Narrowband Photon Pair Source
Chapter 5 Remote Operation from Command‐Line Interface
The Command Line Interface (CLI) provides the user with a method of controlling the SPDC810N remotely over
the USB interface that is emulating a serial port. A standard terminal program (such as Tera Term) can be used to
send commands to the SPDC810N and receive responses.
The virtual COM port settings should be set up as:
Baud Rate: 115200
Data Bits: 8 bits
Parity: None
Stop Bits: 1 bit
Flow Control: None
The list below shows the list of available commands along with a brief description and syntax. Each command
should be sent with a carriage return, or a line feed, or both at the end of the string.
To signify variables, (variable name, format, range) will be used. {Units} will be called out for reference to the
reader but should not be included in typed commands.
