2.6 Notes on Q4ARCPU Duplex System

2 - 9
This section describes the notes on the connecting of the Q4ARCPU with the GOT, as
follows:
(1) Notes on the additional base for duplex system at the final stage:
To connect the duplex system with the GOT via the bus, connect the GOT with the
additional base for duplex system (A68RB) that is provided at the final stage of the
duplex system. To use the additional base for duplex system, please apply that of
the Version B or after.
• In the following configurations the GOT will not operate normally as specified.
(a) The configuration in which the GOT is connected with the fundamental base
for the duplex system (A32RB, A33RB) is connected via the bus.
(b) The configuration in which the GOT is connected with the additional base
(A68RB) for duplex system of Version A is connected via the bus.
• To check and confirm the version of the additional base for duplex system, please
refer to the DATE column on the rating plate that is adhered to the part as shown
in the illustration below.
(2) Notes on 5V DC supply for the additional base (A68RB) for duplex system at the
final stage:
220mA of current to be consumed will be supplied from the additional base for
duplex system at the final stage to the GOT bus interface, if the GOT power supply
is off and the power supply for the power supply module mounted on the additional
base for duplex system at the final stage is on. Therefore, please make sure that
the 5V DC consumption (8A) of the power supply module will not be exceeded by
the sum of the value of the current consumption of the input/output module and
special function module that are mounted on the additional base for duplex system
at the final stage and the value of the current consumption (220mA) of the GOT
bus interface.
