► How to connect the master-slave bus
1. Switch off all units that are to be connected and connect them together with a network cable (CAT3 or bet-
ter, not included). It doesn’t matter which of the two master-slave connection sockets (RJ45, backside) is
connected to the next unit.
2. Also connect all units 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.

Position: not terminated (default)
Position: terminated
Now the master-slave system must be configured on each 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 until reaching PAGE 9.
2. Activate the MS mode with touch area . A warning requester will appear which has to be ac-
knowledgedwithOK,otherwisethechangewillbereverted.
3. Accept the settings with the touch area and return to the main page.

► Step 2: Configuring the master unit
1. Enter then GENERAL SETTINGS and press until reaching PAGE 9.
2. Specify the unit as master with tough area . A warning requester will appear which has to be
acknowledgedwithOK,otherwisethechangewillbereverted.
3. Accept the settings with the touch area and return to the main page.
► Step 3: Initialising the master
The master unit and the whole master-slave system still need to be initialised. In the main screen of the master
unit, after quitting the setting menus, a pop-up will appear:
Tapping INITIALIZE will cause the unit to search again for slaves and then to
congureitselfforsetandactualvaluesaccordingly.Ifmorethanonecorrectly
congured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.
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: 10.
