External Testing

The G600 unit can be connected to a compatible personal computer for electronic adjustment and fault diagnosis.
This section provides a description of the equipment required to perform those tasks.
Testing and adjustment of the handheld unit can be performed with the outer case in place. For in-depth fault
finding the unit should be disassembled (section 5), and the extended card used to connect the PCBs together
externally as they would be found in normal use. Fault tracing can then be performed on the PCBs using suitable
test equipment, such as spectrum analysers and oscilloscopes.

Test Equipment Descriptions
1. Interface box, Part No. IFB002 (Figure 1)
The IFB002 provides:
a) Voltage regulation for +7.2V, +5.6V or 4.8V DC outputs. The +7.2V switch setting is used as a supply to Li-
Ion type batteries, the 5.6V switch setting is used for PCB testing and the 4.8V switch setting is used for testing
the complete unit.
b) RS 232 interface. Ensures that the Unit Under Test is supplied with the correct signal levels and format.

2. Personal Computer (PC)
The PC (IBM compatible) is used as a Unit Under Test controller. This in conjunction with the channel box
software, allows all of the test facilities normally provided through the keypad of the Unit Under Test.
3. Power Supply (not shown - see complete unit test setup)
Provides 12V DC supply to the Interface Box IFB002
