IR Output
This mode of versatile port provides output for infra-red emitters (IR Adapters). Parameters of IR output are as follows:
• The maximum IR carrier frequency is 500 kHz.
• Up to three original infra-red emitters (IR Adapters) can be connected to each output in parallel. All emitters send the same
IR codes. This configuration can be used for different types of devices.
WARNING: We do not recommend connecting more infra-red emitters from various manufacturers in parallel
because the output can be either overloaded or damaged.
