5.1.
AUTO ADDRESSING
The sounder base 4479 with detector 4400I supports automatic addressing via the EBLWin.
The sounder base 4479 has no short circuit isolator, which is necessary for automatic addressing. But in conjunction with 4400I,
auto addressing is possible.
To be able to auto-addressing a unit, the unit must have its default address.
The 4479 has address 255 as default. (The 4400I has address 0 as default.)
5.2.
MANUAL ADDRESSING
If auto addressing is not used, there is a possibility to manually set the address.
Each COM loop unit has to have a unique COM loop address (001-253).
Set the address with the Address Setting Tool (4414 / 4414E). Use the connection cable with crocodile clips to connect the SA & SB
terminals of the tool with the SA & SB terminals of the 4479.
The COM loop address and mode settings have to be done before the unit is connected to the COM loop.
The detector plugged in the base has to have a different COM loop address than the sounder base.
