!WARNING
LOSS OF CONTROL
•The designer of any control scheme must consider the potential failure modes of control paths and,
for certain critical control functions, provide a means to achieve a safe state during and after a path
failure. Examples of critical control functions are emergency stop and over travel stop.
•Separate or redundant control paths must be provided for critical control functions.
•System control paths may include communication links. Consideration must be given to the
implications of anticipated transmission delays or failures of the link.

FCC NOTICE
This device complies with Part 15. 47 of the FCC Rules.
Operation is subject to the following two conditions:
1. This device may not cause harmful interference and
. This device must accept any interference received, including interference that may cause
undesired operation.
This device must be operated as supplied by the equipment supplier. Any changes or modifications
made to the device without the written consent of the equipment supplier may void the user’s
authority to operate the device.
Exposure to RF energy is an important safety consideration. The FCC has adopted a safety
standard for human exposure to radio frequency electromagnetic energy emitted by FCC regulated
equipment as a result of its actions in General Docket 79-144 on March 13 1996.
This equipment complies with the FCC RF radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated with a
minimum distance of 11cm between the radiator and any part of your body
NOTICE
This symbol on the product or its packaging indicates that this product must not be
disposed of with other waste.
Instead, it is your responsibility to dispose of your waste equipment by handing it over to a
designated collection point for the recycling of waste electrical and electronic equipment.
The separate collection and recycling of your waste equipment at the time of disposal will help
conserve natural resources and help ensure that it is recycled in a manner that protects human
health and the environment. For more information about where you can drop off your waste
equipment for recycling, contact the dealer from whom you originally purchased the product.

Operation
When first installing a coin cell battery, the LED will slowly flash for 5 seconds. While the LED is
slowly flashing on and off the MReX-MB1 will accept configuration commands if connected.
The MReX-MB1 will illuminate the red LED when the button is pressed and remain lit until the
programmed transmission has been sent. If the button is pressed, and held until after the red LED
turns off, the MReX-MB1 will begin to flash on and off for 5 seconds, allowing the unit to accept
configuration commands.
Prior to the normal long LED illumination after the button press the MReX-MB1 may:
•Flash once briefly. This indicates that the battery has less than 30% battery capacity
remaining.
•Flash rapidly for up to 4 seconds. This indicates that the channel is currently busy.
Under normal operation, on start-up there is a sign-on message sent out the 3.3V TTL programming
serial port two seconds after a battery is inserted. The sign on message indicates the firmware
revision, serial number other software related information.
Commands may be issued and firmware updated from this 3.3V TTL serial port. Messages and
frequency can be preconfigured on order, or a serial may be purchased for qualified end user
configuration.
Replace battery if LED does not light after pressing button or if messages are not received.

DMR Messa in
The MReX-MB1 supports the transmission of short Digital Mobile Radio text messages, allowing
direct messaging to many brands of DMR radios.
The MReX has a partial implementation of the ETSI TS 10 361-1 DMR standard allowing for
DMR “Tier 1” messaging and therefore cannot be used in systems that have repeaters.
This is not a full implementation, and as a result has the following restrictions:
•Messages are limited to a maximum length of 50 characters.
DMR messages can be sent when an input is triggered or through use of the WT protocol in a
similar manner as sending POCSAG paging messages. Refer to WT Protocol for usage
information.
The MReX concurrently supports POCSAG and DMR paging, allowing an input to send messages
to both legacy paging systems and newer DMR radios.
Different DMR manufacturers have interoperability limitations. The MReX is similar in this
regard. Please refer to the Specification section for a list of tested DMR radios. The MReX WT
protocol allows for switching between supported radio types to allow support for Hytera, Kirisun
and other brands.

Confi uration
Parameters can be changed using any common serial terminal program. A free serial terminal
program that also allows saving and loading of configuration files can be downloaded from
wte.co.nz/tools.html
Start-up operation is always at 9600:8-N-1.
The MReX-MB1 integrates the MReX-460 module, therefore has available the MReX-460
command set. However, only a subset of those commands are relevant to the MReX-MB1.
Relevant commands are listed below.
All configuration commands always start with the asterisk ‘*’ character.
All messages that do not start with the * character are processed by the protocol decoder.
All messages are terminated by a Carriage Return character, shown in this manual as <CR>
All commands that accept a value, can have that value read back by using the ‘?’ suffix. E.g.
*TX_FREQ?
Returns
*TX_FREQ=460000000 (for example)
No e: It is a good practice to restart the unit after changing configuration. This can be achieved by
removing the coin cell.
