Wireless Control Systems are designed for control of industrial and commercial
equipment. These rugged controls are built to survive the wear and tear of life in factories, mills, and
construction industries. The 23 Series is designed especially for the mobile markets. 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 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 from 12 VDC vehicle power. Operation from
24 VDC is also available.
2.1
ID Codes
Each transmitter and receiver can be programmed for any one of 81 operating frequencies, plus a 16-bit
address code. A single ID Code is used to set and identify both the frequency and address. There are millions
of codes so that no two systems will ever be assigned the same code unless specifically requested for a
particular application.
Each system is fully programmed and tested before shipment from the factory and should require
reprogramming only in the case of spare management (see
Maintenance
).
2.2
Programming
One of the key features of the decoder is Laird’s exclusive Manufacture Application Program (MAP). The MAP
determines how the outputs are directed, what type they are, how they operate, what safety criteria is
required, and what processing time should be used for each one. In short, the MAP allows Laird to match the
control requirements of almost any system. Laird programs the MAP at the factory.
2.3
Programming Accessories
A stand-alone, portable, and handheld programmer, RAC16A, is available for most applications. It provides a
convenient method for changing the ID Code and making basic application changes to transmitters and
receivers.
2.4
AutoLink
Some receivers are provided with the AutoLink system which allows the receiver to copy the ID code from
any of the 23 Series transmitters by the push of two buttons.
2.5
Options
Custom Labels. Custom labels are available from the Laird factory to best suit your application.
Custom Programming. Output relays can be programmed to meet special control requirements.
First-Come-First-Serve (FCFS). The First-Come-First-Serve option allows use of multiple transmitters
with one receiver, one at a time. The receiver scans a preset list of ID Codes. When a valid signal is
received, the receiver stops scanning and responds only to that transmitter’s signal. When the signal is
no longer being received (i.e., the transmitter has been turned off or is out of range), the receiver
again scans until another valid signal is received.
Multiple Receivers Controlled by Multiple Transmitters. One transmitter can control up to a maximum
of six receivers with a rotary selector switch.
Extended Range Antenna. An extended range 900 MHz antenna, Model RCA7, is available for special
applications that require increased range.
Intrinsically Safe. Intrinsically Safe UL-approved systems with NEMA 7 receiver enclosures are available
for ratings of up to Class 1, Division 1, Group D.
