What is the significance of the wires of the 18-pin interface connector found in GV600 Asset Tracker?
The GV600M Tracker has an 18-pin interface connector that contains the connections for power, I/O, TTL. The sequence and definition of the 18-pin connector are depicted in the following figure:

The below table has Standard Cable Color definitions for wires of GV600MG:
| Pin No | Color | Definition | Comments |
| 1 | Red | PWR1 | Primary Power 8-32V |
| 2 | Red/Green | RWR2 | Secondary Power 8-32V |
| 3 | Black | AGNG | Primary Analogue Ground |
| 4 | Black | AGNG | Secondary Analogue Ground |
| 5 | White | IGN | Ignition Detection Input, Positive Trigger |
| 6 | Green | ADIN1 | Analogue Input 0-32V |
| 7 | Red/White | OUT-3V3 | External Accessory Power 400mA Max |
| 8 | Black/White | GND | External Accessory Ground |
| 9 | Gray | 1-WIRE | Temperature Sensor Input |
| 10 | NC | NC | NC |
| 11 | Blue | OUT/IN1 | Negative trigger input1 for normal use or Open drain output1 150mA max drive current |
| 12 | Yellow | OUT/IN2 | Negative trigger input2 for normal use or Open drain output1 150mA max drive current |
| 13 | Brown | OUT/IN3 | Negative trigger input3 for normal use or Open drain output1 150mA max drive current |
| 14 | Orange | OUT/IN4 | Negative trigger input4 for normal use or Open drain output1 150mA max drive current |
| 15 | Purple | EX_RX | UART RXD RS232 |
| 16 | Purple/White | EX_TX | UART TXD RS232 |
| 17 | Pink | RXD | UART RXD TTL |
| 18 | White/Black | TXD | UART TXD TTL |
Note:
- The main color of the dual-color cable is the first color, for example, Black/White means black is the main color, and white is the secondary color.
- In Azuga we currently support only 2 wires: Red - Power, Black - Ground.
