Communication between the SSC, ECM and XM2s takes place through
the RS-485 Alpha Bus.
To set power supply addresses (Refer to section 2.4, “Smart Display
Setup Menu for more information”):
1. Beginning at the Normal Operations menu of the LCD on the
power supply, press the ENTER key twice. This brings the user
into an Auto-Scroll Setup menu.
2. Look for the Parameter named DEVICE ADDRESS.
3. Press the ENTER key to select the item for editing.
4. Use the UP arrow key to increase the displayed value, or the
DOWN arrow key to decrease the value. Pressing and holding
either the UP or DOWN arrow keys for more than two seconds
while in edit mode will change the value more quickly.
• Set address of each power supply in valid range, defined as
1-6.
• The SSC will not recognize any power supply with address 0,
or any address greater than 6. Other addresses will
generate the configuration alarm and be ignored.
• The unit that is given the lowest device address is identified
as the master XM2. The master XM2 is used for system
programming, and controls the remaining XM2s in the
system. (The master XM2 does not need to be the unit that
houses the SSC.)
5. Press the ENTER key when the desired value is displayed. This
will access an additional display, which gives the operator a
chance to back out of the programming mode (ESCAPE), and not
save the new value, or to accept and save the new value into
memory by pressing the ENTER key.
Note: XM2 device addresses must be set for the SSC to
function, and XM2 Software must be version 3.01 or
later.
