SPI Extender
DDS1120 is a Syncronous Peripheral Interface (SPI) signal amplifier. This amplifier allows you to extend the Balanced or Unbalanced SPI signal up to a maximum of 100/150 meters, ensuring the quality of the transmitted signal. It can be connected to the Trex Pro or Trexbis or DDS11062, if the signal to be amplified is of type Balanced so we have A and B for SPI Clock and SPI Data, then only one DDS1120 device is needed, in case the signal is not then two devices are used one in transmission mode and one in receiving mode, the switch on the side depending on the position makes the transmitter and receiver in the same module, the state if TX or RX is clearly indicated by the LEDs on the box. Wiring between two extender modules is done with cat 6 Ethernet cable , RJ45-8 Patch connector, do not use Cross cables. The special connectors with cable lock springs allow connection with the SPI lamp or the SPI Master transmitter. Be careful not to connect Ethernet on the RJ45-8 connector is not compatible and may damage your
