The IR communication option allows FRED to be triggered from a signal generated electronically.
One IR module is mounted on FRED and the other is mounted such that it is within 1m and has a line of sight view of the module mounted to FRED.
IR communication is ideal for automating assembly lines. This option allows FRED to interface with a computer or PLC. Through this interface, FRED can be commanded to move to the next location without the need for a person to press a go button.
