3. Application Illumination
3.1 Mirror Display Function
With this function, weighing data can be displayed in reversed
format to suit special requirement.
Push SW2 switch （ blue switch ） D1 to
ON, Then power on again, weighing data
will be displayed in reversed format.
3.2 Communication Address Setting
Through D3 、 D4 、 D5 、 D6 of SW2 switch (blue switch) to set
communication address, after setting, power on again. Near
number side is defined 0, and near “ON” side is defined 1. Please
restart GM8895 to make new setting effect. The address table:
D3 D4 D5 D6 Display
Address
0 0 0 0 0
0 0 0 1 1
0 0 1 0 2
… … … … …
1 1 1 1 15
For example: If present SW2 switches
are same as right Diagram, the current
remote Display address is “3”.
When Remote Display address is “0”, it works in single
communication mode, and address is meaningless for
communication; while the address is not “0”, it works in multiple
communication mode, and address should be matched when
communication.
