Summary:

This article explains how to configure a Parani Bluetooth adapter to communicate with your meter, listing three prerequisites: a direct serial COM connection (typically via a USB-to-serial cable), the ParaniWin configuration software, and knowledge of the adapter’s baud rate (default 9600). It then gives step-by-step instructions—ensure all dip switches are OFF, connect and power the Parani, open ParaniWin and select the correct COM port/baud, set Device Settings (Operation Mode MODE3, meter-specific baud/parity/stop bits, Hardware Flow OFF, Command Response OFF), apply the changes, and verify the completed configuration before testing in the truck.

Question:

How to configure a Parani Bluetooth Adapter to work with my meter.

Environment:

Mobile Delivery
Parani Bluetooth Adapter

Answer:

You will need three things prior to being able to configure your Parani Bluetooth Adapters. Here are the prerequisites that you will need before you can configure your devices.

First, you need to be able to plug the Parani directly into a Windows computer via seral COM port connection. You will also need to know what COM port the connection is on. The easiest way to do this is to use a USB to Serial cable. Please read this article first if you do not already have a serial COM port connection.

Second, you will need the ParaniWin configuration software installed on your Windows device that you are using to configure the bluetooth adapters. Here is a link to the manufacture website where you can download and run the software installer: https://www.senanetworks.com/products/parani-sd1000-bluetooth-serial-adapter

When running the installer, you may receive a Windows Defender SmartScreen alert. In the event that you see that alert, simply click "More Info" and then select "Run Anyway". If you have any other issues downloading and/or installing the ParaniWin software then please reach out to the manufacture or your IT group for further assistance.
Third, you will need to know what baud rate the Parani Bluetooth Adapter is currently set to. They come default set to 9600 baud rate. If this is not a new device and you are unsure what the baud rate is set to then you can factory reset the Parani device back to default settings.

After you have the prerequisites you can follow these steps to configure your Parani Bluetooth Adapters.

First, please make sure that all 4 dip switches on the Parani are in the Off Position. This article covers how to configure a Parani using the ParaniWin software. This is considered a "Software Configuration" which means the dip switches are not used and should always be turned off. The dip switches are meant for "Hardware Configuration" which we currently do not support.

Note: All 4 dip switches on Parani's should always remain in the Off Position. If they are ever moved then the Parani will need to be reconfigured again following these steps.
Then connect your Parani to your USB to Serial cable. Then connect the power to the Parani and turn the switch on to power it up.
Open up the ParaniWin software by double clicking the icon.

Upon app startup you will be prompted to "Please setup serial port for configuring Parani-SD/ESD." Select these settings below and press OK. When selecting the baud rate to connect, choose 9600 if the adapter is new or has been reset to default. If 9600 does not work, and this adapter was previously configured for an LCR meter, try 19200.

Serial Port:	(select the com port that your usb to serial adapter is using)
BaudRate:	(select the baud rate your adapter is already configured for. 9600 if it is new/default)
Parity:	None
StopBit:	1

Example:

If the Parani device is preconfigured then you might get this message about the Command response option has been disabled and will be enabled to use the software. This is fine, you can press OK. This just means that we will need to make sure it is disabled when we configure the device.

Go to the Device Settings screen once you are connected. Select the correct settings listed below and when everything is correct press the Apply button to configure the device.

Operation Mode:	MODE3
Baud Rate:	(baud rate for your model meter. See chart below for what baud rate your meter uses.)
Parity:	None
StopBit:	1
Hardware Flow Control:	OFF
Command Response:	OFF
*Device Name:	*Optional - change if you would like

Meter Baud Rate Chart:

LCR-II	19200
LCR-600	19200
LCR-iQ	19200
Mid:Com e:Count	9600
Neptune E4000	9600
Mechanical Meter	9600

After you press apply the software should configure the device. You should receive a Completed configuration message. If you do then you can press OK and exit out of the software. Then you can turn off the Parani, unplug power, and remove the device.
