4.1.4 Starflow QSD - SET/RESET Option Settings (aX5)
To alter the operation of QSD, there are 32 option settings numbered 0 to 31. These affect QSD's
performance so must be changed "wisely". The aX5 eXtended command is used and several options
adjustments (set and/or reset) can be made using a single aX5 command. A SET option is a
<+value> and RESET a <-value>. The <value> is the option number 0..31. Undefined options MUST
NOT be changed.
Option No. SET Meaning
<value> < + value>
04 Enable Pressure Depth
05 Zero P.Depth on Fail
06 Enable Barometric Ref
07 Show –ve P.Depth
08 Enable Electrical Conductivity (EC) Disable Electrical Conductivity (EC=0)
16 Enable Depth Measurement
17 Depth = 0 if < Min Operating Level
18 Enable Depth Drive 1
19 Enable Depth Drive 2
20 Enable Depth Drive 3
21 Enable Depth Drive 4
22 Use MEDIAN value for Depth
24 Enable CW Velocity Measurement
25 CW Velocity = 0 if < MIN RSSI
26 Enable -ve CW Velocity
27 Enable SOS Temp Corr.
31 Velocity = 0 if > MAX SPREAD

Notes: ** The Sensor address is an ASCII value so DOES NOT use a ± sign.
*** Only SET Options are displayed. Change order is not important.
**** Except for aX5, the order of changed parameters IS important. You MUST
re-enter all parameters occurring prior to the parameter you wish to change.
