8.2 Setting up the Remote Reference Unit
If a Remote Reference Unit is to be used, then this section details how the HAYSYS PIU Utility is
used to perform the data ‘bridge’ between the IP Address and the USB port on the RRU.
NOTE:
The PIU Utility must be running on the Host PC at all times when the PIU units are being
used in the field.
As with the PIU configuration procedure, connect the RRU to the host PC via the supplied USB
cable. Start the PIU utility application on the host PC and press the ‘Scan for device’ button. The
utility will automatically identify the connected RRU as a reference unit as shown in Figure 12
below.

Next, set the server address by selecting the ‘Server’ tab and entering the IP address of the host
PC. The IP address can be ‘discovered’ by clicking on the ‘Discover’ button. This will
automatically enter the IP address of the host PC or present a ‘drop-down’ list, if multiple IP
Addresses are discovered. Next enter the port number to be used, as shown in Figure 13 below.
