4.8.3 Clear ZeroThis will clear the zero offset and return to the calibrated absolute output.4.8.4 3 Pt. AdjustThe 3 point adjust makes a slight adjustment to an existing calibration. It allows for correction ofinstallation or slight loading errors in gain and offset. For this calibration, the sensor must bepositioned at MIN, MID, and MAX with data taken at each point. This adjustment does notoptimize the output further; it simply corrects scale, offset, and small linearity errors.Temperature coefficients are not changed. It will remove any offset from zeroing the sensoroutput. This option is used when more accuracy, but not a full calibration is required.www.kaman<strong>sensors</strong>.com PART NO: 860525-001Last Revised 9/16/2013- 12 -
PART 5 - ETHERNET OUTPUTThe digiVIT has an Ethernet output that communicates via a UDP/IP protocol. To protect thepacket it is required that any command is preceded by a sequence number and has a checksumat the end. It has a fixed IP address (which can be changed) and utilizes fixed ports (these canalso be changed) for sending and receiving data.5.1 Default IP Address & PortsDefault IP Address: 192.168.0.145Default UDP Writer Port: 55555Default UDP Reader Port: 555565.2 UDP PacketThe packet sent over the UDP port must be preceded by a sequence number and followed by achecksum. This is necessary because UDP does not guarantee arrival of the packet to thehost. The format of the packet is:$s#CCWhere the $ is the command preface and s is a sequence character from ASCII 'a' to 'z'. Whenthe digiVIT receives a command, it will respond with the same sequence number sent as thefirst character of the string. It is up to the host to determine if the packet arrived in sequenceand to take any action.The checksum is the last two characters and is preceded by the # sign indicating the checksumcharacters follow as the payload length is variable. It is the inverted 8 bit sum of the ASCIIvalues in the payload including the sequence number.www.kaman<strong>sensors</strong>.com PART NO: 860525-001Last Revised 9/16/2013- 13 -
