Description

Converter allows you to connect the microcontroller via the RS-485 bus which supports up to 32 devices on a line with length up to 1 km and a speed up to 10 Mbps. The module is based on a SP485 fitted with connectors:goldpin, raster 2.54 mm- for connection with the microcontroller using the serial interfaceARK andRJ11for RS485 bus.

Konwerter UART

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:

  • High - bus output on.
  • Low - bus input on.
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.
