmitter and receiver. When it is
switched on, it receives and sends out radio frequency (RF) signals. In
August 1996, the Federal Communications Commission (FCC)
adopted RF exposure (SAR) guidelines with safety levels for handheld
wireless devices. These guidelines are consistent with safety standards
previously set by both USA and International Standards: ANSI C95.1
(1992), NCRP Report 89 (1986), ICNIP (1996).

The modem is designed for handheld operation and has been certified
to comply with the aforementioned FCC guidelines and standards
under worst case conditions (zero separation distance). To maintain
the optimum operational characteristics, no part of the human body
should be in contact with the antenna during use.

Getting Started

Setting up the Modem and iPAQ

Before using your non-rugged PRM240i modem, you must:

Install the modem software onto your iPAQ Pocket PC



 Fit the external battery to the modem

Engage the iPAQ Pocket PC onto the modem



 Fully charge the modem and iPAQ batteries

PRM240i Modem Software Overview

Included on the CD-ROM are the modem device drivers and Modem
Info user application software. These are contained within three CAB
files, which need to be installed on the iPAQ Pocket PC, namely:

 DWiUART.ppc30_arm.CAB

DWiVDD.ppc30_arm.CAB



 MSMQ.ppc30_arm.CAB

DWiUART.ppc30_arm.CAB

This CAB file contains the low level drivers that instantly create a
serial communications port to the non-rugged PRM240i modem upon
every iPAQ insertion into the modem sleeve. These drivers must be
installed to enable access to the non-rugged PRM240i modem for any
application software. This CAB file also contains a basic programmer’s
interface for third party application developers who should refer to
document “DWI Modem Device Driver” (DWI10006WTxx) for
further information.

DWiVDD.ppc30_arm.CAB

This CAB file contains the non-rugged PRM240i Virtual Device
Driver, Port Server and Modem Info application.

Modem Info is a graphical user interface modem diagnostic and
information tool to enable you to:

Check the network connection status and modem parameters



 Check the modem hardware and battery status

Set the various operating modes of the modem



 Register third party applications for invocation on specific

modem events

Modem Info is supplied in both executable and source code form as an
example for iPAQ application developers to communicate with the
non-rugged PRM240i modem.

68P80802E60-O 13 Motorola

Care & Maintenance ____________________________________________ PRM240i Wireless Modem User Manual

The Virtual Device Driver (VDD) and Port Server are essentially
“middleware” software, which provides a layer of abstraction to
application developers so that communications with the modem can be
significantly simplified. They remove the requirement to fully
understand the Native Communication Language (NCL) syntax to
communicate with the modem.

In addition, the VDD and Port Server allows multiple applications (or
“sessions”) on the iPAQ Pocket PC to simultaneously interface with
different network host servers, such as an email client, web browser,
dispatch application or Modem Info itself. Messages are routed to the
appropriate application via the Microsoft Message Queue facility.
Third party application developers should refer to document “DWI
Modem Virtual Device Driver and Application Interface”
(DWI10010WTxx) for further information.

If multi-session capability is not required, the VDD and Port Server
CAB file does not need to be installed, however, Modem Info requires
this middleware software in order to operate.

MSMQ.ppc30_arm.CAB

The Microsoft Message Queue (MSMQ) allows multiple applications
(or sessions) to simultaneously utilize the single non-rugged PRM240i
modem in which an iPAQ is inserted. It is the mechanism by which
information is routed between the appropriate application on the iPAQ
Pocket PC and the network host server.

Installing the Modem Software

To install the CAB files onto your iPAQ, ensure that the iPAQ desktop
software has been installed on your computer first and then use the
following procedure.

Using Your PRM240i Modem

Switching the Modem On/Off

The non-rugged PRM240i modem does not contain a manual on/off
power switch. The modem is automatically powered on/off when the
iPAQ Pocket PC is inserted and removed respectively.

Before operating your non-rugged PRM240i modem ensure the battery
is fully charged, Modem Info software has been installed on the iPAQ
and the iPAQ is inserted into the modem, as described earlier.

