9.4. Parameter Group 5 – Communication Parameters
9.4.1. Overview
The P2 Solar Pump drive provides many methods to allow the user to connect to a variety of fieldbus networks. In addition, connection
to options such as external keypads, PC and Optistick are possible. Parameter Group 5 provides the parameters required to
configure the various fieldbus interfaces and connection points.
9.4.2. Connecting Invertek Drives Options
All Invertek Drives options which require communication with the drive, such as the Optiport and Optipad remote keypads and
Optistick connect to the P2 Solar Pump drive using the built in RJ45 connection point. The pin connections on these options are
already matched, such that a simple pin to pin plug in cable can be used to connect these options without any special requirements.
For further information on connecting and using these optional items, refer to the specific option User guide.
9.4.3. Connecting to a PC
The P2 Solar Pump drive may be connected to a PC with Microsoft Windows operating system to allow use of the Optitools Studio
PC software for commissioning and monitoring. There are two possible methods of connection as follows:
Wired Connection. Requires the optional PC connection kit OPT-2-USB485-OBUS which provides a USB to RS485 serial port
conversion and premanufactured RJ45 connection.
Bluetooth Wireless Connection. Requires the optional Optistick OPT-2-STICK. The PC must have Bluetooth onboard or a suitable
Bluetooth dongle which can support a Bluetooth serial connection.
With either communication method, the steps to establish a connection between the PC and drive are as follows:
Download and install the Optitools Studio PC software to the PC.
Start the software, and select the Parameter Editor function.
If the drive address has been changed in parameter P5-01, ensure that in the Optitools Studio software the Network Scan Limit
setting in the lower left corner of the screen is set to the same or higher value.
In Optitools Studio select Tools > Communication Type
o If using the Optistick, Select BlueTooth
o If using the wired PC connection kit, select RS485.
In Optitools Studio select Tools > Select COM Port > Select the COM port associated with the connection.
Click the Scan Drive Network button in the lower left corner of the screen.
