4.9 J7 PPM ISP Connector
This connector provides the I/O interface between the
PPM and the PIM. The following groups of signals are
provided:
General purpose outputs
The SPI bus (MOSI, MISO, SCK)
Connections for three PPM “Status” LED’s
Target power supply +5V and a special negative
voltage output signal
General purpose Inputs (reserved for future use)
