Functional Description

Introduction
Cattron MP Series Portable Remote Control (PRC) systems offer the security, reliability and flexibility required for
harsh industrial control applications, coupled with the speed of either three high performance microcomputers
(MP96 Series) and two high performance microcomputers (MP48 Series). While the MP96 Portable Remote
Control System represents the top of the Cattron line, the MP48 Series PRC System offers the same security,
reliability and dependability required for operating machinery in harsh industrial environments, but with fewer
features.
All MP systems are individually custom-designed for a specific application at our Cattron facility. No two PRC
system applications will be identical.
A single board receiver is under the direct control of a variety of lightweight, hand-held style control transmitters.
Received signals are routed to a single board decoder that contains three microcomputers (
control
,
secondary
,
and
data
). Although each microcomputer is programmed for separate tasks, all three microcomputers
communicate with each other when necessary, providing a high degree of ‘back-up’.
Taking the MP96 system as an example, the
control
microcomputer receives incoming data that has been
processed by the receiver. It decodes the incoming data, checking for all the correct addresses, data and error
check bytes.
The
secondary
microcomputer receives the same data as the control microcomputer and independently decodes
the data, making a separate validity check.
The
data
microcomputer stores event data in a log with date and time stamp information for download or display.
All Cattron MP96 systems allow for up to 65,534 unique addresses for each RF channel. Typical systems use one
of 126 addresses.

Component Identification
Figure 1 identifies the major components of a typical MP Series receiver/decoder. Note that the system illustrated
is a generic configuration as normally provided for crane remote control applications. While the electronics
chassis (containing the power supply, receiver and decoder boards) is common to all MP Series systems, there
may be some physical differences between the illustrated system and your actual system. Notably, such
differences may be in the type or size of the NEMA/IP enclosure, and the quantity, location and configuration of
the relay output boards and hardware contained within.
