3.11.1.6 Conguring the master-slave operation
Now the master-slave system has to be congured on each unit. Its recommended to congure all the slave units rst and
then the master unit.
Step 1: Configuring all slave units
1. While the DC output is switched off, tap on in the main screen to access the Settings menu. Swipe up to nd
group Master-slave and tap it.
2. Tapping on the blue button text next to Mode will open a selector. By selecting Slave, if not already set, the master-slave
mode is activated and the device is dened as slave. Additionally, the bus termination can be activated here, if required
for the currently congured unit.
3. Leave the Settings menu.
After this, the slave is fully congured for master-slave. Repeat the procedure for all other slave units.
Step 2: Configuring the master unit
1. While the DC output is switched off, tap on in the main screen to access the Settings menu. Swipe up to nd
group Master-slave and tap it.
2. Tapping on the blue button text next to Mode will open a selector. By selecting Master, if not already set, the master-slave
mode is activated and the device is dened as master which also automatically enable the BIAS resistor termination,
as required for the master.
Step 3: Initializing the master
When setting a device to Master, it will instantly start to initialize the MS system and the result is displayed in the very same
window. In case the initialization is not successful or the number of units or the total power is wrong, it can be repeated in
this screen anytime.
Tapping Initialize system repeats the search for slaves in case the
detected number of slaves is less than expected, the system has been
recongured, not all slave units are already set as Slave or the cabling/
termination is still not OK. The result window shows the number of
slaves plus the total current, power and resistance of the MS system.
In case there are no slaves found at all, the master will still initialize the
MS system with only itself.
As long as MS mode remains activated, the initialization process of the master-slave system will be re-
peated each time the master unit is powered. The initialization can also be repeated manually anytime via
the Settings menu, in group “Master-Slave”.
