Quick Start
This guide will show you all elements that create the GOBLIN 2. You’ll learn how to use it and program it in an easy way to create IoT projects quickly.
1- Download and install the drivers needed at:
www.verse-technology.com\/goblin2\/drivers
2- Plug the GOBLIN 2 into your computer using the microUSB-to-USB cable. Be sure the main switch is in “OFF” mode.
A blue led within the battery module will turn on, meanwhile a red led will flicker (ON–OFF). This means the battery isn’t plugged in.
When the Li-Po 3.7V battery is plugged to the S2H
If there battery is not charged the “Red LED” will remain ON and “Blue LED” OFF.
If there battery is charged the “Blue LED” will remain ON and “Red LED” OFF.
3- Changing the main switch to ON, the “Blue LED” will turn on meaning that the GOBLIN 2 is already on and ready to use. Your PC will assign it a COM port and it’ll be ready to be programmed from the Arduino IDE or Atmel Studio.
4- The functionality of the switch 1 and switch 2 will shown hereunder:
A) Switch 1: In the “D7-D8” position (slide to its right) enables PIN 7 and PIN 8, located in right side bar of the GOBLIN 2 to be used as in or out digital ports and therefore you can plug any peripheral. RS-485 is disabled.
B) Switch 1: In the “RS-485” position (slide to its left) enables the communication port RS-485, this means that the GOBLIN 2 PIN 7 and PIN 8 will be dedicated entirely to communicate with any industrial sensor. Disabling pins as digital IN or OUT as mentioned in section A.
Note: Pin 7 and 8 are declared as “serial por software” when you program using Arduino IDE, then it is explained the software part.
C) Switch 2: In the “PROGRAM” position (slide to its right) enables the programming mode for ATMEL-328P, this way we can communicate with the microcontroller from the PC and therefore upload the programs from the Arduino IDE or Atmel Studio.
D) Switch 2: In the “SIM_AT+” position (slide to its left) enables the communication mode with the SIM5320A from the PC, it is used to send commands AT+ straight from a serial monitor such as Arduino IDE, and so that it can have a direct communication with the cellular network.
5- When the program is uploaded to the GOBLIN 2, the “red leds” (RX and TX) represent the communication status between the Atmel 328 and the PC. When the program is successfully loaded the leds will turn on synchronously starting with the TX led and then the RX one. Setting the switch 2 in PROGRAM (sliding to its right).
6- When you have a direct communication between the GOBLIN 2’S SIM5320A and the PC, the “red leds” (RX and TX) display the status of the communication – the commands (AT+) via the serial monitor within the Arduino ID. Setting the switch 2 in SIM_AT+ (slide to its right).
7- A) The “RESET” pulse button is used to restart the ATMEL328P.
B) The “SIM_OM” button is used to turn on the SIM5320A manually – it can also be turned on setting HIGH and LOW the PIN 5.
8- The “green led” (STATUS NET) indicates that the SIM5320A is ON, and it turns on intermittently right after. This indicates a possible connection with a celular network. It integrates U.FL plugs to connect to GPS or GSM antennas.
9- RS–485 leds, “Red led” turns on when information is sent from the GOBLIN 2 to the industrial sensor, “Green led” indicates a response from the sensor with a RS-485 protocol towards the GOBLIN 2.
