Setting the address
The A50E-2 Line Relay Unit contains a seven-segment DIP
switch. The switch is used to set the device address in binary
code. The switch may be set to represent any address from 1
to 127.
In the ON position, a switch represents its code value. In the
OFF position it represents a zero. See the table below.

To arrive at the address number of a device, add the code
values of all switches that are in the ON position, for example
switches 2, 3, and 6 set to ON represent address 38 (2 + 4
+ 32).
