BU-63705 complete dual redundant Remote Terminal Unit (RTU). fully compliant with MIL-STD-1553B supports message formats. shown FIGURE includes transceivers custom chip containing encoders decoders, processors, protocol sequencer control logic, output latches, buffers. With addition data transformers, BU-63705 ready connection MIL-STD-1553 data bus. Data transferred from subsystem host over 16bit parallel highway, which isolated bi-directional buffers. transfers made with type handshake sequence request, grant acknowledge. Read/write data strobes provided simplify interfacing external RAM. Also simplifying interface availability latched command word auto-incrementing word counter. These signals used address data directly from RAM. Data Device Corporation www.ddc-web.com

STATUS REGISTER
inputs BU-63705 allow subsystem host control bits status word. Illegal Command input used Message Error Status Word suppress transmission data controller. This line allows illegalization combination commands. latched Command Word connected address pins optional external PROM, which would drive illegal Command line when identifies command programmed illegal.
BUILT-IN-TEST
BU-63705 contains 14-bit Built-In-Test (BIT) word register which stores information about condition RTU. When mode code received transmit word, contents register transmitted over 1553 bus. FIGURE shows fault assigned each word. Conditions monitored are; transmitter timeouts, loop test failures, transmitter shutdown, subsystem handshake failure, results individual message validations.

TRANSFORMER CONSIDERATIONS BU-63705X3 (+5V ONLY VERSIONS)
selecting isolation transformers used BU-63705 (+5V only) versions, there limitation maximum amount leakage inductance. this limit exceeded, transmitter rise fall times increase, possibly causing amplitude fall below minimum level required MILSTD-1553. addition, excessive leakage imbalance result transformer dynamic offset that exceeds 1553 specifications. maximum allowable leakage inductance measured follows: side transformer that connects Hybrid defined "primary" winding. side primary shorted primary center-tap, inductance should measured
across "secondary" (stub side) winding. This inductance must less than Similarly, other side primary shorted primary center-tap, inductance measured across "secondary" (stub side) winding must also less than difference between these measurements "differential" leakage inductance. This value must less than Beta Transformer Technology Corporation (BTTC), subsidiary DDC, manufactures transformers variety mechanical configurations with required turns ratios 1:2.5 direct coupled, 1:1.79 transformer coupled. Table provides listing many these transformers. further information, contact BTTC 631-244-7393 www.bttc-beta.com.
