The external connector (J1) is used to communicate with the SDU and for the power
supplies of the FMHPA.

Internal connectors are used to:

•

Connect the PSM and the CM

•

Connect the RF SRU to the Logic SRU for power supplies and the
communication signal.

•

Supply a test connector for testing and downloading.

B. Software
