> This page is not the authoritative source for design information. The official [IS3720 datasheet](https://www.inacks.com/is3720) published on [www.inacks.com](http://www.inacks.com) is the authoritative reference: always consult it for the latest information.

The CATEGORY register block numerically identifies your device type according to the Table 2: RDM Standardized Product Categories. This values are common for all RDM devices.

This value appears on the lighting operator’s console, helping to identify and operate the lighting system. It is for informational purposes only and does not affect RDM or DMX device operation.

The CATEGORY number is a 16-bit register block composed by two 8-bit registers. Register address 527 is the high byte and register address 528 is the low byte.

This register corresponds to the RDM parameter 0x0060 DEVICE\_INFO.PRODUCT\_CATEGORY.

This register block can be read and written via I2C and read via RDM.

This is a non-volatile register block. On each power-up, it loads its last stored value. Writing the same content to non-volatile memory that it previously held does not trigger a write cycle; therefore, it is safe to write to this register at every startup of your firmware.
