6Test Setup
6.1 Catena 4801 Test Setup Requirement
6.1.1 ST-LINK/V2 in-circuit debugger/programmer
The ST-LINK/V2 (123001120) is an in-circuit debugger and programmer for the STM8 and STM32
microcontroller families. The single wire interface module (SWIM) and JTAG/serial wire debugging (SWD)
interfaces are used to communicate with any STM8 or STM32 microcontroller located on an application
board.
Figure 12 ST Link Programmer
6.1.2 RS485 Module
This breakout board (123001443) pairs an SP3485 RS-485 transceiver with an FT232RL USB
UART IC to convert a USB stream to RS-485. The SP3485 is a half-duplex transceiver, so it can only
communicate one way at a time, but it can reach transmission speeds of up to 10Mbps. The RTS pin of
the FT232RL is connected to transmit and receive enable inputs of the SP3485, this line is used to
control the transmission mode of the RS-485 transceiver. With the proper drivers installed, the FT232RL
will enumerate as a virtual COM port; the drivers are available for Windows, Mac and Linux.

6.1.3 USB to Serial Cable
USB to Serial Cable (123001121) is used for Configuring the device with TTN and also for monitoring the
device performance on the Serial Monitor.
Figure 14 USB to Serial Cable
Note : The Serial cable configurations are mentioned in the Table 2
6.2 Catena 4801 Configuration

For debugging, the STLink debugger is to be connected with PC, install the STLink debugger driver which
is mentioned Section 5.
After the installation of STLink driver and the upload setup, clone the Modbus-for-Arduino under the
branch catena4801_host and open the example sketch catena_modbus_simple_host. Now follow the
below steps to upload the test sketch using Arduino IDE:
1. Install the latest BSP for MCCI Catena STM32-v2.0.0 to add support for Catena 4801 in
Arduino IDE.
2. MCCI Catena STM32 Boards should be installed from the Boards Manager.
3. Once the board has been installed, Catena 4801 board has to be selected under MCCI
Catena STM32 Boards.
