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.
