The valid range of addresses is from 1 to 9999, although ‘base 10' values will be
automatically skipped. Edit the address of this SLAVE unit by selecting the digit to be
edited, using the
! " arrow keys. The value of the digit is then changed using the #$
arrow keys, then pressing
ENTER
.
Remember that this is a unit that is intended to be located at the distant-
end of a link, and will therefore be under the control of a MASTER at the
other end. This is the equivalent of putting the unit into Remote Control
mode - no local control is possible.
