5.2. Command mode
Use a COM port terminal in order to communicate with the device. We use the HERCULES COM port soft terminal available to download for free
by clicking on the following link: http://www.hw-group.com/devices/hercules/index_en.html
• With Hercules, select the “Serial” tab, then configure the serial port with the following serial parameters:
Parameters
Value
Rate
115 200 bps
Parity
None
Data
8
Stop Bit
1
• Select the serial port on which the device has been created with Windows (Name).
• Click on the “Open” button to open the serial port.
PLEASE NOTE:
If the com port has been opened correctly, Hercules will display the message “Serial COM3 port opened”.
Alternatively, “Serial port com opening error” will be displayed, meaning either that the com port is already open for another application, or it
does not exist.
• To supply power to the device, move the switch to the right.
Switch ON/OFF
Bottom view
You must send a specific frame in order to move the device to configuration mode.
Frame expressed in hexadecimals: 0xFF 0xFF 0xFF 0xFF 0xFF 0x2B 0x2B 0x2B
For Hercules, this frame must be entered in one of the 3 lines available at the bottom. The hexadecimal format must be expressed using a “$” in
this program, which gives us the following frame: $FF$FF$FF$FF$FF$2B$2B$2B
