4 / 10 page  SCD8638 Rev D 3/21/08 Aeroflex Plainview 4 MIL-STD-1553B Telemetry & Commands (Each 12-cell battery) Analog or bi-level telemetry can be requested from either the primary or the redundant controller and reported over the dual redundant 1553B interface with the RT addresses configurable at the J1 and J4 connectors. Analog Telemetry Each analog telemetry item can be requested individually on sub-addresses 18, 19 or 22. First a 1553B receive command with one data word as defined in Table I, which specifies the telemetry item being requested, must be issued. After a minimum delay of 1.2ms, the data can be retrieved by sending a 1553B transmit command for one data word on the same sub-address on which the request was initiated. The 12-bit data reply is left justified in the 16-bit 1553B data word with the four LSBs set to "0". Bi-Level Telemetry Bi-level telemetry can be requested on sub-addresses 18, 19 or 22. First a 1553B receive command with one data word as defined in Table II, which specifies the telemetry item being requested, must be issued. After a minimum delay of 1.2ms, the data can be retrieved by sending a 1553B transmit command for one data word on the same sub-address on which the request was initiated.
