Cable Lengths

The permissible cable lengths for use with the LOGIC bus depend on
the number of indicators and of the quality of cable in question.
A standard installation with two steering positions usually comprises 12
indicators. The indicators at a steering position are linked with the cable
supplied with the indicatos if their arrangement permits doing so.
Up to a length of 8 meters (26 feet), unshielded cable may be used to
bridge the distance between two steering positons.
If a longer connecting cable is required, or if more than 12 indicators are
to be connected, shielded cable will have to be used for each of the
leads of the LOGIC Bus. In either case cable meeting the RG 58 stan-
dard will be a must. The shielding of the two cables will have to be
connected at the main instrument side to terminal 9 of the indicator.
If shielded cable is used for connection to the LOGIC bus, the cable run
between the two steering postions must no exceed a maximum length of
16 meters (52 feet).
The total number of indicators connected to the LOGIC
bus must not exceed 15 in that case.
