1. INTRODUCTION
1. INTRODUCTION
The MCX-600 is a microprocessor controlled wireless repeater,
designed to relay digital data between wireless PowerCode
transmitters and a target PowerCode receiver. Repeater links are
required when the target receiver is beyond the range of at least
some of the wireless transmitters and is therefore incapable of
receiving transmissions directly (see Figure 1).
If the distance between the transmitters and the target receiver is
too large to be covered with one repeater, several auxiliary
repeaters may be added along the communication path. This
way, a multi-level network is created (see Figure 2).
Up to 16 auxiliary repeaters can be positioned between the
farthest group of transmitters and the target receiver. Each
repeater must be assigned a correct LEVEL TAG for the system
to operate properly.
The repeater closest to the receiver is LEVEL 0. As repeaters are
added, the level number increases, up to LEVEL 15 (maximum).
Figure 1.
Single-Level Repeater Configuration
A receiver module, a transmitter module and a
controller motherboard are the building blocks
of the MCX-600. All 3 units are packaged in
a small-size, easy-to-install plastic housing.
Both
receiver
and
transmitter
use
short,
down-
hanging wire antennas. The MCX-600 is
powered by 13 to 20 VDC supply or 11-16 VAC.
A 9-Volt nickel-cadmium rechargeable battery
provides backup in case of power failure. The
battery is recharged by a built-in charger.
A fully charged 120 mAh battery allows emergency operation for 2
to 5 hours at 1:1 receive/transmit ratio (see Section 2 for details).
The MCX-600 is not compatible with CodeSecure™ devices.

3.1 Repeater IDs
PowerCode transmitters use 24-bit ID codes, randomly selected
in the factory from over 16 million available combinations. When
a PowerCode transmitter is keyed on, its code is received by the
repeater and retransmitted to the target receiver.
Each MCX-600 repeater has its own unique, factory determined
24-bit PowerCode ID, that is only utilized for reporting the
repeater's own service messages (see Para. 3.4).
3.2 Single Repeater Links
In many cases, a single repeater is enough to bridge the communi-
cation gap between the deployed transmitters and the target
receiver. In a single repeater setup, all 4 levers of the on-board
DIP switch level selector must be set to OFF - i.e. LEVEL 0.
A repeater at LEVEL 0 will simply re-transmit any received
message, without adding its own level tag (which is only
significant in multi-repeater networks - see Para. 3.3). Refer to
Section 4 for detailed communication routine.
3.3 Multi Repeater Networks
A. The Multi-Level Concept
An auxiliary repeater positioned somewhere along the communi-
cation path retransmits data received from any higher level
repeater to any lower level repeater, but may also be used to
retransmit data received from transmitters deployed near it, in its
local coverage area (see Figure 2).
Data flows from the highest level repeater through intermediate
repeater links to the lowest level repeater (LEVEL 0) and finally
reaches the target receiver.
By virtue of differences in message format and the level tag (see
Figure 3), each repeater in a multi-level network can distinguish
between signals coming from nearby transmitters and signals
coming from higher or lower level repeaters. The repeater's
response is based on this distinction.
