Functional Description.
The CATTRON
®
Metal Keypad (MK) Series remote controller is a lightweight palm sized, extremely
rugged customizable radio control unit for use with any CATTRON
®
Portable Radio Remote Control
(PRRC) System. CATTRON
®
MK series controllers are offered in four family configurations: EZ
(Easy), CS (Crane Specific), AT (Advanced Technology) and UN (Universal).
In all four CATTRON
®
families of MK series controllers, operational security is advanced to its
maximum by the use of a removable stainless steel, electronic i-Key which, when installed to the
controller, defines and enables the appropriate operating parameters. When the i-Key is removed, the
controller is totally disabled.
controller, defines and enables the appropriate operating parameters. When the i-Key is removed, the
controller is totally disabled.
The keypad unit and electronics are contained in an extreme duty, water resistant and dust proof
aluminum housing which has armorized rubber end-caps for switch protection and high impact
resistance. Consequently, the MK series keypad controller is able to withstand levels of impact
previously unattainable by any other portable remote controllers, without the need for carrying cases or
protective rubber housings. The MK controller housing is ergonomically designed with curved bottom
and rubber side grips to allow comfortable handling. The i-Key is mounted in a receptacle located
within the confines of the armorized rubber ‘bumper’ that surrounds the top end-cap. Separate
ON/OFF (green) and STOP (red) switches are also located next to the removable i-Key. A completely
sealed elastomer keypad on the controller front face contains large pushbuttons that are coated with
clear epoxy for additional durability. Each pushbutton is identified by a label that clearly indicates the
specific function for that particular key. When pressed, each pushbutton actuates a function switch
inside the controller and may be of single-step or two-step operation. Also, when pressed, each
pushbutton has a distinct limit of travel, thus providing an enhanced tactile feel that is noticed by the
operator.

All commands from CATTRON
®
MK controllers respond within milliseconds of pressing a
pushbutton and are absolute functions; that is, a positive ON command is sent when the button is
pressed, and a positive OFF command is sent when the same button is released. Additionally, a
mainline ON command is sent when power is turned on and anytime a controller function pushbutton
is pressed. Within the MK controller, a microprocessor performs self–diagnostics, interprets
pushbutton and switch commands, and controls the radio transmitter.

MK controllers are available in single and dual-pressure models. Single-pressure models
offer 4, 8, or 12 pushbutton functions (simultaneous, any combination), while dual-pressure models
offer 6, 12, or 16 operator commanded functions (simultaneous, any combination). In addition, dual-
pressure models provide 2-speed operation and variable frequency drive (VFD) operation with a single
