GTW-BL100 WIRELESS GATEWAY

The GTW-BL100 Wireless Gateway is designed to receive encrypted data packets from compatible Bluetooth enabled industrial sensors and to route the data to a MQTT Broker over Ethernet.

COMPATIBLE SENSORS

INTERFACES
The Gateway contains 3 tactile push buttons and 4 status LEDs on the top of the unit.

Fault

|

Red

| Blinks every 2 seconds when a fault is detected with either the Ethernet connection or

connection to the MQTT Broker.

The specific fault will be

displayed on the serial terminal. Automatically clears when the

fault is removed.

CONNECTIONS

DC INPUT
The DC input accepts a 2.5 mm x 5.5 mm barrel plug. The Gateway is designed to be operated with the provided AC/DC power adapter (CUI Inc. SWI24-12-N-P6). Input voltage range is 7 VDC to 15 VDC.
ETHERNET
The RJ-45 jack connects to a LAN running a MQTT Broker over Ethernet TCP/IP. The Broker IP address is programmed into the Gateway using the USB connection.
USB
The USB connection is only required to program the Gateway ID and MQTT Broker IP address into the Gateway. The Gateway may be powered from USB, so only this connection is required during
configuration. Note that some diagnostic information is also displayed over the USB connection during runtime.

HARDWARE

CABLE GUIDES Cable guides are provided on the bottom of the unit to route and secure the DC input, Ethernet, and USB cables.

ANTENNA

The Gateway has two antenna ports to support different wireless protocols. The GTW-BL100 only supports Bluetooth, so only the 2.4 GHz antenna is required to be connected. The 2.4 GHz antenna connection is located on the right front of the Gateway.
The GTW-BL100 is designed to operate with the following antenna:

• Manufacturer: PulseLarsen Antennas
• Part Number: W1010
• Frequency: 2.4 – 2.5 GHz
• Gain: 2.0 dBi
• Nominal Impedance: 50 Ω
• VSWR: ≤ 2.0
• Polarization: Vertical
• Electrical Length: ¼ Dipole
• Radiation: Omni

When adjusting the position of the antenna, it is advisable to always rotate the antenna in a clockwise direction. Rotating the antenna counterclockwise may inadvertently unscrew the antenna connector in the enclosure.

MOUNTING BRACKET A mounting bracket is supplied that may be used to mount the Gateway to a wall or other support structure. The mounting bracket slots support 10-32 screw heads.
To secure the mounting bracket to the Gateway, remove the four (4) rubber feet and screw the bracket to the enclosure using two (2) 8-32 × ½” screws.

DEPLOYMENT

1. Program the Gateway (Node) ID and MQTT Broker IP address into the Gateway.
2. Connect the 2.4 GHz antenna to the Gateway.
3. Plug the DC input power to the Gateway. The gateway defaults to power ON. The orange PWR LED will turn ON, and the red Fault LED will start to blink at 2 second intervals. You may also see the red COM LED flash at 5 second intervals.
4. Plug in the Ethernet cable. The Gateway will automatically attempt to establish connection to a MQTT Broker at the IP address programmed into the Gateway. Once connection is established, the Fault LED on the front panel membrane will go out. Note that a green LED on the Gateway circuit card may be visible through the bottom of the enclosure.
5. Gateway is now ready to pair with Bluetooth sensors and to handle data traffic.

PAIRING

These instructions for pairing a Bluetooth sensor to the Gateway should be used in conjunction with the instructions included with the Bluetooth sensor.

1. Place the Gateway in Pairing Mode by pressing and releasing the PB1 pushbutton on the Gateway. The green COM LED will turn on.
2. Follow the instructions for the target Bluetooth sensor to place it in Pairing Mode.
3. If pairing was successful, the green COM LED on the Gateway will turn off. The Bluetooth sensor is now paired with the Gateway and data updates from the sensor will now be received by the MQTT Broker according to the update rate of the sensor. Note that if pairing was not successful, the green COM LED will remain on. To exit Pairing Mode without pairing a new Bluetooth sensor, press and release the PB1 pushbutton on the Gateway. The green COM LED will turn off.
4. To un-pair a Bluetooth sensor from the Gateway, follow the instructions for the Bluetooth sensor.

