About OEM codes

The OEM Code or Own Equipment Manufacturer Code is a 16-bit number that uniquely identifies an Art-Net product. OEM Codes are administered by Artistic Licence.

The OEM Code is usually expressed as a 16-bit hexadecimal number, pre-pended with ‘0x’. For example: 0xabcd

The hexadecimal format is also written with a subscript 16: abcd16

It can also be expressed as two decimal numbers separated by a hyphen. For example: 171-205

These two formats are interchangeable as hexadecimal 0xab is decimal 171 and hexadecimal 0xcd is decimal 205.
