Coin Acceptor Module 261 Pulses Data Record RS232 Interface 9600 Baud Rate PBC Coin Mechanism Board for Coin DispenserItem Type: Coin Acceptor ModuleMaterial: PBCBaud Rate: 9600Operating Mode: Half DuplexCommunication Character Format: 1 start bit, 1 stop bit, 8 data bits (Bits 0 = sent first (LSB)Lockout Timer:Within a certain period of time, if the WF-700B does not receive a response to a request, it will lock the coin dispenser as set by the hardware dipswitch. The lockout time can be set by the dipswitch to 1 second, 10 seconds, 20 seconds or no lockout.Data Stack, Parallel Mode: WF-700B has a serial data stack, which is composed of FIFO way. In case of communication loss with the host, coin data will be temporarily stored in the WF-700B data stack. When the data stack is full, WF-700B will automatically disable the coin acceptor to prevent data loss.WF-700B's serial data stack is a coin data pulse counter, capable of recording up to 261 pulse data. Each pulse input will generate a single data.1. The WF-700B interface board connects the coin acceptor and PC host's serial communication port through the built in RS232 interface module. With WF-700B, terminal development users can easily develop coin control devices without having to consider the control performance and interface of various coin acceptors. WF-700B is an upgraded version of WF-700, and can easily set relevant working parameters via a four digit DIP switch.2. WF-700B works as a slave device in the system, able to respond to host device requests at any time.3. WF-700B has a 'Lockout' timer function, which can disable the coin acceptor in case the host does not interact with the working frequency, or encounters busy or other unexpected failures, until the host resumes work.
