1. Introduction

1.1 Introduction

RADIUS Log Light is a newly research & design inverter monitoring product of Gefran. It can collect and
analyse photovoltaic station inverter running data via Bluetooth connection, and display monitoring data on
LCD screen, user can browse data on computer as well. RADIUS Log Light can monitor maximum 4 inverters
simultaneously.

RADIUS Log Light has standard data communication interface, including RS232 serial port, USB port, and
Bluetooth, it can smoothly compatible with your existing systems.

RADIUS Log Light has the following features:

1. Remote monitor and control

2. Communicate with APV inverters via Bluetooth

3. Monitoring data store in SD card which plug to RADIUS Log Light.

Fig 2.1 Simple chart of RADIUS Log Light

The following table is components explanation:

Number Name Explanation

1 RS232 For rmware update

2 SD CARD SD card socket

3 MINI USB Power supply or battery charge by MINI USB (cable includ-

ed as standard)

4 SWITCH Power on/off switch

Radius Log Light 7

2.2 Wireconnection

1) Insert the USB terminal of USB wire to power adapter socket, and insert the opposite terminal (MINI
USB) to MINI USB port socket.

2) Insert SD card to SD card socket.

3) Connect power adapter to public gird power outlet

4) Turn on power switch of RADIUS Log Light.

2.3 LEDindicator

There are 3 LED indicators on the right of LCD screen, you can get RADIUS Log Light running status by check­ing up the 3 LED lights.

LEDlights Function

BT Power Indicate Bluetooth modules status

BT State Indicate Bluetooth connection status

Charge Indicate charge status

1) BTPowerIndicator

If LED indicator blink once per several seconds, it shows bluetooth modules are working in normal sta-

tus. You can check out master device and slave devices by examine the blink interval of LED. LED blink
once every 2 seconds shown it’s a slave device, the master device’s blink interval is 5 seconds.

RADIUS Log Light is working in master mode and inverter bluetooth module in slave mode.

2) BTStateIndicator

Dark LED light indicates connection was established with other bluetooth device, a blink LED indicates

connection haven’t established.

If connection haven’t established, you can check whether RADIUS Log Light had stored logical address

of pair bluetooth device, by examine the LED blink times. Quick blink (2 times per second) indicate logi­cal address had been stored, slow blink (once per second) indicate haven’t stored the logical address.

For master device, blink once every 2 seconds when searching device, quick blink 4 times in a second

when nding a pair device, blink once when connecting, and become dark in connected status.

The two indicators (BT power, BT state) are all dark when bluetooth modules are in sleeping status, or

working at parameter setting mode.

3) ChargeIndicator

Turn on if exterior power supply came in, else in dark status.

5. IntroductiontoBluetoothmodulesetting

Bluetooth module is a hardware device insert to inverter’s RS232 port. Bluetooth RS232 Conguration is a pa­rameter setting software for Bluetooth module. It can set Bluetooth module device name, ow control method,
Bluetooth encryption password (pair code), etc.

5.1 MaininterfaceofBluetoothRS232Conguration

Fig 5.1 Bluetooth RS232 Conguration main interface

Port Num: Serial port number of computer

Flow Control: Select None

Device Name: Bluetooth name display on RADIUS Log Light

Baud rate: Default baud rate is 9600 baud.

Class of Device: The communication pair of Bluetooth must have a same class code. If not, set master

device to ox000000, then slave device can set to any you like.

Master: Set as a master device. If devices communicate via Bluetooth, it required one is master

device, the other one slave. Bluetooth modules are working as a slave device.

Encryption: If ticked, the pair devices must use password to communicate with each other, data trans-

ferred will encrypt as well.

Bind Addr: Bind address, whether bind to a pair device. If ticked, Bluetooth module can not be con-

nected by other Bluetooth device any more. If not ticked, it can connect by any Bluetooth
device.

Bound BD Addr: Inquire bound address by click “Search Device”

Clear: Clear Bluetooth pair address saved before. When connected to another address, Bluetooth

module saved it address. That hold back other Bluetooth devices’ connect attempt. By do­ing the clear operation, the module can connect to other devices again.

5.2 WireConnection

Here is connection diagram between Bluetooth module and RS232 serial port from computer.

RS232 wire

Fig 5.2 Connection diagram

Use a RS232 wire to connect Bluetooth module and computer RS232 port.

The problem is both computer port and Bluetooth module port are female RS232 port

, so a wire

with both two male RS232 port

is needed.

5.3 SetBluetoothencryptionpassword

There are two operating mode of Bluetooth module: parameter setting mode and communication mode. You
can switch modes by pressing the small button on module. You must let Bluetooth module working in param­eter setting mode before set parameter. After set nished, press the button to switch module to communication
mode again.

Follow the following step to check or set encryption password

1) Connect Bluetooth module to computer by RS232 wire.

2) Press module mode button to switch module to parameter setting mode.

3) Run Bluetooth RS232 Conguration software, select correct serial port number and select ow con­trol to “None”.

4) First Click “Query” to check the existing settings.

5) Then tick encryption check box and input password.

6) Click “Set” to apply, and wait for setting nish.

7) Click “Query” to check the setting result.

8) Press module mode button again to switch module to communication mode.

6. Q&A

1) Why my RADIUS Log Light can not connect to inverter (with Bluetooth module)?

1. Encryption password (pair code) is different. Check Bluetooth module’s encryption password by

“Bluetooth RS232 Conguration”. ENTER “Set BT code” interface and inquiry RADIUS Log Light
module’s password. Check and correct it to the same.

2. Bluetooth module is in parameter setting mode (the 2 Bluetooth indicator lights all dark). Press the

small button to allow module run in communication mode (the 2 indicator lights all blink).

3. If problem still exist, entry “Reset COMM” interface and reset RADIUS Log Light module.

2) Why RADIUS Log Light can’t write data to SD card?

1. There is a write LOCK switch in the side of SD card. Check if SD card have been locked, switch

LOCK to another side.

2. Check your Bluetooth module number has been set correct. You must set it to actual Bluetooth

number used.
