## Modbus RTU Registers The EZ-LIGHT uses the holding registers table for providing read/write access to configuration data. The holding registers are defined in the 40000-49999 address range. The input registers table is used for providing read-only access to system status data. The input registers are defined in the 30000-39999 address range. EZ-LIGHT employs a direct addressing scheme. For example, the input register at address 30000 is accessed by reading address 30000 (0x7530) directly; the starting address is not an offset. ## Supported Modbus RTU Functions **==> picture [500 x 107] intentionally omitted <==** **----- Start of picture text -----**

Construction Housing: polycarbonate Translucent dome: polycarbonate Mounting Nut: PBT ## FCC Part 15 Class B for Unintentional Radiators (Part 15.105(b)) This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: - Reorient or relocate the receiving antenna. - Increase the separation between the equipment and receiver. - Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. - Consult the dealer or an experienced radio/TV technician for help. (Part 15.21) Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate this equipment. page 6 of 8 © Banner Engineering Corp. All rights reserved. www.bannerengineering.com 10-Jun-25 EZ-LIGHT® K50 Modbus Series Multicolor Indicators ## Industry Canada ICES-003(B) This device complies with CAN ICES-3 (B)/NMB-3(B). Operation is subject to the following two conditions: 1) This device may not cause harmful interference; and 2) This device must accept any interference received, including interference that may cause undesired operation. Cet appareil est conforme à la norme NMB-3(B). Le fonctionnement est soumis aux deux conditions suivantes : (1) ce dispositif ne peut pas occasionner d'interférences, et (2) il doit tolérer toute interférence, y compris celles susceptibles de provoquer un fonctionnement non souhaité du dispositif. ## Dimensions All measurements are listed in millimeters [inches], unless noted otherwise. The measurements provided are subject to change. **==> picture [500 x 488] intentionally omitted <==** **----- Start of picture text -----**
