The 72M comes with four banks (A, B, C, & D) that can be channeled independently of each other. Simply press CH+ or CH- on the 72M to set a bank to a channel between 00 and 99 (00 and 199 on firmware 6.0.0 or higher). Press the 'Change Bank' button to toggle between banks and use the CH+ or CH- change the channel for the selected bank. Banks can be set to any channel in any order. For example, bank A can be set to channel 2, bank B can be set to channel 3, bank C can be set to channel 4, and bank D can be set to channel 5. Then, by changing the channel on the 18R or 18R2 hand-held remote, you can fire any bank set to the same channel.

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. Download the script template to begin creating scripts today.

• Cobra Show Creator - Available on PC only, 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.

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 into 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 transceiver modules - The COBRA 72M 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 72M 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 72M contains the Synpase 802.15.4 2.4GHz RF transceiver module.

• Easy to Charge - A charge port and charge indicator exists on the top of the module for simple charging. If you own armored cases, a new faceplate supports charging while the 72M is still in the armored case. Use our single charger or charge up to 5 modules at once with our 5-module charger option.

• External 12-24V DC Input - Rugged external binding posts support external 12 and 24V DC input. For permanent installations, we offer a custom 110/220V A/C to 24V D/C converter. Use the internal LiPo battery pack together with the A/C input to act as a real-time power backup.

• Increased Amperage - Replaceable 9V batteries produce a peak current of 3 Amps. Using the LiPo battery pack, this increases to 6 Amps. Using the external power input, we can produce up to 9 Amps of peak current. This will support firing up to 5 and 16 e-match / clip-on igniters respectively, in addition to also supporting the firing of high current devices such as confetti cannons, flame projectors, and cryo jets.

• Cold Weather Performance - Fire extreme cold shows with confidence with improved cold weather performance down to -20F / -29C.

• Dual Protection Circuits for LiPo Safety - COBRA incorporates dual overcharge, undercharge, and overvoltage protection circuits. The first protection circuit is built into the 72M motherboard. The second protection circuit is built into the battery itself. This means if one of the protection circuits fails, the other acts as a backup. While we don't expect any failures, feel confident that we have designed both the battery and charge circuitry with the highest level of safety and protection in mind.
