Serial Housekeeping Channel

CUBIC transmits 24 multiplexed 8 bit words to the Telemetry Processor on one serial HK channel. One of these words is an 8 bit command status word (BL2). This word is used to monitor the status of commandable CUBIC operation modes. The bit assignments for BL2 are given in Table 17. The bits labeled ``Relay Status'' use the second pole of our DPDT latching relays to produce a logic level indicator of the status of the relay contacts. The other 23 words are the 8 most significant bits of 23 of our analog housekeeping signals (see Table 17 for the TM matrix assignments; see Table 12 and Table 15 for the housekeeping assignments).
