HGM-MZ to N2 Communications Adapter
6 Rev 1 (P/N 3015-5514)
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.
N2 Address
Upper Half
B1 B2 B3 B4
N2 Address
Upper Half
B1 B2 B3 B4
0 Off Off Off Off 8 On Off Off Off
1 Off Off Off On 9 On Off Off On
2 Off Off On Off 10 On Off On Off
3 Off Off On On 11 On Off On On
4 Off On Off Off 12 On On Off Off
5 Off On Off On 13 On On Off On
6 Off On On Off 14 On On On Off
7 Off On On On 15 On On On On
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.

0 Off Off Off Off 8 On Off Off Off
1 Off Off Off On 9 On Off Off On
2 Off Off On Off 10 On Off On Off
3 Off Off On On 11 On Off On On
4 Off On Off Off 12 On On Off Off
5 Off On Off On 13 On On Off On
6 Off On On Off 14 On On On Off
7 Off On On On 15 On On On On
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
