PSI 9000 2U Series

How to connect the master-slave bus:

1. 

Switch off all units that are to be connected and connect them together with network cables (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. 

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.

►

Position: not terminated 

(standard)

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 

acknowledged with OK, otherwise the change will be reverted.

3. 

Accept the settings with the touch area 

 and return to the main page. 

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 

 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 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:

Tapping INITIALIZE can be used to repeat the search again, in case the de-

tected number of slaves is less than expected. This can be necessary if not 

all units are set as SLAVE or the cabling/termination is still not OK. The result 

window shows the number of slaves and the total current and power of the 

MS system.
In case there are no slaves found or not present, i.e. not powered, the master 

will still initialise the MS system with only itself.

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.
