By default the device comes pre-programmed to select red on input 1 and white on input 2. There are two jumpers in each device selecting which input bit will activate the red output and which will activate the white output. The cover must be removed from the Tally Helper 500 to use the jumper selectors to program the device to respond to the appropriate bits. Jumpers select which bits will light which color on a given Tally Helper 100. The power supply for each Tally Helper 500 powers the unit and also provides power for the mic tally. Control then loops out of one Tally Helper to the next one in the chain. A NotaBotYet GPIO Breakout for Axia is connected to an Axia GPIO xNode and then a standard cat-5 cable connects the output of that board to the Tally Helper 100. The diagram above demonstrates how it all goes together. Give the odd number of bits in an Axia GPIO port, there is no way to control three mic arm tallies with dual color as it would require six GPIO bits. If two tallies are required to be dual color, then only three tallies can be controlled. For instance, 5 red tallies can be controlled with one port, but if one tally needs red and white, then one port can only control 4 tallies. If dual colors are required, each color takes an additional GPIO bit. One Axia GPIO port can be used to control up to 5 mics arm tallies.
The Tally Helper 100 solves several problems for the installer. The problem is that none of these methods are easy or quick to install. Typical wiring Diagram for 5 Mic Arm Tallies using Tally Helper 100’s However, to use one color or the other, the polarity of the supply voltage must be reversed, making a control circuit a lot more involved and complex.įigure 1. Some installers like to use one color for “on-air” indications and the other color for “Recording,” or “phone ringing,” or some other useful annunciation. What’s more is the fact that newer mic arms with built in tally lights now support dual colors, typically red and white. Some have even gone with quick and dirty “transistor directly in the euroblock” method of wiring. Many engineers out there have resorted to creating some sort of perf-board circuit with transistors or relays to control these tally lights. This is more current than a GPIO port on an Axia device is rated to handle. These LEDs at 12 volts typically draw 30-40 milliamps of current, and possibly more at 24 volts. Most of these types of mic arms have a ring of multiple LEDS that are used to indicate which mic is live on the air. The first is to make it obvious which camera is live for the on-camera talent and the second is to keep the camera operator aware of his camera's status.The NotaBotYet Tally Helper 100 was designed to control tally lights on popular mic arms such as Yellowtec Mika products and others.

TALLY LIGHT PORTABLE
So it’s a must have, but how do you do it? Most studios use portable cameras as their studio cameras and they have no true built-in tally light.
TALLY LIGHT PROFESSIONAL
Ever been in a professional studio that did not have tally lights for all of the cameras? If the professionals think it’s important, it should be high on the list of “must haves” for all studios. Tally lights are important tools in a broadcast studio. A tally light system is usually an afterthought for the smaller, non-network broadcast studio because there is no cost-effective or workable solution. How does your talent know which camera to look at when doing a live production in your studio? A very common problem is that there is no tally light system for the cameras. So you have this fancy Tricaster or video switcher with all the bells and whistles, except one very important “bell".