Upon first iPAQ insertion the modem Power/On-Line indicator should
display slow flashing green (once per second) as the modem searches
for a network connection. As soon as the modem is registered the
Power/On-Line indicator will fully illuminate. If network access is
denied or no network can be found the Power/On-Line indication will
continue to search to flash until it can register somewhere. On
subsequent insertions the Power/On-Line indicator will reflect the

Setup Tab

This tab displays the following information about the modem attached
to the iPAQ:

Power Mode

There are four power modes available;

ON (modem only) – The modem is on and the
battery is exclusively used by the modem

Battery Sharing – The modem is on but the
modem battery is “shared” with the iPAQ to
extend the iPAQ operating time. In order to
share this capacity the modem periodically
trickle charges the iPAQ when the voltage is
lower than the modem battery by a certain
threshold. Trickle charging is inhibited when
the modem battery voltage falls below 3.7V.

Battery Extended – The modem is off
(actually in a very low power mode) and the
modem battery is exclusively used by the iPAQ
through the trickle charge mechanism described
previously.

OFF (No battery sharing) – The modem is off
(actually in a very low power mode) and access
to the modem battery is disabled.

Applications Tab

This tab displays a list of Registered Applications on your iPAQ that
are registered for wakeup

If desired, register those applications that need to be invoked when the
modem receives an incoming message and/or when the iPAQ is
inserted into the non-rugged PRM240i modem. Up to eight
applications can be registered for wakeup. To register an application,
tab onto a blank edit box, fill in the full path of an application and
check one or both of the associated check boxes. To deregister simply
ensure both check boxes are unchecked and/or delete the contents of
the associated edit box.

In the example shown, the Modem Info application will be
automatically invoked the next time the iPAQ is inserted into the
modem.

The Registered Server edit box lists the full path of the server
application. This application is invoked when the iPAQ is inserted into
the modem. It runs in the background, allowing multiple client
applications (like Modem Info) concurrent use of the non-rugged
PRM240i modem. If you want to run an application that requires
exclusive use of the modem, deregister the server application by
deleting the contents of the edit box and re-attach the modem.

Troubleshooting

If you encounter a problem with your modem or battery charger,
review the following list of frequently asked questions.

I’m getting no response from the modem.

Make sure that the iPAQ is fully inserted into the modem, the
ModemInfo application has power setting is on and the modem is fully
charged. The Power/On-Line indicator should be illuminated and Low­Battery indicator off.

Select the Modem Info application from your iPAQ’s main screen to
display the Modem Info screen. Check the battery indicator is showing
adequate battery charge status.

Battery Charge
Capacity is
shown here

Refer to page 21 for information on charging your modem.

The Power/On-Line Indicator is continually flashing green.

The Power/On-Line indicator should fully illuminate when connected
with the network. Also check the RSSI signal level in the ModemInfo
application. It should be greater than –110dBm.

Care & Maintenance ____________________________________________ PRM240i Wireless Modem User Manual

I’m having difficulty sending and receiving messages. The Online
indicator fluctuates between on and flashing.

Fluctuation in signal strength can happen in fringe areas on densely
populated areas with tall building. When operating in an area of low
signal strength, the modem may go on and off line as the signal
fluctuates above and below the minimum user level.

Check that you are in an area that provides coverage. Your network
provider should have the details.

The modem may also temporarily go off line and back on as it roams
from one frequency to another in order to obtain improved coverage
per normal network operation.

What can I do to get back in range?

The wireless signal needs a clear path; avoid congested or metal
buildings or tunnels. Tree leaves and windows may also affect the
signal strength, as can environmental conditions, for example heavy
rain. Try moving away from buildings and hold the device away from
your body.

The status shows that I’m in range, but I’m still having difficulty
sending and receiving messages.

Check the battery level as low battery levels can affect the connection.
Select the Modem Info application from your iPAQ’s main screen to
display the Modem Info screen. Check the battery indicator and
compare it with the examples below.

How can I extend battery life?

You can extend battery life by:

 Turning off the modem when you are not using it.

Selecting the Maximum Power Save option from the Modem



Info Setup tab if your network operator supports this feature.

Does a weak RF signal affect battery life?

The battery usage estimates assume that the modem is switched on
between eight to ten hours a day and you are located in a good RF area.
The life of the battery charge may be considerably less if you are
operating your modem in a weak RF area.

Can I still receive messages when the iPAQ and modem is charging?

Yes, messages can be sent and received when the iPAQ and modem
batteries are charging.
