36M & 72M Startup Sequence

Firmware Version

The firing module displays the firmware version of the device first, such as “5.0.2.” All devices synced together must use the same firmware version.

To learn more about firmware versions and how to upgrade your system, at no cost, please see Firmware Figured Out.

Self-test

“tSt” displays as the firing module performs the following tests:
Cue responsiveness – Tests the responsiveness from each cue, ensuring each firing MOSFET turns on and off. If any cue is unresponsive, the system will display Er1 or Er2.

LED function – With the key in the TEST position only, the red and green LEDs will flash briefly.

Shorted/stuck button – During the self-test, if any button is pressed a false-positive to the shorted/stuck button test will occur, and error code Er3 will display.
