6. Setting the Metasys N2 Address on the Communications Adapter Board
Switches 1-8 on the adapter’s ‘B’ DIP switch are used to set the Metasys N2 node address. Possible addresses
are 1-255. Use the following technique to set switches B1-B8.
Step
Description
1.
Divide the desired N2 address by 16.
2.
Take the integer part of the result (0-15) and use the following table to set switches B1-B4.

3.
Take the value 0-15 from above and multiply that times 16.
4.
Subtract the result from the desired N2 address.
5.
This gives another number 0-15. Use this number and the table to set switches B5-B8.

Example:
Desired N2 address:
35
Divide by 16:
(35
÷
16) = 2.1875
Integer part of answer:
2
Use table entry for ‘2’ to set B1-B4:
B1=Off B2=Off B3=On B4=Off
Multiply 2 (from above) by 16:
(2 x 16) = 32
Subtract result (32) from desired address: (35-32) = 3
Use table entry for ‘3’ to set B5-B8:
B5=Off B6=Off B7=On B8=On
