Page 3: General Information
1.1. WARRANTED INFORMATION ADA-7240 converter is covered by a two year warranty from date of sale. In case of being damaged it will be repair or the damaged component will be replace. The warranty does not cover damage caused from improper use, materials consumption or any unauthorized changes. -
Page 4: Description
The use of fibre-optic provides complete isolation between connected devices and resistance to interference on the transmission bus. Fiber optic connection is made by the use of two fibres. ADA-7240 can be use also for extend the fiber optic bus for next part 2500m because the converter also complies functions of fiber optic repeater. -
