4. Introduction
Cattron CommandPro®Wireless Control Systems are designed for control of industrial machinery. The rugged
controls are built to survive the wear and tear of life in factories, mills, and foundries. These systems comply with
requirements for operation under Part 15 of the FCC Rules and Regulations. This means neither the operator nor
the company need apply or register for a license to operate this equipment.
The Cattron Safety Stop Remote Control System is designed to provide the means for an operator to remotely
stop electrical equipment in times of emergency. The Safety Stop Remote Control System is used as a
supplement to the hard wired Emergency Stop switch on equipment and not as a replacement for such function.
The basic system consists of a transmitter and a receiver. The transmitter sends commands to the receiver by
means of radio waves in the 900 MHz band. Receivers operate at 115 VAC 50/60 Hz power. Operations from 220
VAC, 24 VAC, 12 VDC, or 24 VDC are also available. The receivers feature easy ‘screwdriver’ maintenance,
making troubleshooting and repairs simple. The Cattron CommandPro®Wireless Control Systems are UL-508
approved in the United States and CSA-C22.2 approved in Canada.
4.1 How the System Works
4.1.1 Frequency
Cattron equipment operates in the range from 902 to 928 Megahertz (MHz) band. A wavelength at our frequency
is 12.9 inches.
Like light, 900 MHz radio signals pass through glass and plastics, and will reflect off of walls, buildings, and metal
structures. Unlike light, 900 MHz radio signals penetrate all plastics, including those that you cannot see through,
as well as thin-gauge steel, dry wood, dry concrete, plasterboard, fog and rain.
However, trees, earth, water, people, aluminum, copper and some window tints will not readily pass our signals.
4.1.2 Range and Antenna Coverage
Antennas convert radio signals into radio waves and convert radio waves back into radio signals. They can send
and receive in all directions or in a single direction, depending on their design.
An omnidirectional antenna is like a light bulb, and a directional antenna is like a flashlight. Metal objects reflect
radio waves, just as a mirror next to a light bulb will reflect light. Metal objects near an antenna alter the intended
pattern of an antenna by either shading or reflecting signals.
Our standard antennas are omnidirectional; they ‘see’ equally well in all directions. We have other antennas that
will ‘see’ further in one direction for special applications.
4.1.3 License-Free Channels
The 902 to 928 MHz spectrum is set aside by the FCC as an ISM Band (Industrial, Scientific and Medical), and
this spectrum accommodates many license-free users. We have the ability to change frequencies in this band,
and we have 81 different channels that we can assign to our transmitters and receivers. The actual frequency is
coded into the receiver and transmitter at the factory, but it can be changed to one of the other 80 channels in the
field.
Other devices in this band include wireless phones, computer data links and inventory equipment. As a condition
of using this band, our products must accept and handle interference from other users.

CommandPro®General Purpose & Safety Applications
User Manual

9M02-9028-A031-EN
Rev 4
The 900 MHz band has worked well for most users, and not being burdened with licensing regulations is often
desirable. The FCC has allowed 50,000 microvolts per meter field strength on this band, which is 250 times
higher than other unlicensed frequencies below this band. This allows our systems to operate very reliably in the
presence of other signals.
4.1.4 Command Format
We use packet-mode, Frequency Modulation (FM) to carry commands in a packet form from our transmitter to our
receiver.
To reduce battery drain, our transmitter transmits for a hundredth of a second, which is long enough to send one
packet to our receiver at a repetition rate of either 16 or four times per second.
The rate varies: 16 times per second for three times when sending a command and four times per second when
there is no change in commands and the transmitter is still on. Any time a lever or switch is activated, we send all
control settings three times at the 16-per-second rate and then return to the slower rate of four times per second.
Our receiver uses the slower rate for maintaining transmitter timing and provides for a maintained link where one
is used. The only exception to this is the ‘STOP’ switch, which transmits at 16 times per second as long as it is
depressed. In addition to lever and switch positions, each packet contains a unique address and CRC check sum
(described in the next section).
4.1.5 Safety
Safety and preventing loss of control are very important issues at Cattron. We use a unique identification code for
each user. There are provisions in the system for 65,535 individual codes.
Each transmission includes a CRC check sum, which is a polynomial created by factoring all of the previous bits
transmitted. Once the receiver receives a valid start command from the transmitter, the receiver tracks the time of
the transmitter and ignores all other transmissions that do not fall within the expected time frame of the
transmitter.
Maintained link systems must receive at least one valid transmission each second in order to allow the remote-
controlled equipment to function. The receiver provides a loss-of-signal control output that safely shuts down the
equipment if a loss of signal occurs.
The receiver will not allow restart of equipment under its control after a loss of signal until a valid system start
command is received from our transmitter. This prevents an unintended start-up from occurring if the transmitter
returns within range of the receiver and is still operating.
The transmitters also check the position of all controls upon start-up. The transmitter will not issue a start
command if any of the controls are pressed at the time the start command is invoked.
4.1.6 Monthly Inspection Schedule
It is recommended that the following tasks are performed once a month:
•Inspect the transmitter for damage to keypad and case
•Inspect all electrical and antenna connections to ensure they are clean and tight
•Ensure all terminal strips are firmly in place

