Local Connectivity

MX modules communicate with other nearby modules both wirelessly and through the cables that connect them.
In the diagram below, System A represents MX modules on one pole, and System B represents a linked system
of MX modules on another pole:

Wired local communication between MX modules within a system occurs through the four-conductor inter-
module cables. Trigger activation signals are conveyed via the wired interface along with various other system-
level messages. Inter-module cables also provide flasher modules with power.
Wireless local communication takes place in MX modules in several different forms:
•
MX modules within a system communicate with one another to convey system settings and module
status information. Flasher modules don't communicate wirelessly with other flasher modules.
•
MX power modules from different systems communicate activation and flash synchronization signals.
•
Using the MX Field App, an authorized user's mobile device communicates with an MX power module.
During firmware upgrades, flasher modules can also communicate with the mobile device.
The local communications radio within all MX modules uses 2.4 GHz DSSS (Direct Sequence Spread Spectrum)
with an AES128 encrypted signal. Reliable wireless communication range typically exceeds 1,000 feet (305
meters) between power modules and 75 feet between power and flasher modules but is dependent on local
environmental conditions.
Wireless range between systems can be reduced when power modules' Bluetooth antennas
don't have clear line of sight. Though it depends on other environmental conditions, wireless
range typically exceeds 500ft even when Bluetooth antennas don't have clear line of sight.
Wireless range can also be reduced by the following:
•
Interference from other wireless devices
•
Objects between modules that block wireless signals
•
Nearby objects that reflect wireless signals
•
Heavy rain or snow
In rare cases, unforeseen site conditions can result in poor radio communications
between linked systems. A simple-to-install remote antenna kit is available to
improve local system-to-system radio communications when required. The remote
antenna kit includes a remote Bluetooth antenna, a mounting bracket and an
extension cable so that the antenna can be ideally positioned.
