BMC 1553 REPEATER is an intelligent device with a fast and low power RISC processor capable of reconstructing and boosting bi-directional signals on 1553 coaxial cables. The repeater is available as either single or dual 1553 channel.  Alternately, the unit can be configured as a splitter. Note that the information coming from a single input can be retransmitted to up to three different output cables. These configurations are maintained inside the processor and are field programmable. The Repeater board includes RF protections

The BMC repeater board is an efficient solution for long connections between devices. The unit automatically recognizes incoming information and retransmits without any delay. The repeater has up to two dual redundant channels for full support to MIL-STD-1553 requirements.


BMC 1553 \ 1760 Splitter

Using this format, the repeater transmits to a common “input” and data is retransmitted through up to three “outputs”.  The system constantly tracks signals coming from the three connectors.  If the two “outputs” transmit data the first output cached by the intelligent processor is going to be retransmitted to the common “input”. 


The BMC Repeater/Splitter is available with the following options:

1-     Single or Dual repeater- single channel or dual (A & B).

2-    Bus resistor terminator.

3-    Repeaters with or without a box.

4-    Repeaters with or without a power supply.

5-    Embedded Bus Analyzer through standard RS232 serial port.

6-    Customize PCB shape to meet customer requirements.

7-    Customize box to meet customer requirements
