The Payload Interface Unit (PIU) provides the interface between payload equipment (GOCI, MODCS and Ka Band P/L) and the SCU. The PIU is a MIL-STD-1553-Bus Remote Terminal (RT). The MPIU distributes commands to, acquires telemetry from and takes part in the thermal control of the payload equipment. When in ON mode, the PIU is completely observable and can be used for payload control. When in OFF mode, the PIU is non active except the thermal control electronics.
