12-6. Assigning unit numbers in the Easy-link system
A.
How to display the unit number
Press the “Increase” button on the computer board. The 7-seg LED will then display the assigned
number for that T-D2-IN or T-D2-OS unit for 10 sec.
NOTE: In a single-unit installation, the numbering system is disabled.
B. How to reset and reconfigure the numbering of units
Unit #’s can be reset and reassigned manually:
1. Press and hold the “Increase” button on the computer board of all child units for at least 5
seconds.
2. The 7-seg LED on the computer board of all child units will display “0” to signify that the computer
memory has been erased of its previously assigned unit #.
3. Press and hold the "Increase" button on each unit in the new order of your choosing. The new
unit numbers will be assigned in this order.
Each T-D2-IN or T-D2-OS in an Easy-link system is assigned a random unit #,
except for the
Parent unit, which is always assigned as unit #1.
When more than four units of the T-D2-IN or T-D2-OS are connected in an
Easy-link system, only the first four units will work as a system. The
remaining units will not operate.
