System configuration
Note:
14/30
If the address entered at the master unit matches with the slave unit then the selected slave
unit can be configured for display, or else “Address Mismatch” is displayed on the LCD and a
new address entry is requested.

Figure 8.
R is the termination resistance used for impedance matching.
Step 13: when the address is matched, the master control unit sends commands to the
selected slave control unit. The slave control unit processes these commands and
configures the display panel to display the entered data. The other slave units continue
to display the old data.
Step 14: press Esc to exit the present mode; after this, the system resumes from Step
9. If the new address entered (for slave selection) matches with the slave address then
the slave display is interrupted, or else the display continues with the old data.
