WARNING
SAFETYPROCEDURES
Safety is an extremely high priority in every remote control system designed and
manufactured by Remtron. Although every effort has been made to provide a product
with the most complete array of safety features, each application has its own unique
requirements.
Remtron and its agents cannot be held responsible, for any breach of safety,
carelessness, improper or unauthorized use of the remote control system or the
equipment it is intended to control. Each customer is responsible for safe and proper
use of the equipment. Each customer is also responsible that the employees involved
with this equipment know, understand and use proper installation, operating and
maintenance procedures and that they are aware of and adhere to all established
safety rules and regulations as they apply.
1.1 INTRODUCTION
The RCS200 is a digital remote control system
for applications that require a high level of reliability
and integrity. It is designed for short range, license
free operation of industrial and commercial
equipment.
Intended primarily for OEM applications, the
number of functions and the receiver interface is
determined by the user's application.
1.2 SYSTEM DESCRIPTION
The basic system consists of an RCT200
Transmitter and an RCR200 Receiver. The signal
format consists of a Amplitude Shift Keyed (ASK)
signal that carries a 24 bit address, 8 data bits
and is verified through a 16 bit CRC check word.
Data is transmitted using Manchester format at a
4800 baud rate.
The address is permanently programmed into the
transmitter at the factory and cannot modified. The
receiver uses a learn mode to copy the address
code from a transmitter and store it in memory.
1.3 TRANSMITTER DESCRIPTION
The transmitter is housed in a plastic case with
membrane switches for control inputs. Inputs are
encoded by a microprocessor and transmitted
using burst mode ASK.
Figure 1-1 shows a block diagram of the
transmitter. When a switch is activated, power is
applied to the transmitter. The microprocessor
encodes and sends a packet containing the
address, data and CRC check word to the
Transmitter IC. The packet is repeated every 60
m-sec as long as any switch is activated. When
all switches are released, power is removed from
the transmitter.
The transmitter IC is an integrated frequency
multiplying PLL with a power output stage. It uses
a fixed ÷32 prescaler so the output frequency is
set at 32 times the reference crystal. The
transmitter antenna consists of a matched loop
on the circuit board.
