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] Please Note
    1. 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.)
    2. For a few seconds the text 'IR port activated' will appear in the display. The phone then returns to standby mode.
    3. 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.
    4. 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.
    5. 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.
    6. 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.
    7. If you experience any problems, deactivate any HackMaster extension that will affect the CPU clock.
    8. 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.