RESET

The Gateway or BMS may be reset at any time by pressing and holding both the PB1 and PB2 buttons for at least 4 seconds. Bluetooth sensors will need to be re-paired after a Gateway reset.

GATEWAY CONFIGURATION

The Gateway ID and MQTT Broker IP are set via a USB interface to a PC. A serial terminal program (e.g. Tera Term, Hercules) is required. Download links are provided below.
Tera Term: https://ttssh2.osdn.jp/index.html.en
Hercules: https://www.hw-group.com/software/hercules-setup-utility

SET-UP

1. Plug in the USB cable to the Gateway. The Ethernet and DC Input connections are not required. Connect the USB cable to the PC. The USB connection will automatically enumerate as a Virtual (Serial) COM Port. No additional drivers should be required. The Gateway should be visible as a “USB Serial Device” in the PC’s Device Manager (Windows 10). Note the COM port number assigned by the OS.
2. Open the serial terminal program. The following images are for Tera Term. Select “Serial”, and select the COM Port number for the Gateway. Under “Setup”, set the serial port speed to 115200. The default values for data width, parity, stop bits, and flow control should remain as shown.
3. Enter ‘z’ (Lowercase Z) in the terminal window. The Configuration Menu will be displayed.
4. Select option ‘1’ for Programming Mode. Options will be displayed for programming the Gateway (Node) ID and the Broker IP address.

PROGRAMMING GATEWAY ID
Select option ‘1’ from the Programming Mode menu to program the Gateway ID. The Gateway ID must follow the following format:
GTWXXXXXX-YYYY
Where X and Y are numbers. Press [ENTER] to save the new Gateway ID, or [ESC] to exit without saving.
The Gateway will save the new Node ID in non-volatile memory. In order to apply any changes, the Gateway must be reset.

PROGRAMMING BROKER IP ADDRESS
Select option ‘2’ from the Programming Mode menu to program the Broker IP Address. The IP address must be entered in the following format:
XXX.XXX.XXX.XXX
Only the IPv4 address format is accepted. Press [ENTER] to save the new Broker IP address, or [ESC] to exit without saving.
The Gateway will save the new Broker IP address in non-volatile memory. In order to apply any changes, the Gateway must be reset.

READING GATEWAY ID AND BROKER IP ADDRESS

To view the current Gateway ID and Broker IP address, select option ‘2’ (Reading Mode) from the Configuration Menu. The Gateway ID and Broker IP address will be displayed.
The terminal window will automatically return to the Configuration Menu after 10 seconds.

MESSAGE SIMULATION

The Gateway contains a mode where it will continuously send simulated messages to the Broker. These messages can be used to test network operation. The messages are simulated wireless sensor data from a Battery Management System (BMS) and an Asset Tracker (AT).

MESSAGE SIMULATION MODE SET-UP

1. Read the entire procedure before starting.
2. Configure the Gateway and associated applications as instructed in the previous section (Set-Up Instructions).
3. Press and hold the PB1 and PB2 buttons on the Gateway for 5 seconds. The PWR LED should go out.
4. Only release the PB1 button (PB2 is still held down). The PWR LED and Fault LEDs should turn ON, and the red COM LED should start to flash at a fast rate.
5. Release the PB2 button. The red COM LED should stop flashing and go solid red. The Fault LED on the Gateway should turn off.
6. Data should start to appear on both the serial terminal (if connected), and the VA window. The serial terminal displays the raw data, and the VA displays the formatted data.
7. The Gateway will continue to post messages indefinitely. In order to disable message simulation, press and hold the PB1 and PB2 buttons for 5 seconds. The PWR LED should go out. Then release both buttons simultaneously.
