The line numbers are represented by the top row in MAX and blocks 2
MicroMAX/MAX and the address numbers are represented by the bottom row of blocks in the MAX and

the four bottom blocks in the MicroMAX/MAX
this mode.
The combinations are shown in the following Figure:-
Address
The first digit of the two digit number refers to the line that the module is connected to ( Line 1 on the Galaxy
3-48; lines 1-2 on Galaxy 3-144; and lines 1–4 on the Galaxy 3-520); the second digit is the physical address
number of the MAX module. For example, a MAX module displaying as 25 indicates that the module is on
line 2 and is addressed as 5.
Pressing the # key gives a graphic representation of the MAX address in a binary format. The top two boxes
on the top row indicate the line address; the bottom four boxes indicate the physical address.
Descriptor
The descriptor is a maximum of 16 characters entered in the MAX Parameters option (63.2.3)
Engineer Mode
On accessing the Access Doors option in engineering mode, each on-line MAX module displays its address
by lighting the appropriate LEDs. To help the engineer identify each of the MAX modules, the keypad dis-
plays a graphic representation of the MAX module address. By matching the
image to the LEDs on the MAX, the engineer can identify each MAX module on the system.
