iHP Manual 11 | P a g e
The simplest way to get started is to use the Power Pro Connect Module (PPCM) to establish a link to the
supply. The PPCM allows the user to quickly establish a connection with the power supply with a Web based
GUI and set up the power supply. The configuration of the supply can be set up to run autonomously when
powered on, controlled via rear panel digital and analog input and outputs, or actively controlled via the
PPCM.
For more advanced users developing their own software control, the PPCM is not required and the supply can
be directly interfaced via the users preferred standard communications protocols, including CANbus, Ethernet
and RS485.
