 | Characteristics |
Design
| 1. LED status display |
| 2. Power supply and communication interface |
| Area of application | Identification tasks on small assembly lines in harsh industrial environments. Mainly used in 3C, new energy and other industries |
2. Electrical Interface
KRH-M30G with RS-232 interface, using a 4Pin-M12-ACODED-Male connector, the pin assignment is shown below.
 | Pin | Assignment | Description |
| 1 | +24V | Power supply positive |
| 2 | TX | RS-232 TX |
| 3 | 0V | Power supply negative |
| 4 | RX | RS-232 TX |
3. LED operating display
The operational statuses of the reader are displayed by the LEDs. The LED can adopt the colors blue and the statuses off, on, flashing.
| Name | Color | State | Description |
| SYS | Blue | Off | The reader is power off. |
| On | The reader is powered on and working properly. |
| 20Hz flashing | Tags was detected in the main identification area (RSSI signal is the strongest). |
| 8Hz flashing | Tags was detected in the secondary identification area (RSSI signal is medium). |
| 4Hz flashing | Tags was detected in the critical identification area (RSSI signal is weak). |
| 2Hz flashing | Valid instructions were received and executed successfully |
4. Reliable identification area
The tag should be in the center area of the sensing range as shown below.
5. Metal-free area
The KRH-M30G can be flush-mounted in metal. Allow for a possible reduction in the field data. To avoid any influence on the field data, the distance "R" should be kept to ≥40mm.
In order to avoid potential conducted interference, it is recommended to use nonmetallic brackets to cut off the transmission path of conducted interference.
6. Minimum distance between KRH-M30G readers
KRH-M30G side by side,to avoid any influence between the readers, the distance "D" should be kept to ≥80mm.
KRH-M30G face-of-face, to avoid any influence between the readers, the distance "D" should be kept to ≥150mm.
