Setting Metasys N2 Address On Communication Adapter
Switches 1-8 on the adapter’s ‘B’ dipswitch are used to set the Metasys N2 node address.
Possible addresses are 1-255. Use the following technique to set switches B1-B8:
Divide the desired N2 address by 16. Take the integer part of the result (0-15) and use
the following table to set switches B1-B4:
N2 address upper half B1 B2 B3 B4
(N2 address lower half) (B5) (B6) (B7) (B8)
----------------- ----------------------------------------------
0 Off Off Off Off
1 Off Off Off On
2 Off Off On Off
3 Off Off On On
4 Off On Off Off
5 Off On Off On
6 Off On On Off
7 Off On On On
8 On Off Off Off
9 On Off Off On
10 On Off On Off
11 On Off On On
12 On On Off Off
13 On On Off On
14 On On On Off
15 On On On On
Take the value 0-15 from above and multiply that times 16. Subtract the result from the
desired N2 address. This gives another number 0-15. Use this number and the table to
set switches B5-B8.
Example: Desired N2 address is 35.
35 divided by 16 gives 2.1875.
Integer part of answer is 2.
Use table entry for ‘2’ to set B1=Off, B2=Off, B3=On, B4=Off.
Multiply 2 (from above) times 16 = 32.
Subtract 32 from desired address: 35-32 = 3.
Use table entry for ‘3’ to set B5=Off, B6=Off, B7=On, B8=On.
