RS232 REMOTE CONTROL

Connection with standard RS232 protocol: 9600kbps, 1 stop bit, No handsk

Command PC -> Device

ASCII Chr “9” = 57 = START Acquisition Data

ASCII Chr “8” = 56 = STOP Acquisition Data

ASCII Chr “5” = 53 = Autozero Gauges

ASCII Chr “6” = 54 = Autozero Accelerometers

ASCII Chr “0” = 48 = Set DAC Straight Gauge = 2.5V

ASCII Chr “1” = 49 = Set DAC Curve Gauge = 2.5V

ASCII Chr “2” = 50 = Set DAC X Acc = 2.5V

ASCII Chr “3” = 51 = Set DAC Y Acc = 2.5V

Device -> Command PC

When received START command, device send acquired value for Gauges and Accelerometers:

Each value is four digit in hexadecimal representation (the first oneis ever equal to zero), ranging form 0x0000 = 0V to 0X03FF = 5V .

The values are separated by tabulation (9 in ASCII).Each acquisition is separated by a carriage return (13, 10 in ASCII)

The order of rows is:Straight gauge value – TAB – Curve gauge value – TAB – Acc X value – TAB – Acc Y value – CR

The acquisition can be done configuring in suitable way the the Windows HyperTerminal
