LED Status
When the access doors option is entered in engineering mode the MAX address can be displayed by pressing
the # key. This feature includes displaying the MicroMAX address using the MicroMAX LED format. This is
shown in the following Figure graphically for both a MAX and a MicroMAX address as 26.
Figure 1. LED Status
The line numbers are represented by the top row in MAX and blocks 2
nd
and 3
rd
from the top in the
MicroMAX and the address numbers are represented by the bottom row of blocks in the MAX and the four
bottom blocks in the MicroMAX. The top LED on the MicroMAX is always off in this mode.
The combinations are shown in the following Figure:-
Figure 2. Line Number/Module Address
Address
The first digit of the two digit number refers to the line that the module is connected to (line 1 on Galaxy 18 &
60, lines 1-2 on Galaxy 128, and lines 1–4 on the Galaxy 500, 504 & 512); 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 (LED off) and (LED on)
image to the LEDs on the MAX, the engineer can identify each MAX module on the system.
