2.1
Activation of the PC-ATC Connection
To operate the remote control program, it is essential the PC and ATC can communicate by
serial interface.
The connection can be realized in different ways, since the ATC is provided with two
independent serial interfaces:
2.1.1
RS 232 Direct Connection
•
Connect the ATC and the PC using the connection cable.
•
Can be used to quickly connect the device during commissioning / maintenance.
•
It is possible to connect only one device at a time.
2.1.2
RS 485 Connection
•
Connect the ATC through a COM-Interface (e.g. RS 232 / RS 485 converter) to the PC.
•
Connect all ATC RS 485 interface terminals in parallel with the twisted-pair cable and then
to the interface converter, as shown in the following wiring diagram. Make sure the polarity
of RS 232 / RS 485 is correct (A and B terminals).
•
The interface converter must be insulated and have an automatic enable line control
circuit.
•
In case you have connected more than one device, from the front keyboard of each device,
enter the Function setup and set one different RS 485 serial address for each ATC, starting
from address 01. Make sure that the PC speed and parity settings match the ATC RS 485
setting.
