The DXR-702 is a two-channel digital receiver with two isolated
relay outputs designed for use with Linear's DX Format
transmitters. This receiver can be used in a variety of remote
control applications. When the receiver detects a signal from
a transmitter programmed into its memory, the appropriate
relay output activates. The relays have four optional output
BY
configurations. When the relays are set to latch, the receiver
outputs will follow the open/close door status sent from DXT-31
door/window transmitters.
In a typical installation, the receiver is connected to an alarm
control panel, door strike, camera, high current relay or some
other devices. Transmitters are used to activate or control the
devices. The receiver should be mounted with the supplied
mounting bracket indoors or inside a weather resistant
non-metallic housing.
The digital DX code format features over a million possible
codes. The DX transmitters are precoded at the factory to
unique codes, so no field coding is required. For versatility,
any transmitter can be programmed into any receiver channel.
Receivers must be programmed to the transmitter's code before
system testing and operation. Up to 32 transmitters maximum
can be programmed into the receiver. The transmitters can
be split in any number between the two receiver channels.

Receiver channel two is a special channel. If channel two
memory is empty, with no transmitters programmed into it, it
will report low battery signals from any channel one transmitters
capable of sending them. When a low battery transmission is
received, the channel two relay will latch, regardless of how
the option jumpers are set. The relay will remain engaged until
the channel two program button is pressed. The low transmitter
batteries should be replaced before resetting the relay.
The unit can be powered from a 11-17 VDC or 12-16 VAC power
source. The relays' normally open and normally closed contacts
can switch up to 1 amp at 24 volts AC/DC.
Cutting jumpers select how the relays activate. Four settings
are possible. Both relays will function with the same option. The
factory setting causes the relays to engage for four seconds
each activation. Optionally, the relays can be set to engage for
one second, toggle on with one activation then off with the next,
or latch engaged for door status or until reset by pressing the
program button.
A nine-inch wire whip antenna screws into the receiver's antenna
connector. Optionally, a remote antenna (Linear EXA-1000) can
be connected to the receiver for greater radio range. The red
program indicator lights during RF reception. The installer can
verify that signals are being sent from transmitters and diagnose
interference problems by viewing the indicator. The indicator also
lights during memory programming/erasing and flashes to count
the number of transmitters in memory.
