KC868-A6 Flow Control

[Edomicianoa]

Prezada Equipe de Suporte Técnico da KinCony,
Estou usando a placa de automação residencial inteligente KC868-A6 V1 4SP .
Preciso saber se é possível usar o controle de fluxo de hardware RTS/CTS (Request To Send / Clear To Send) nas portas seriais RS232 e/ou RS485 integradas .

• Em caso afirmativo: Poderia especificar quais pinos da placa estão atribuídos aos sinais RTS e CTS para as interfaces RS232 e/ou RS485?
  
• Caso a resposta seja NÃO: Você poderia recomendar um modelo alternativo de placa KinCony que suporte o controle de fluxo de hardware RTS/CTS por meio de sua interface RS232?
  

Agradecemos imensamente sua ajuda para esclarecer as capacidades de hardware da placa KC868-A6.
Muito obrigado,

sorry, we have not used RTS/CTS pins, we have use MS2548 for RS485 circuit.

Thank you for your quick response. I appreciate the information about the MS2548 chip used in the RS485 circuit.

I understand that the MS2548 likely provides Automatic Direction Control for the RS485 communication, which means a separate RTS/CTS signal is not needed for the RS485 interface.

Could you please confirm the following points?

RS485 Confirmation: Is it correct that the RS485 port on the KC868-A6 V1 4SP does not require an external RTS signal because its direction switching is managed automatically by the MS2548 chip?

RS232 Status: Can you confirm if the RS232 port on the KC868-A6 V1 4SP has the RTS and CTS pins available for hardware flow control? (My initial question did not receive a specific answer for RS232).

This confirmation is important for my device setup. Thank you once again for your assistance.

Best regards,

RS485 Confirmation: Is it correct that the RS485 port on the KC868-A6 V1 4SP does not require an external RTS signal because its direction switching is managed automatically by the MS2548 chip? --- Yes, you not need to use RTS for direction.

RS232 Status: Can you confirm if the RS232 port on the KC868-A6 V1 4SP has the RTS and CTS pins available for hardware flow control? not used RTS and CTS pin in DB9 interface, only RXD, TXD, GND 3 pins used.
