CGU 04i DESCRIPTION
7
The microprocessor further manages numerous functions of servicing, diagnostic and
installation purposes. Data transfer statistics, separate port communications, power blackouts,
voltage of the reserve supply, CGU 04i temperature and other important information –
everything is recorded in the microprocessor’s memory.
CGU 04i settings are saved in FLASH EEPROM memory. Service SW RADWIN is
designed for CGU 04i module configuration. The description of programme RADWIN is
in reference

2.4.3 Telemetric inputs and outputs
Apart from serial data interfaces there is CIO interface established in the module.
These are 5 signals to be used as analogue or binary inputs or binary outputs with an open
collector. The input is analogue 0 – 5 V. It may be as digital with control level adjustment.
The output is an open collector able to switch up to 500 mA. Reading and control of I/O signals
is possible from the remote CGU 04i module or any serial user interface. Simple technological
interface can be created by configuration of two CGU 04i modules, where you may control
remote outputs on the other module’s connector based on the input signals of one module.
Interface between CIO connector and technology is supplied for general use and it is
possible supplied this, providing voltage and current inputs of adjustable ranges, inputs for
resistance measuring (thermometers and the like), optically separated binary inputs and relay
outputs. With the equipment you may establish simple telemetry at low cost, without the using
of industrial control automates.
2.4.4 Optional hardware interface PORT2
PORT2 on the CGU 04i back panel provides for direct use of other HW interface than
the standard RS232. It is due to the design of the interface as a separate module built inside
CGU 04i. Thus you may use CGU 04i module combined with RS422, RS485, M-BUSD or
CNT. Such interface is physically linked to RJ45 PORT2 connector.
