No SN is presented on the exterior of the VPC620.
Use a serial port cable to connect the VPC620 to a PC
to obtain the SN.
A serial port cable is required to connect the PC's
serial port to the camera's serial port. (One end of the cable is DB9 and the
other end is round-headed, as shown in the following figure.)
Step 1. Use the serial port cable to connect the PC's
serial port to the camera's COM IN port (that is, the COM port close to the
power supply, as shown in the following figure).
Step 2. Use a serial port tool on the PC, such as
HyperTerminal and a serial port debugger.
Run the following VISCA commands (serial port type:
RS232, baud rate: 9600):
81 ec 5a a5 01 ff
81 ec 01 06 ff (Obtain the SN.)
