6.6 Testing on HP8922
NB* To test the PCB on its own without a housing or SIM card the unit must first be put into test mode and then
into Tx or Rx mode using the applicable manual test commands. Ensure that a battery is present during this, as the
battery acts as a SIM card presence detect for the unit. The PCB can then be taken out of the housing for any
analysis.
6.7 Testing IrDA Port
To test the IrDA port the following set up should be followed, the distance between handset and IrDA port should
be less than 30cm and although accurate alignment is not neccesary the two should be lined up as well as possible.
Note. Software is required for both the L7082 / L7089 IrDA link and also the host IrDA port.
A CD Rom will be shipped with the unit to enable data transfer, the drivers for the host IrDA device should be
supplied with the device. For testing all we are looking for is the discovery frame between PC and handset.
•
Please note this set up can only be used for Data Transfer not
Flashing or Flexing.
Also,Windows NT does not have the drivers to support IrDA
