Bosch PT-400 Push-To-Talk Switch Kit
Overview
The Bosch PT-400 is a double-pole, double-throw (DPDT) in-line push-to-talk switch designed for integration into communication systems requiring manual audio transmission control. Its locking feature ensures the transmit function remains engaged until intentionally released, simplifying hands-free operation in specific scenarios like long-duration broadcasts or system diagnostics. This accessory is suitable for deployments where a reliable, physical interface is needed to trigger audio transmission on compatible Bosch communication devices.
Compatibility
The PT-400 is designed to interface with Bosch communication systems that support external push-to-talk controls. While specific model compatibility is not detailed in the provided evidence, it is intended for use with systems that accept a dry contact closure for transmit activation. The Modbus RTU protocol support suggests potential integration with broader control systems, provided they can interpret the switch's state changes.
Installation Notes
This switch requires a power supply voltage between +9 and +28 VDC. It supports Modbus RTU communication with configurable baud rates (2400, 9600, 19200, 38400) and parity settings (none, even, odd), along with 1 or 2 stop bits. Proper wiring of the DPDT contacts is essential for correct operation, ensuring the switch correctly closes the transmit circuit when pressed and maintains that state when locked.
