Introduction[top]
-
-
This document is designed as a step-by-step guide to help you connect your
Visor to your Ericsson SH888/I888 mobile phone (or other models attached
with DI27 infrared modem) for internet connection (email, faxing, or web
browsing.) It is worth noting that other settings may also work and
that the settings described in this document are being used as a means
to get you up and running with the least amount of hassle. Furthermore,
this document assumes you have installed:
-
IrLink v1.5 or later
SerIrCommLib.prc
extracted from 3Com's IR Enhanced Update
-
Note: If you haven't installed IrLink or 3Com's IR Enhanced Update, click
here to go to the IrLink
installation instructions.
1. SH888/I888
mobile phone/DI27 setup [top]
-
Verify that your SIM card is enabled for data/fax – if you are unsure,
contact your network provider, who will be able to enable your SIM if necessary.
-
If necessary, ‘activate’ the Infrared port on the mobile phone (see note
1)
-
Position both units so that the Infrared ports line up at a distance of
between 6 to 10 inches (15 to 26 CM) and at a 20 to 30 degree angle.
-
For best results you should avoid bright light sources.
-
For best results your mobile needs to be displaying a good signal strength
(2 to 4 bars on your mobile display window). Note: This
is network dependent on your cellular provider in your coverage area.
Failure to have a good signal strength may lead to intermittent dropped
calls.
Please Note
-
To ‘activate’ the Infrared port on the Ericsson SH888, use the two-left/right
arrow keys between the yes/no buttons on the phone keyboard to enter the
menu system. Scroll to 'Activate IR port' and press YES. (If the IR port
is already activated, the display will read 'Deactivate IR port' instead.
In this case, just press CLR to return to the standby menu.)
-
For a few seconds the text 'IR port activated' will appear in the display.
The phone then returns to standby mode.
-
A wireless connection is liable to open air effects, which means that any
call over GSM will not be as reliable or as fast as a land line to cable
modem setup.
-
Expect success rates of about 70% for faxing and 90-100% for connecting
to the Internet over the GSM network. These figures are network and
coverage dependent for your area of use.
-
You will not be able to receive a fax call over your mobile phone without
first knowing your mobile’s fax number – please check with your network
provider regarding this. NOTE: Your mobile’s fax number is NOT the
same as your mobile’s voice number.
-
If you are attempting to receive a fax call, your phone will tell you what
type of call you are receiving. If it does not say “Fax Call” then you
are not receiving a fax call.
-
If you experience any problems, deactivate any HackMaster extension that
will affect the CPU clock.
-
When a program is designed for cradle communication, it may fail
on IR connection due to the long CPU withholding. IrDA on Visor is
very sensitive to timing. It will drop the connection if the IR signal
is not maintained in a timely fashion.
2. Visor
Modem Preference setup [top]
-
Run Prefs Application (Preference setup) from Application Launcher
-
Select Modem from the Preference drop down menu
-
Modem setup parameters:
Modem: Custom
Speed: 9600
Speaker: Low
Flow Ctl: Automatic
String: AT&F
Note: You may not see the Custom modem type. Once you change
the String content, the Custom modem type will appear automatically.
3.
Visor Network Preference setup [top]
-
Run Prefs Application (Preference setup) from Application Launcher
-
Select Network from the Preference drop down menu
-
Choose the name of your ISP on "Service" or create a new one by selecting
New from the Service Menu
-
Input your account name
-
Input your password or you will be prompted when you try to connect to
your ISP
-
Input the phone number of your service provider
-
Tap the Details to setup network related items. This setup depends
on the service that you use to connect to the internet. Most likely
you will use PPP, Idle time-out: Power Off, Query DNS: checked, IP Address:
Automatic checked, and no script is required.
-
If you get PPP time-out or PPP authentication error, you have the
wrong setup or script for your service provider. Please check with
your ISP for proper setup.
4. Connect Visor
to SH888/I888/DI27[top]
-
Launch IrLink
-
Make sure IrLink is set to IrDA 1.0
-
Tap the Net Panel bitmap (not the label) to go to the Network Panel
-
Activate the IR port of your SH888/I888. (IR of DI27 is always on)
-
Tap the Connect button to initiate the network dial-up
-
Once the network is up, tap the Done button to go back to the IrLink
-
You can than launch your email/browser application
Tips:
-
The fail ratio of Visor to SH888/I888 Infrared Connection varies depending
on your GSM service region and manufacturing batch of SH888/I888.
Practice is very important.
-
Try to avoid a bright light source.
Please Note
-
If the phone drops the call and the software still says you are connected,
ensure that you have told the software you have disconnected. Otherwise
if you try to change the settings the software may get confused and reset
some settings to their default.
-
Avoid future login problems by closing down your connection to the email/web
post office properly; i.e. Select the Pref/Network ‘Disconnect’ or disconnect
feature your application is providing.
5. Troubleshooting
[top]
The following method can be used to check that your Visor can establish
a link with the Infrared modem being used.
-
If you feel the IR port is not behaving normally on the mobile phone, reset
the mobile phone.
-
If you feel the IR port is not behaving normally on the Visor, soft reset
the Visor.
-
Check that the Infrared port is activated on the mobile phone.
-
If necessary, use the "IrDA Device Discovery" feature in IrLink to make
sure the IR device of your Visor or mobile phone is working normally.
-
You can use a Terminal Emulator to check your SH888/DI27 modem by typing
‘ati’ and press return. You should receive a prompt of either “Ericsson
SH 888 Infrared Modem” or “Ericsson DI 27 Infrared Modem” followed by an
‘OK’ when the interface between Visor and mobile phone is working correctly.
-
If you get Error 501-- Modem not found, please make sure the IrLink
is set to IrDA 1.0 and IR port on SH888 is activated.
-
If you get Error 1102 -- no carrier, most likely you don't have the data
service activated. Please check with your GSM carrier for the service
options.
