Using a standard USB cable to connect the machine, and when "STMicroelectronics
Virtual COM Port ..." can be seen on the computer equipment manager ports (COM &
LPT), it suggests that the USB driver is installed correctly and the device is connected
properly.
Connect the PC with standard RS232 cable
RS232 interface is shown below.
Figure 2-41 RS232 Interface
RS232 interface parameters configuration:
Baud rate: 115200
Data bits: 8
Stop bit: 1
Parity bit: NONE/10MHZ
Note:
Do not use USB and RS232 interfaces simultaneously. The instrument will lock the port after
receiving data, and if using them simultaneously, it may lead to the other ET3310 unworking or
working abnormally.
