Different from other wireless firing systems, the 18R2 has no limit on how fast you can manually fire cues. This is accomplished by an innovating grid-firing technique where COBRA transmits multiple layers of firing commands that overlap onto each other. This ensures that in the rare event a wireless command is not received, the redundant layers act as backup to ensure every cue is fired as expected.

In addition, you don't need to wait for visual fire confirmation since the COBRA 18M will always provide enough current to fire the cue regardless of how long you hold the button on the hand-held remote.

For manual firing, the 18R2 allows you to fire multiple cues at the same time by simply pressing multiple buttons on the hand-held remote. For example, press cues 1 and 2 at the same time.

In addition, using the USB port for script uploads, you can fire unlimited cues / channels at the same time. For example, if you have 6 positions, where each position has an 18M on a different channel, you can fire each module independently or at the same time.

The 18R2 is outfitted with a USB port for the uploading of up to 100 pre-defined scripts. You can create scripts in seconds using using Microsoft Excel, or you can create powerful pyromusicals using our integration with Finale Fireworks Pro.

Scripts can include everything from mulitple mini-scripts (e.g. quick chases) to complete 15, 30+ minute pyromusicals. You can also create "step scripts" which require the user to manually press the STEP button to jump to the next event.

• Microsoft Excel - The following script format is easily created using Microsoft Excel. You can define one or more scripts in a single file to be executed at any time by any number of trigger channel and trigger button combinations. Using the return channel parameter, you can easily return to a single channel used for starting your scripts for efficient semi-auto firing.

• Cobra Show Creator - Available on PC or Mac, COBRA Show Creator is our own scripting software. You can easily script simple shows, or load a music file to fire events at defined points in music.

• Finale Fireworks - The 18R2 is also integrated to Finale Fireworks, a drag-and-drop visual choreography software for designing firework shows. With Finale, you can watch your show before fired. It also allows for easy integration and timing of music into your shows.

The COBRA 18R2 uses simple controls to allow up to 100 unique channels (200 unique channels on firmware 6.0.0 or higher) to fire from a single remote. Simply change the channel on the remote to fire modules set to the same channel. With 100 unique channels (200 on firmware 6.0.0 or higher) and 18 cues per module, you can fire up to 3,600 unique cues. You can also set as many modules as you want to the same channel to fire multiple positions at the same time. This allows for an easy way to create mirrored fronts or effects.

At COBRA, we believe safety and reliability are the most important features of any firing system. With that in mind, every COBRA system incorporates the below collection of technological and usability based features. This ensures safe and reliable functionality every time you use the system.

• IEEE® Unique Network MAC Addresses - Every COBRA remote contains a fully unique network MAC address. This address is programmed onto the unit at the time of production and contains 16 x 0-F base-16 values. For example, 00.1C.2C.00.00.C0.00.01.

  By syncing a firing module to a remote, the remote's network MAC address is saved and remembered on the firing module, even after power-on and power-off. Once saved, the firing module will ONLY respond to the remote containing this unique MAC address. This prevents any other remotes from firing your system. In addition, any time a firing module is synced to a different remote, the previous MAC address is overwritten, thereby ensuring the firing module only responds to the last remote to which it was synced.

• 2.4GHz tranceiver modules - The Cobra 18R2 uses a 2.4GHz transceiver module manufactured by Synapse, a US company that both develops and manufactures its SNAP line of IEEE 802.15.4 radio modules and transceiver ICs.

  The same transceiver and software development platform is used successfully not only by COBRA, but also in a variety of safety-critical industrial wireless applications, including medical monitoring systems and airport lighting controls.

• Redundant, solid-state, self-testing MOSFETs - The COBRA 18M uses redundant solid-state firing FETs on both the high and low side of each firing cue. This ensures that no power is supplied to the cue unless the firing module is both armed, in fire mode and is actively firing a cue. The redundant FETs provide protection against unintentional electro-static discharge (ESD) and serve to automatically test for damaged or shorted FETs upon system start-up. If detected, the system will automatically disable itself and will not operate.

• NFPA compliant user-design - The COBRA system adheres to National Fire Protection Association (NFPA) chapter 9.2 requirements including a key-operated switch, multiple actions to arm and fire, and minimum current requirements when performing continuity tests.

• Contains FCC, CE and IC certified RF Module - The 18R2 contains the Synpase 802.15.4 2.4GHz RF transceiver modules and is affixed with the CE mark and the FCC mark: "FCC ID: U9O-SM220" per Part 15 regulations.

The 18R2 will last for up to 7 hours in active operation. At any time you can power on the 18R2 to determine the current battery life. When the remote powers on, it will display 1 through 9, this represents the power level, with 9 being full power, and 1 being low power.

The 18R2 is enclosed in 2.5mm thick high-strength ABS plastic. The clear design minimizes entry of air, moisture, and dust into the electronic housing by eliminating the need for cut-outs and micro-gaps in the enclosure. Polyurethane-coated fire-retardant silicon keypads have custom walls that push up against the top-enclosure to further protect against moisture and dust.
