Introduction The FLEX SI (Sensor Interface) is a highly adaptable wireless sensor interface for use with the FLEX satellite based asset tracker. The FLEX SI is capable of supporting various combinations of analog, digital, and intelligent Sensor Modules. Examples of Sensor Modules include: tank level sensors, pressure transducers, temperature sensors, door intrusion sensors, event counters, etc. In a typical usage scenario battery life can be expected to multi‐ year.
Wireless Communication The FLEX SI utilizes a 779 to 928 MHz ISM band transceiver. The frequency is configurable to allow for ISM band operation in North America, Europe, and other locales. Transmit power, data modulation, data encoding, and data rates are also configurable to allow for reliable communication in noisy environments. It is recommended to perform a site survey to identify possible sources of interference such that Numerex can make adjustments accordingly.
it is required for the customer to correctly identify and provide the ESN of the FLEX to which the FLEX SI shall be paired. Alternatively, Numerex will provide intuitive software and the required 10‐pin USB connector to perform the field paring. Each FLEX SI shall be labeled with its SID and the ESN of the FLEX to which it is paired. Addendum Certifications FCC FCC ID: TWV‐FLEXSI Part 15 This device complies with Part 15 of the FCC Rules.
Accessory items that can be readily obtained from multiple retail outlets are not considered to be special accessories and are not to be marketed with the equipment. Only those accessory items provided by Numerex have been tested to ensure operation consistent with the regulatory standards that the device is required to perform.
R&TTE 1558 1558 The FLEX SI has been fully tested and complies with all the requirements of EN301 489‐1, EN301 489‐3 and EN60950‐1/A1:2010. Compliance to EN300 200‐1 and EN300 220‐2 has been demonstrated. The FLEX SI is certified to the following safety standards: UL 913, Fifth Edition – Intrinsically Safe Apparatus and Associated Apparatus for Use in Class I, II, and III, Division I, Hazardous (Classified) Locations CSA C22.2 No. 157‐92‐CAN/CSA, 1992.06.
