CDX800 DESCRIPTION
make up simple technology control, where changes on input signals of one module can control
remote outputs of the other module and vice versa.
Interface between I/O connector and technology is supplied for general use, 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 use of industrial control
automatic. Inputs and outputs for telemetry.

PORT1 interface
PORT1 interface in the CDX 800 modem is software configurable between serial link
RS232 and RS485 bus. Configuration is possible by the program RADWIN
[3]
. If it is selected
RS485 bus, the CDX 800 modem can automatically detects service cable. After time
of modem configuration the PORT1 interface is temporary switched to RS232 serial link.
2.4.5.
Optional hardware interface PORT2
PORT2 on the CDX 800 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
CDX 800. Thus you may use the CDX 800 module combined with RS232, RS485/RS422,
M-BUS or CNT. Such interface is physically linked to RJ45 PORT2 connector.
2.4.6.
User interface protocols
There are numerous standard industrial protocols implemented on the user interface:
ARNEP UI
AT modem
DLMS MODBUS
IWKA
M-BUS
MODBUS
PROFIBUS
RADOM
RDS CONEL
SAUTER
SBUS
Transparent bus
New protocols can be implemented according to the customer's needs not supported
by the communication module yet. The CDX 800 module also enables the implementation
of customized user protocol directly by the customer.
In case of M-BUS expansion board installed and when chosen protocol is not M-BUS
or M-BUS TCP then sent data will be returned back to the device! If e.g. LINE protocol is set-
up on this port, then data will return back to the source.
