MicroBuffer - specifications

data collection

Automatic Configuration

  • Detects pin 2 or 3 for received data
  • Obtains correct baud rate to match sending device
  • Works out correct protocol from the data stream
  • Maintains correct baud and protocol even if datasource changes

Choice of Format

  • Binary mode captures full 8 bit data
  • ASCII only mode stores 7 bit data

Circular/Linear Memory

  • If PC is not connected or ready, new data will overwrite old data when the memory is full - keeping the newest 1Mbyte of data
  • When PC is ready, the memory remains in standard 'linear' mode

data delivery

Hardware Flow Mode

  • Sends stored data when both CTS and DTR remain asserted

Hardware/Software Flow Mode

  • Send data when both CTS and DTR remain asserted, and the XON character is sent to the MicroBuffer. Data flow can be paused by sending the XOFF character, or unasserting the handshake lines.

applications

Provide Resilience

  • Buffering the data allows the connected computer to be rebooted or upgraded and minimise data loss

'Post and Forget' Distribution

  • Using the MicroBuffer with your application will allow simple installation for your customer. They can connect the MicroBuffer with standard cables and not worry about DCE/DTE, baud rates, or protocols.
