Once the address conguration and physical connection is complete, test set operation is the
same as for serial operation.
14.2. RTU Mode
In RTU Mode, the test set will operate as a remote device and respond to commands received
from a SCADA Master. Special conguration is not necessary for network communication. As
the “remote” device, the test set software will accept incoming connection requests and, from
that point on, test set operation is the same as with a serial connection. If the device protocol
address is set to the default value *, the test set will respond to requests containing any address.
Alternatively, a specic protocol address (RTU address) for the device is can be specied the
same as with the serial version of the protocol on the Exchange List view by double-clicking on
the exchange name or setting the address on all exchanges using the “Properties > Protocol
Specic>ExchangeDefaultstab”.
In RTU Mode, there are no special connection requirements or connection restrictions. The test
set PC can be connected directly to the remote device, through a router, a switch, or a hub as
shown below.

14.3. Monitor Mode
In Monitor Mode, the test set will monitor and display communication messages between two or
more devices that are communicating using the designated network protocol.
Unlike Master Mode and RTU Mode, there are physical connection requirements that must be
followed in order for the test set to have access to the messages between the devices to be
monitored.
