Linking Multiple Supplies; Communication Daisy-Chain; Series And Parallel Supplies - TDK-Lambda GENESYS User Manual

8. Linking Multiple Supplies

Using one Genesys™ with USB, you can control more than one Genesys™ power supply. The connection
between the supplies can be just to share a communication port, and/or you can connect the outputs for series
or parallel supplies.

8.1. Communication Daisy-Chain

One Genesys™ with USB can be used to control a whole chain of supplies by using the J3-IN and
J3-OUT connectors with RS-485 linking cables.
Each power supply must be set with a different serial address. Communication to each supply is done by
sending the addressing command "ADR nn" to select a power supply at address "nn".
To Set the Serial Address:
For the USB Master: view the serial setting as shown in section 7.6. Rotate the voltage encoder to
set any address 0 to 30. Wait a few seconds for the address display to clear and update the new
setting.
For the Slaves: view the serial setting similar to section 7.6. Rotate the voltage encoder to set any
address 0 to 30. ALSO verify the current display is set to "19.2" for 19200 Baud. Rotate the current
encoder to change it. Wait a few seconds for the display to clear and update the new setting.
Refer to the Genesys™ User Manual for more information on the link cable, selecting RS-485 and
setting the address and Baud rate.

8.2. Series and Parallel Supplies

You may connect the outputs of Genesys™ power supplies together to produce:
Voltages greater than any one supply rating (series connection).
Plus and minus polarity (series connection).
More current than any one supply rating (parallel connection).
With any of these output configurations, you can have USB communication to all the supplies by using a
communication daisy-chain as described above.
With any of these output configurations, you can use the features of an analog control chain, a shut-off
daisy-chain or Advanced Parallel.
Refer to the Genesys™ User Manual for more information on series and parallel supplies and their
features and warnings.
