1.6 Interface
This section describes the definition and function of each interface in the product.
1.6.1 Power & I/O Interface
The ED-AIC2000 series devices feature a Power & I/O Interface with a 12-pin M12 aviation connector. This interface integrates:
- 1 power input
- 1 serial port (RS232)
- 1 digital input (DI)
- 2 digital outputs (DOs)
The Power & I/O cable connects to this interface:
- One end is terminated with an M12 connector for camera integration.
- The other end consists of bare wires for connecting to power, DI, DO, and RS232 devices.
The pinout definitions for the M12 connector and the corresponding bare wire assignments are detailed in the following table:
M12 Pin | Bare Wire Color | Definition |
| 1 | Yellow | DC- |
| 2 | White/Yellow | DC+ |
| 3 | Brown | COMMON_IN |
| 4 | White/Brown | DI_1 |
| 5 | Purple | Trigger |
| 6 | White/Purple | COMMON_OUT |
| 7 | Red | External Strobe |
| 8 | Black | DO_1 |
| 9 | Green | DO_2 |
| 10 | Orange | RS232_GND |
| 11 | Blue | RS232_TX |
| 12 | Gray | RS232_RX |
| Shell | Black (Thick) | PE |
The 1 DI (Digital Input) and 2 DO (Digital Output) channels correspond to the CM4's GPIO pins, as detailed in the following table:
| Signal | CM4 Pin |
|---|---|
| DI1 | GPIO17 |
| DO1 | GPIO22 |
| DO2 | GPIO27 |
TIP
- The thickest black bare wire is PE.
- For Raspberry Pi HQ Camera, Pins 5 and 7 of the M12 connector are undefined.
- During installation, ensure that wire colors align with pin definitions and properly connect the PE to the ground terminal to guarantee safety and signal integrity.
- If there are unused bare wires during wiring, cut off the exposed metal ends or insulate them with electrical tape.
WARNING
Strictly follow the wiring instructions below to connect the power & I/O cable; incorrect wiring may result in device damage.
1.6.1.1 Power Connection
