  • Page 24 COMMUNICATIONS & GETTING STARTED C.1.1 Serial interface Communicating with the DAS 72.1 digitizer is carried out via the RS422/RS485 port. The data format is the familiar 8/N/1 structure (8 data bits, no parity, 1 stop bit). Available baud rates via the RS422/RS485 port are as follows: 9.600, 19.200, 38.400, 57.600 or 115.200 baud.
  • Page 25 C.1.3 Setup baud rate / device address Baud rate Factory default: 9600 baud Address settings It is possible to set the network address of the device using the AD command. (Address range between 0 and 255). Setting the device address to 0 will set the continuously active mode, where the device becomes permanently active, and will listen and respond to any command on the bus, without the need for an OP xxx command.

The zero set during calibration remains the ‘true zero’ but new ‘current zero’ can be set using the SZ command. If the SZ command is issued and accepted then all weight values will then be based on the new ‘current zero’.
  • Page 41 Set Tare This command will activate the net weighing function by storing the current weight value as a tare.

  • Page 54 CALIBRATION PROCEDURE. The calibration interface features a “TRACEABLE ACCESS CODE” (TAC), as is required for use in “Approved” applications (see section 7, “USE IN APPROVED APPLICATIONS” for more details). This feature also ensures that access to the calibration functions is protected from inadvertent or unauthorised change. The following parameters are considered as CALIBRATION commands: Calibration Enable - returns the current TAC value.
  • Page 55 USE IN “APPROVED” APPLICATIONS (only as information) The term “approved” applies whenever the weighing application is intended to be used for “legal-for-trade” weighing - that is, money will change hands according to the weight result. Such applications are bound by the legal metrology regulations of the relevant governments around the World, but most countries will comply with either the relevant EN’s (Euro Norms) or the relevant OIML (Organisation Internationale de Metrologie Legale) recommendations.
