Activation of the PC-ATL connection
To operate the remote control program, it is essential the PC and ATL can communicate by serial interface.
The connection can be realized in different ways, since the ATL is provided with two independent serial
interfaces:
RS-232 direct connection
•
Connect the ATL and the PC using the Lovato cable code 51C2
•
Can be used to quickly connect the device during commissioning / maintenance
•
It is possible to connect only one device at a time
RS-485 connection
•
Connect the Rs-232/Rs-485 converter to the PC using cable 51C4.
•
Connect all ATL 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 is correct ( A and B
terminals).
•
We strongly recommend to use an interface converter supplied by Lovato. If the user wants to use an
interface converter of another brand, we will not able to help with wiring, nor to assure that the
communication will work properly. However, 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 ATL, starting from address 01. Make
sure that the PC speed an parity settings match the ATL RS-485 setting.

Modem connection
Using the remote control it is also possible to achieve connection from a remote location, using a couple of
modems. Modems can be of standard type or GSM, and can be connected on the RS-232 or RS-485 port.
See the I106IGB1002 document on the original CD for more details about modem connection.
When working with modems, both the PC software and the ATL must be set to work with modbus® ASCII
protocol. See the Configuration-options chapter and the Function setup parameters on the operating manual
of the ATL.
