1. Introduction
The Flex 2JB transmitter handset is designed for control of industrial equipment and
machinery such as overhead traveling cranes, jib cranes, gantry cranes, tower cranes, electric
hoists, winches, monorails, conveyor belts, mining equipment, and all other material handling
equipment where wireless control is preferred.
Each Flex 2JB consists of a transmitter handset. Other standard-equipped accessories
include transmitter waist belt, vinyl pouch, pushbutton labels, LED labels, instruction manual CD.
List of notable features include:
* Advanced Controls – the system utilizes dual advanced microprocessor controls with 32bit
CRC and Hamming Code, providing ultra fast, safe, precise, and error-free encoding and
decoding.
* Frequency Hopping RF Transceiver – the system automatically search and lock onto a
free and uninterrupted channel at every system startup or during operation when
encountering radio interference. The system is also capable of two-way communication
between the transmitter and receiver and as well as receiver to receiver with system status
and relay output feedbacks.
* Zero-G Sensor Imbedded – the transmitter is embedded with a Zero-G sensor to guard
against any unintended control of the crane or equipment when transmitter is thrown or
dropped.
* Wireless Remote Pairing Function – system information can be transferred wirelessly
between two transmitters or between a transmitter and a receiver without the hassle of
resetting the spares.
* Reliable Pushbuttons – the pushbuttons have gold plated contacts and are rated for more
than two million press cycles. The defined snap-action steps provide positive tactile
feedback even wearing gloves.
* Low Power Consumption – requires four “AA” alkaline batteries for more than 120 hours of
uninterrupted operation between replacements.
* Durable Nylon and Fiberglass Composite Enclosures – highly resistance to breakage
and deformation even in the most abusive environments. The receiver enclosures and
output cables are UL94-V0 rated. The transmitter and receiver enclosures are IP66 rated.
* Full Compliance – all systems are fully complied with the FCC Part-15 Rules and European
Safety Standards.
* Other Optional Accessories and Features –Ni-MH rechargeable batteries, power adapter.
