1.2.1.3 Option C – RS-422/-485 Serial Input Port Options
The base configuration of the Centurion II has no RS-422-485 serial input ports.
At the time of the original purchase, you can specify the number of RS-422/-485
serial input ports.
The RS-422/-485 Serial Input Ports circuitry is surface mounted onto the Main
Module printed circuit board. It is not advisable to attempt to add these
components at a later date and any such field revision will void all remaining
warranty on the RTU. If at a later date you wish to add RS-422/-485 Serial Input
Ports circuitry, we recommend that the Main Module of the RTU be returned to
the factory for modification and re-verification. Your local sales representative
will quote the cost of this modification at that time.

1.2.2 Discrete Input and Relay Output Options
Centurion II has been developed to offer maximum flexibility when purchasing or
expanding the device. Because all discrete inputs and control relay outputs are
mounted separately from the CPU module, expansion is simple.
The standard I/O module contains 64 discrete inputs and 8 control relay outputs.
A partially loaded module with only 32 discrete inputs and 4 control relay outputs
is also offered. This partially loaded module can be replaced at some later date
with a fully populated board. Because of the complexity of the circuitry it is not
advisable to attempt to add these components at a later date and any such field
revision will void all remaining warranty on the RTU.
The RTU chassis can accommodate up to 128 discrete inputs and 16 control relay
outputs. Additional expansion chassis can be added immediately above or below
