OVERVIEW OF CONTROL TECHNOLOGIES
IR
Basic infrared control used for most remote controls. There is no limit to the length of cable.
Uses two wires of a shielded cable e.g. minijack cable. Fluorescent lights can interfere with IR.
Note motorised projection screens with remotes are normally RF – not IR. This product cannot
learn RF codes.
This product
Learns and replicates codes sent from a device's infrared remote control
•
Can use Philips Pronto codes to control equipment.

12v Trigger
Used to trigger relays. State is OFF or ON. Often used to activate motorised projection screens.
Uses 2-core unshielded cable e.g. speaker cable
Ethernet RJ45
Many projectors and displays have a network connector for control now. Generally this uses the
same codes as RS-232, but the signal is carried over a network to make it easier to distribute.
RS-232
Advanced control format. More reliable than IR because it is wired and uses two-way
communication.
When a command is sent the device can respond that it has taken action. Note this product is
intentionally simple and ignores those responses.
