Networking
Many ChromoFlex modules can be operated within a network. This means each module can either
send or receive data! Connectors for RS232-RX and RS232-GND are required.
It is a precondition for network operation that all modules of the network have a common GND with
the power supplies.
If a button is pressed on any module, it will pass this command to all other modules connected over
the network as factory default.
Note: the data transmission protocol is based on a mathematical algorithm that is very robust against
transmission errors.
Important: For correct operation it is required to add a resistor of around 10 kOhms (Low Cost) to the
bus. This resistor is included in the PC adapter kit delivered from stock. A shielded low frequency
cable is very well suited for network lines. For short networks (< 5 metres) an unshielded cable is also
suitable. The 10 kOhms resistor should be connected between RS232-RX and RS232-GND
somewhere in the network, from where the signals are sent to the PC. The connection from module to
module requires only RS232-RX and the common GND.
