Note
1.
Previous Master Unit models (without -V1), which do not support the Long-
distance Communications Mode, cannot be used when an Analog I/O Ter-
minal is connected as a Slave. If used, incorrect data may be transmitted.

Refer to
SECTION 4 Master Unit Specifications and Operations
for more
details on the Master Units.
Master with Built-in CPU
The following Master Control Unit models, which have a built-in CPU Unit, are
