600H SERIES OPERATOR MANUAL CONTROLS AND OPERATING PROCEDURES
Do you use amplitude modulation (AM) or fre-
quency modulation (FM)?
FM is utilized. FM is a must in electrically noisy environments. These
environments include areas with welders, power lines, industrial
machinery, etc. A good analogy is a standard automobile radio. In the
above mentioned areas, the radio will have static on AM stations. Your
FM stations assure definite clarity and a common extended range.
Will our current 2-way radio affect the operation
of the wireless controller?
No. Two-way radios are assigned to different bands in the frequency
spectrum and at high frequencies. At the lower frequencies such as 49
MHz, the power density in a given area is much lower than at higher
frequencies therefore much less chance of interference.
Is the unit affected by outside interference? Any receiver will receive frequency to which it is tuned. Should the
radio remote unit receive an interfering signal which is at the same fre-
quency, the “Smart Logic” analyzes the incoming signal to determine
validity. First, it must be a digitally modulated FM carrier, it must have
the exact data stream length and appropriate baud rate. The data
stream length totals 120 bits of information. The baud rate is the speed
at which these bits are transmitted. The first 120 bits are stored and
compared to the next consecutive 120 bit data stream(s). Each of
these 120 bit data streams are broken down into groups of bits called
data words or bytes. These bytes reflect each individual switch and/or
position along with additional information of the transmitter. Also
included is an address code that must match the codes of the appropri-
ate transmitter. If any bits of this data stream are wrong or missing the
outputs will not be updated. Should there be a possible interfering sig-
nal present, normally the wireless transmitter is operated at a closer
range than the interfering signal and the receiver will perform properly
since it will pick up the strongest signal.
Will two radio remote units in the same vicinity
operate each other?
No. Each receiver and transmitter have address codes which are set
by the factory and are shipped as a set. Therefore, serial numbers
should be recorded for future reference should assistance from the
factory be necessary.
Is the unit protected from environmental condi-
tions?
Yes. The unit is operable in temperature ranges from -25°F to +150°F
(-32°C to +66°C). Placement of the receiver is recommended to be in
the cab or tool box. The printed circuit boards in both the receiver and
transmitter are coated with conformal material for protection against
high humidity and moisture. The transmitter may be used in rainy con-
ditions, do mot submerge the unit in water for any prolonged period of
time. Should water get inside, remove top cover of transmitter and
allow components to air dry. Replace battery, reassemble and continue
use.
What type of battery is used? A standard alkaline 9 volt battery is recommended. The Duracell Cop-
per Top is a representative battery that fits the battery enclosure cor-
rectly and provides an acceptable service life.
How long will the battery last? This will depend on the frequency and duration of use. Customers who
use their wireless controller extensively have indicated a span of 4 to
10 weeks.
