Inputs
The module communicates via a serial UART interface usinggoldpin connectors - 2.54 mm raster. Description of the inputs is given in the table below.
| Pin | Description |
|---|---|
| VCC | Power: 5,0 V. |
| GND | The ground of the system. |
| RO | The output data on a serial bus must be connected to pin Rx of the microcontroller. |
| DI | The output data on a serial bus must be connected to pin TX of the microcontroller. |
| RSE | Direction control outputs/inputs, RS485 bus:
|
| And | Output/ input RS-485 irreverisble. |
| B | Output/ input RS-485reverisble. |
The system has three types of output connectors RS485:goldpin raster 2.54 mm,ARK (screw)andRJ11 (telephone). The location of the telephone connectorcan be configured by soldering jumpers signed on the reverse side of the module.
Jumper configuration on the back of the board.
