February 2020 – TD 266 OPERATING MANUAL – ZPulse® DCS 4420/4830/4520/4930 Page 131
Specific Changes:
1. Input command line termination is changed from line feed (LF) with optional carriage return to line feed and
mandatory carriage return (LF+CR).
2. ‘Do Stop’ and ‘Do Start’ command changed to ‘Stop’ and ‘Start’
3. All units in output string changed from ‘(‘ and ‘)’ type parenthesis to ‘[‘ and ‘]’ type, example [hPa].
4. The Sleep indicator (‘%’) and the Wakeup indicator (‘#’) is replaced by a Communication Sleep (‘%’) indicator and
a Communication Ready (‘!’) indicator. A property called ‘Enable Comm Indicator’ can be used for
enabling/disabling of these characters.
5. Polled mode is no longer enabled by setting the interval to zero (Set Interval(0) is now illegal). A property called
Enable Polled Mode is now used for controlling polled/non-polled mode.
6. The ‘Output’ property is substituted by a ‘Mode’ property for changing the operation mode, for example; ‘Set
Mode(Smart Sensor Terminal)’. Specific properties control the formatting of the output string, for example ‘Set
Enable Text(no)’.
7. The startup notification (at power up) is changed from ‘Mode <Mode name>’ to the following format:
‘StartupInfo <Product No.> <Serial no.> Mode <Protocol Name> Version <Version No.> Config Version
<Version No.>’, for example; ‘StartupInfo 4330 83 Mode AADI Smart Sensor Terminal Protocol RS-232
Protocol Version 3 Config Version 6’
8. The startup notification will be switched off when the ‘Enable Text’ property is set to ‘no’.
9. A ‘*’ will precede the parameter name if an error status related to the specific parameter occur. This applies for
example to the tide parameter of the Wave an Tide Sensor before the sample base is complete : ‘*Tide
Pressure[kPa] 0.000000E+00’
