Lo que encontró el hilo
- La configuración de pins para conectores XLR de 3 pines de 24 voltios difiere entre regiones geográficas y fabricantes, sin un estándar universal único en toda la industria.
- European equipment typically uses pin 1 as negative and pin 2 as positive on 24-volt 3-pin XLR connectors.
- United States equipment often uses pin 1 as positive and pin 2 as negative on 24-volt 3-pin XLR connectors, opposite to the European convention.
- A 3-pin male to female XLR adapter cable with pins 1 and 2 swapped can be used to convert between different regional wiring standards.
- Battery voltage readings above the nominal 24 volts, such as 33 volts immediately after charging, are normal and do not damage cameras, as batteries quickly discharge under load to their operating range.
- Newly charged 14.4-volt batteries commonly read 16 or more volts before settling to lower voltages under use.
Depende de
- Different manufacturers use different standards even within the same geographic region.
- The specific pinout can vary between rental houses and equipment suppliers.
- Testing with a multimeter is the only reliable way to determine the actual configuration of any specific equipment before connecting cameras.
