ADDRESSING THE RTU
The RTU is DIP switch addressable from 1 to 255. This is done by using the 8-position DIP
switch labeled SW1. Position #1 is the LSB and position #8 is the MSB. All switches off
corresponds to 0, and all switches on is 255. The count is binary:
#1
1
#2
2
#3
4
#4
8
#5
16
#6
32
#7
64
#8
128
Each unit on a system must have a different ID in order to respond.
Examples:
1 2 3 4 5 6 7 8
ON
OFF
The configuration above would define this unit as #3: 1 + 2 = 3
1 2 3 4 5 6 7 8
ON
OFF
The configuration above would define this unit as #26: 2 + 8 + 16 = 26
Note
The RTU may be given an address greater than 255 by changing the address
extension through the configuration menus. See “Address Extension” on page 11.
