Description
The ICT AZB-21 Anti-Zapper Board (12VDC with Fanout Cable) is designed to protect ICT systems from electromagnetic interference and zapper-related disruptions while maintaining stable communication between connected components.
Operating on 12V DC power, this board converts RS232 (UART) communication into a pulse interface, making it suitable for vending and amusement systems that require pulse protocol integration. The included fanout cable allows flexible wiring and easier installation between system components.
This anti-zapper board is installed between the system controller (VMC) and compatible ICT devices, helping ensure reliable signal transmission and protecting sensitive electronics in standard operating environments.
