 05/18/2017    1031 QolorFLEX 5722&5742      

The latest firmware for 5722M and 5742M require minimum level of firmware installed in the 5792M SHoW DMX Neo Max radio module.  

Candle PWM Dimming 

CTI added a 100uF 10V electrolytic capacitor (City Theatrical part number 101-00059) between J7 (+) and J3 (-) on the candle PCB. Set your dimmer PWM output frequency to 1KHz or 1.2KHz, depending on model. 

 12/1/2018    1032 Firmware for QolorPIX Tape Controller, Eight Output                        

The QolorPIX controller can experience a screen lockup after numerous keypresses while navigating menus. The lockup will periodically persist through a power cycle. The 5850 Firmware update fixes these lockups.

 12/1/2018    1033 QolorStrip Wireless LED Strip and Charging Case                        

When a QolorStrip fixture is in a charging case, the LEDs glow to help indicate charging is in progress. Maintaining this state while charging can lead to LED and driver IC failure. Removing the magnets from the charging case will prevent the LEDs from glowing without preventing the unit from charging. Charging status can still be observed from the LCD.

 12/1/2018    1034 ColorSource SHoW DMX Compatibility                        

ETC’s ColorSource wireless relay system uses 5792 SHoW DMX Neo radio module firmware v3.3.x to be compatible with ETC’s RDM network. City Theatrical’s SHoW DMX product line uses 5792 firmware 2.13.x. When the two systems are intermixed, compatibility issues may appear. To correct this compatibility issue, it is recommended to upgrade CTI product to radio 5792 firmware 3.3.x. See details in Tech Bulletin 1032.
