turn. One cycle time is therefore calculated as:

32 times × 1.5 msec. + 48 msec. = 96 msec.

This method is beneficial for giving a priority to contact signals which vary rapidly.

■ TRANSMISSION LINE CONFIGURATION

1. BASIC CONDITIONS

The multi-drop transmission line should fulfill the following conditions. Contact M-System's sales office or representatives

when designing.

A) 10 kilometers at maximum in total system.

B) Twisted-pair cable (code 1): a multi-drop section composed only of twisted-pair cable can have at maximum of

16 units within the total distance of 1 kilometer.

C) Fiber optics cable (code 2): a system can have at maximum of 6 multi-drop sections composed only of fiber optics.

Insert a pair of units of code "7" for waveform shaping between each 5 units of code "2".

1 kilometer max. between each unit.

D) Twisted-pair & fiber optics (code 7): a transmission line can have at maximum of 8 units of code "7". Units of code "1"

and "2" can be mixed in each section within the above limitation.
