Load input with positive voltage connected to pins 2 and 7 and ground connected to pins 4 and 8 There is fast 6 3A fuse installed in serial with Load input to protect the load against overcurrent in case of failure CCPSL acts as a regulated current load The current value is set by a controlling computer through RS232 serial interface The interface is optoisolated and requires small amount of power from the computer The supply voltage is taken from RTS line which must be active for the interface to operate correctly 12V It is therefore necessary to set flow control for the designated serial port to RTS CTS Transmission parameters are set to 2400 bauds 8 data bits no parity control and one stop bit 2400 8 N 1 All the internal CCPSL electronics is supplied from Load input Therefore there is always certain minimal current taken from the PS under test This current is equal to 30 mA To set a given current value the user has to send two bytes to CCPSL X current value 0x21 ASCII code of The maximum current value tha can be set is adjusted to 4 250 mA If we add 4 250 mA and a constant supplying current of 30 mA we will have the maximum current that can be set equal to 4 280 mA which gives a maximum power of 119 84 W for voltage of 28V A single bit weight is equal to 16 60 mA 0 465 W The minimum current of 30 mA gives a minimum load of 0 84 W 1 4 2 Example To set power to 45 W user has to send 45 W

15. 03 11 26 Issue 1 0 P Page 4 36 0 Introduction The purpose of the DRCU simulator is to replace the DRCU FPU during tests when the DRCU FPU are not available In particular this is the case for the Herschel Oavionics tests where it is part of the SPIRE Avionics Model AVM but it is also intended for DPU I F tests and the OBS development The communication between the DPU and the DRCU as defined in RD1 does not conform to any standard and for this reason a communication I F board called Hermes have been developed to mate to the PCI bus The driver software runs under MS WinNT and MS Win2000 As the DRCU will react promptly to commands by returning an echo including 2 bits acknowledgement the DRCU simulator must do the same This type of real time performance requires a kernel separate form the operating system and for this reason the Hermes software driver includes this feature The simulation software called application software feeds continuously the driver memory area with HK data status information simulated signal data etc In this manner there is always a fresh response available in the driver memory area for a request from the DPU The 32 bit command word has a 12 bit wide CID command identifier field and MSB 1 the command is a read called get command asking for a specific HK value or status parameter The simulator responds by first sending an echo identical to the command except with a 2 bit
