 Infra-Red transmission signals are 'line of sight' and as a result are inherently 'range controlled'. This means that operation is inherently safe with the operator being able to move freely throughout the determined operational footprint. Operating performance of systems using Infra-Red as the transmission medium is easily determined and optimised by the number of receiving sensors strategically installed beneath the structure and in sight of the ground based operator. Too many receiving sensors will exceed the requirements and too few will affect the operating performance.
COMMANDER Infra-Red systems incorporate Automatic Gain Control (AGC) so wherever the operator is positioned within the operational corridor, consistent system performance is assured. Depending on the installed height of the applied to equipment, fine tuning of the range can be achieved during installation (or later) by the use of the systems in-built manual gain control setting facility. Infra-Red signals are not affected by electrical or electronic pollution although high levels of white light can cause interruption to the transmitted signal by blinding the receiving sensors.
 As with radio based systems, COMMANDER Infra-Red systems incorporate installer settable address coding switches on the transmitter. When set the installer 'teaches' the selected code to the 'on-crane' receiver system.
COMMANDER Infra-Red based systems provide the same high level of flexibility as radio based systems when additional optional features are required. |
