Running MeshScape Network Monitor
Configuring RS-485 Operation (MN-5409 only)
The RS-485 interface of the mesh node operates using the following parameters:
• Half-duplex mode
• 9600 baud
• Transmitting data: Maximum byte length for one request is 80 bytes
• Receiving data: Reception is terminated by the mesh node when the maximum input byte
length is reached or there is no input for more than 20 ms. Once the input is terminated,
the data is transferred to MeshScape Network Monitor.
The following procedure describes the steps that need to be taken to set up the hardware and
configure a mesh node for RS-485 operation (see
Figure 3-20):
1. Connect the network device to the standard 2-position RS-485 terminal block using the
pinout information provided in
Figure 3-20. The terminal block will accept 26 AWG to 16
AWG wire.
2. From MeshScape Network Monitor, double-click on the desired device from the list of
discovered sensor nodes. The Device window is opened, displaying the device’s current
configuration.
3. From the Digital I/O panel, select Serial Data: RS-485, then Update. The RS-485
connector is ready for operation (digital function is disabled).
4. (optional) To send serial data to the mesh node, enter the data in the Serial Data panel,
then select Send Data.
