1. Ethernet
2. USB
When the INGECON SUN ComBox acts as a communication gateway, the input points 1, 2 and 3 are directly
connected to the sole output point available.
In the event that the device requires the power setpoint order to be sent (or other information), to
prevent collisions in the RD-485 output the input points 1, 2 and 3 are momentarily disconnected
for the duration of the transmission.
In order to change the power setpoint, see the section "7. Connecting digital inputs: power setpoint".
