Connecting Steps

Mounting

To mount the transmitter Lightware supplies optional accessories for different usage. There 

are two kinds of mounting kits with similar fixing method. The transmitter has two mounting 

holes with inner thread on the bottom side. Fasten the device by the screws enclosed to the 

accessory.

The Under-desk double mounting kit makes it easy to mount a single device on any flat 

surface, e.g. furniture. 1U high rack shelf provides mounting holes for fastening two half-rack 

or four quarter-rack sized units. Pocket-sized devices can also be fastened on the shelf. To 

order mounting accessories please contact 

[email protected]

.

 The transmitter is half-rack sized.
