| Interface Type | Silk Screen Printing | Pins | Description |
|---|---|---|---|
| Plug-in terminal block | V | 1 | DC power supply +5V power supply |
| G | 2 | DC power supply GND | |
| T | 3 | RS-232 transmission (DAS integrated module transmission, connected to the counterpart RXD) | |
| R | 4 | RS-232 reception (DAS integrated module reception, connected to the counterpart TXD) | |
| G | 5 | RS-232 ground | |
| RF Interface | AOM-RF | AOM RF input | |
| Fiber Optic Interface | Sensor | Connecting sensing fiber, default FC/APC connector | |
| Output Interface | OUT | Module output voltage signal |
Usually you only need to connect pin 1 and follow pin 2 to supply power to the module.
AOM driver is 24V power supply, the integrated module is 5V power supply, do not be mistaken.
Attention
AOM drive power connection, do not stick to cause a short circuit. Drive power connector, "middle is positive, housing is negative"
Do not wire with electricity (fiber optic), easy to burn the connector; fiber optic connector end of use, please cover the protective cover.
