1.7.4 User Maintenance
This group contains sensor settings that normally are not altered by the user. To access most of these properties you
need to send passkey(1000) or with Real-Time Collector use password: 1000. These properties are used to configure
serial port settings, communication to and from sensor. If you got a wave license key you may also enable wave
functionality, you may enter temperature coefficients if Temperature sensor is included, set limits for discarding ping if
sensor tilt exceeds the limits and property to set the distance from pressure sensor port to centre of transducer
elements.

Description
String 31
User text for describing node, placement etc. Default Doppler Current
Sensor #xxx. Where xxx is the serial number.
UM
No /
Low
Owner String 31 User setting for owner information, company name etc.
Interface String 31 Factory use only, RS232 for standard version, RS422 for R-version
Baudrate ENUM 1
RS232 baudrate: 4800, 9600, 57600, or 115200. Default baudrate is
9600. The baudrate affects the minimum available Interval setting.

Flow Control ENUM 1
RS232/RS422 flow control: ‘None’ or ‘Xon/Xoff’. The Xon/Xoff’
characters are also sent for each Doppler ping measurement. To
remove the “disturbance” on the receiver, select None. Be aware that
this may also lead to missing characters when sending commands to
the sensor.
Enable Comm
Indicator
ENUM 1
Enable communication sleep (’%’) and communication ready (‘!’)
indicators. After the last communication with the sensor, it normally
outputs a ‘%’ when the Comm Timeout time is over. When a character
is sent to the sensor, it outputs a ‘!’ to indicate that it is ready to
communicate.
Comm
TimeOut
BOOL 1
Time communication is active (Always On, 10 s, 20 s, 30 s, 1min, 2
min, 5 min, 10 min). A short time means that the sensor is going to
sleep faster after a communication input.
Enable Old
Wakeup
Character
BOOL 1
Enables old wakeup character `#`instead of `!`. Use Enable Comm
Indicator to switch on and off these characters.
Enable 4100
Output
BOOL 1
Enables the old 4100 output for use in old system where the sensor is
replacing an older version. Output structure is set by select mode
using Select 4100 Output Mode
