General System Information.
The Telemotive Radio Control System (system) provides remote control of overhead cranes using radio signals. The
system consists of a hand held portable battery operated transmitter unit and a fixed station receiver unit.
A unique 16-bit code (Access Code) for each system is preset in every transmitter and receiver. The receiver
considers any received signal which does not match the receiver access code setting invalid. The Access Code is
made up of 16-bits (65,000 combinations) and no two similar codes are assigned to any two Telemotive systems.
Up to four systems may be used with the same frequency in a 600-foot area (220 meters). Each transmitter operating
on the same frequency may be operated in close proximity, not less than six feet (1.9 meters), to each other.

TMS Low Power Signaling.
TMS (Time Multiplexed Signaling) is a Telemotive proprietary high-speed packet data system. The system software
is structured to minimize "on the air" transmission time of any transmitter. This allows for multiple transmitters to
share a common frequency. The TMS system is designed so that a transmitter will send a signal for a predetermined
ON time, and then will turn OFF. The length of transmitter ON time is referred to as data burst or packet. The packet
length is a function of the quantity of data to be sent, and the data rate (baud). Once the packet is sent, the
transmitter will turn OFF. This allows for other transmitters to time-share the same frequency when a transmitter has
turned OFF. The TMS system software determines the OFF period and repetition rate of the ON period. Since each
system has its own access code, up to 4 transmitters can share and have equal access to the same frequency. TMS
also allows for reduced battery consumption and extended battery life.
These systems have low power pulsed signaling, FCC certified under Part 15 Telecommunications Code of
Regulations, no license is required. The transmitter unit is frequency modulated, low power and is certified under
the appropriate regulations. A license is not required for the transmitter or operator. Modifications to the RF section
of this system are not permitted and could void FCC certification.
Active ESTOP (an optional feature) causes the transmitter to send confirmation that the ESTOP is not being
engaged via a periodic confirmation signal. Units so equipped will shut down the receiver when out of range.
