► How to connect the digital master-slave bus
1.
Switch off all units that are to be connected and connect them with network cables (CAT3 or better, cables
not included). It doesn't matter which of the two master-slave connection sockets (RJ45, backside) is con-
nected to the next unit.
2.
Depending on the desired configuration the units can then be connected at the DC side.
3.
The two units at the beginning and end of the chain should be terminated, if long connection cables are
used. This is achieved using a 3-pole DIP switch which is positioned on the back side of the unit next to the
MS connectors.
Now the master-slave system has to be configured on each other unit. It is recommended to configure first all the
slave units and then the master unit.
► Step 1: Configuring all slave units
1.
Enter then GENERAL SETTINGS and press
2.
Activate the MS mode with touch area
knowledged with OK, otherwise the change will be reverted.
3.
Set the address of the slave between 1 and 15 with the left-hand rotary knob. Ensure that no address is
allocated twice.
4.
Accept the settings with the touch area
The slave is then configured for master-slave. Repeat the procedure for all other slave units.
► Step 2: Configuring the master unit
1.
Enter then GENERAL SETTINGS and press
2.
Specify the unit as master with tough area
acknowledged with OK, otherwise the change will be reverted.
3.
Accept the settings with the touch area
► Step 3: Initialising the master
The master unit and the whole master-slave system must now be initialised, which is done automatically after the
master unit has been activated for MS. In the main page, after quitting the setting menus, a pop-up will appear:
The initialising process of the master and the master-slave system will, as long as MS mode is
still activated, be repeated each time the units are powered. The initialisation can be repeated
anytime via the MENU in GENERAL SETTINGS, PAGE: 9.

Tapping INITIALIZE will cause the unit to search again for slaves and then to
configure itself for set and actual values accordingly. If more than one correctly
configured unit is found then this screen will show the number of slaves and
the combined total current and total power.
If no slaves are found, or the correct number is not displayed, then the settings
of all the slaves and the master together with the cabling must be checked
and setup process repeated.
