at 200kHz

For line lengths in excess of 1220 metres the line should

be split into smaller sections with intermediate repeaters.

APPLICATIONS

Figures 15 shows a typical application of the device on a

half--duplex network. The line should be terminated at

both ends to minimize reflections and any stubs off the

main line should be kept as short as possible.
