Mandatory
1.In configuring a system using 10BASE5,
make sure not to exceed the maximum
cable length of 500 m per segment and the
maximum number of MAUs(100)
2.In configuring a system using 10BASE5,
make sure that MAU intervals will not be
less than 2.5 m.
3.In configuring a system using 10BASE5,
make sure that AUI cable length will not
exceed 50 m.
4.Configuring a system using 10BASE5
requires MAU and AUI cables.(See 3.6
Network Component.) Purchase them as
necessary for your system.
Mandatory
1.In configuring a system using 10BASE2,
make sure not to exceed the maximum
cable length of 185 m per segment and the
maximum number of MAUs (30).
2.In configuring a system using 10BASE2,
make sure that node intervals will not be
less than 0.5 m.
3.Configuring a system using 10BASE2,
requires terminators and T-adaptors. (See
3.6 Network Components.) Purchase them
as necessary for your system.
Mandatory
1.Before applying voltages to the MAU power
terminal board, be sure to correctly connect
the 12-VDC cable with attention to the
positive and negative polarities.
Failure to observe this could cause trouble.
2.For module wiring, either use crimp
terminals with sheath or cover the wires with
tape so that there will be no exposed
conductors. Handle the terminal board cover
with care not to drop or break, and place it
securely on the terminal board after the
wiring. Exposed conductors could cause
electric shook.
3.It is recommended that external power be
switched on/off at the same time as T3H
power is switched on/off, if possible.
it is difficult to simultaneously switch
external power and T3H power on/off,
observe the following sequence.
Switching power on: T3H power first,
then external power
Switching power off: External power
first, then T3H power
Failure to observe the above sequence of
switching power on/off could cause trouble,
malfunction and/or shortcircuit.
Mandatory
1.ASK a qualified company for 10BASE5/
10BASE2 installation because it requires
adequate safety measure and conformity
with the standards. For the specifications of
environmental conditions for installation,
refer to JIS X5252.
Do not cover the hole of the equipment, and the
ventilator/air inlet of the system.
Otherwise, overheating, etc. can cause fire
or malfunction.
