This update brings additional options for digital inputs and outputs to the Central Box 200. Now you can simply control your LED lights using the Central Box only. The Central Box can function as an EX Bus expander so you can join several Central Boxes together and you’ll have perfect signal distribution and control redundancy in a model.

The 1.20 firmware version for the Central Box 200 adds a digital interface function to the existing settings for the output pins. Individual Central Box 200 outputs can now be configured as one of the three modes; classical servo output, digital output or digital input. In the digital output mode, only the logical level 1 or 0 is generated on the port configured this way. The value of this output is reflecting the assigned output channel and its level. If the servo position of the specified receiver channel is lower than 0%, i.e. 1.5ms (the decision limit point can be set by the user using the „Trigger“ parameter), the output is set to permanent log. 0 (i.e. 0V). If the servo position is higher than 0%, log. 1 (i.e. 3.3V) will be generated on the pin. In the digital output mode, no control servo pulses are generated for that particular pin.
The Central Box with the new firmware can also function as an EX Bus Expander. This function can be activated on the Ext1, Ext2 and Ext3 outputs and this will function even if the Central Box is controlled by the PPM signal (Rx1 and Rx2 input). The Central Box transforms the servo positions from the PPM signal to the EX Bus. The Central Box can detect any sensor that can communicate in EX Bus mode and starts the communication with the sensor automatically using EX Bus protocol.
