BMC MULTIPLE CHANNEL RUGGEDIZED SPLITTER- REPEATER is an intelligent device  capable of reconstructing and boosting bi-directional signals on MIL-STD-1553 and/or ARINC 708 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 dual-redundante 1553 and four ARINC 708  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.  


BMC 1553 \ 1760 Splitter

Using this format, the repeater transmits to a common “input” and data is retransmitted through up to four “outputs”.  The system constantly tracks signals coming from the  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-    28 VDC Power Input

2-    Bus resistor terminator.

3-    Repeaters with or without a box.

4 -    Customize PCB shape to meet customer requirements.

5-    Customize box to meet customer requirements
