User Manual V5 1 1.1 CT23 Container Tag RFID-LSCAN INTRODUCTION Purpose The purpose of this manual is to describe the operation of the Container Tag CT23 designed to be used in an asset tracking application. The tag features reflect the application requirements for beaconing, excitation and motion sensor integration. For implementation description and detailed functionality please refer to “CT23 Functional Specification”. 1.
User Manual V5 3.2 CT23 Container Tag RFID-LSCAN CT23 Detailed Description of the Operation Modes All modes can be enabled individually and work independently or in any combination. The transmitted UHF message format is the same S23 format for all modes, only the flags fields’ content changes according to the mode. 3.2.1 Excitation Mode. Indicated by the contents of the Control byte. When enabled (WEM=Y), the tag transmits WEP number of messages each time it enters a valid S95, S21 or S23 fields.

User Manual V5 5 CT23 Container Tag RFID-LSCAN REGULATORY COMPLIANCE 5.1 FCC This device complies with part 15 of the FCC Rules. 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.
User Manual V5 5.1.2 CT23 Container Tag RFID-LSCAN Maximum Duty Cycle To comply with 15.231(a) of FCC regulations from average transmitted power point of view, the maximum transmission Duty Cycle for CT23 in Excitation or Motion modes must not exceed 20% in any 100ms time window. The maximum value of duty cycle in CT23 is achieved when 100ms window falls on the Excitation or Motion transmission bursts.
User Manual V5 5.1.3 CT23 Container Tag RFID-LSCAN Predetermined Transmissions Timing To comply with 15.231(e) of FCC regulations, the following rules must be met: a) b) c) total transmission (burst) length must be less than 1 second; Inter-beacon duration must be 30 or more times longer than transmission duration; Inter-beacon duration must be more than 10 seconds.