Refer to the applicable section (TRANSMITTER or RECEIVER) for details on transmitter and receiver testing and
repairs.
4.1.8 Programming
Each transmitter and receiver can be programmed for any operating frequency, address code and specific
operating parameters required by the particular system. Each system is fully programmed and tested before
shipment from the factory and should require reprogramming only in the case of managing spare transmitters.
4.1.8.1 Programming Hardware Requirements
The RAC16A Series Programmer is available for most applications. It provides a convenient method for changing
the identity code and making basic application changes to transmitters and receivers.
4.1.8.2 Programming Levels
Most programming changes involve only the assignment of the identity (ID) code. All programming levels,
including those that allow changing time constants, relay assignments and decoding logic are covered in the
RAC16A Series manual.

5. 22 Series Transmitters
5.1 Transmitter Description
This section describes the safety/operational features, troubleshooting and repair of the 22T10A transmitter.
Cattron control transmitters are housed in a rugged polymer plastic IP67 compliant case that stands up to
extremely rugged use. A key feature is our patented switch assembly for control inputs. This long-life elastomeric
keypad is ergonomically designed to provide easy operation over long periods of time with exceptional reliability.
A leather holster is provided for added protection.
All transmitter functions are controlled by a microprocessor with a special memory for configuration information.
This offers a great degree of capability and versatility, while at the same time providing simplicity of operation and
maintenance.
The antenna is internal to the transmitter case, protecting it from damage. A self-test LED indicator provides a
quick visual check of transmitter and battery status.
5.1.1 22T10A (Maintained Link Mode)
While the system is in operation, the transmitter maintains an active radio link to the receiver at all times. When
the transmitter is on, a periodic data packet is sent to the receiver to keep the receiver safety active. When any
switch is pressed, three rapid commands are generated to ensure a fast system response. The transmitter then
reverts back to the slow rate to conserve battery power. The transmitters are designed to be very efficient. Two
AA batteries provide power for the transmitter.
5.1.2 22T10A (Utility Mode)
When any switch is pressed, rapid commands are generated to insure a fast system response. When any switch
is released, three additional switch release commands are generated. If no switches remain pressed, the
transmitter stops transmitting.

7. Receivers
7.1 Receiver Description 22R08A
The 22R08A receiver consists of a single RF/Relay Board mounted inside a NEMA 4 enclosure. In utility mode,
the 22R08A has eight control relays. Typically, in maintained link mode, the 22R08A receiver has eight control
relays configurable to customer applications and requires a continuously valid signal from the transmitter for the
system to operate. Figure 5 shows the general arrangement of the receiver.
7.1.1 RF/Relay Board
The RF/Relay Board contains the radio receiver, the microprocessor-based control system and the output relays.
Operating in conjunction with the microprocessor, signals are received by an advanced, synthesized RF module.
Commands are received on one of 81 possible frequencies and are checked against a 16-bit address code for
proper identity and further tested against a 16-bit CRC check. This ensures only valid information meant only for
the particular unit is decoded.
The microprocessor contains a programmable memory that retains the frequency, address and particular
operating parameters for the system. The receiver is field programmable by using a portable RAC16A Series
Handheld Programmer. For convenience, the interface terminal strips are unpluggable. The relay board can be
easily removed without the necessity of tracking wire numbers and positions.
7.1.2 Safety Features
Controlling heavy industrial equipment requires that the wireless control system be reliable with built-in safety
features. Each transmission goes through several checks to ensure that the information being received is error
free. Millions of combinations of frequencies and address codes mean that no two systems will ever be produced
with the same frequency and address code.
The 22R08A receiver may be configured with a safety interlock that is controlled by the microprocessor only in
maintained link mode. If for any reason valid data is not being received for more than one second, all relays will
open. In addition, all relays are opened any time an operator sends a STOP command.
7.1.3 Receiver Diagnostics
While the 22R08A receiver is technically very complex, it is exceptionally easy to maintain and troubleshoot.
Diagnostic LEDs plus an LED for each output relay are all that are required to isolate a problem should one occur.
The receiver assembly monitors and indicates its status on a continuous basis.
