Configuring a Node’s Operation

Configuring RS-485 Operation (RT-5209 only)

The RS-485 interface of the i-Bean Router 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 router 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 iB-5209 Network Monitor.

The following procedure describes the steps that need to be taken to set up the hardware and

configure an i-Bean Router for RS-485 operation (see Figure 3-10):

1. Connect the network device to the standard 2-position RS-485 terminal block using the

pinout information provided in Figure 3-10. The terminal block will accept 26 AWG to 16

AWG wire.

2. From iB-5209 Network Monitor, select Edit>Devices. The Edit Device window displays.

3. Enter the device ID of the desired i-Bean Router and click Set. The Edit Device window is

now ready to make any changes to the selected i-Bean Router.

4. 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).

5. (optional) To send serial data to the i-Bean Router, enter the data in the Serial Data panel,

then select Send Data.
