Section 3: Power and Communications Test
26
3. Seaterm232 will try to automatically connect to the 19plus V2. As it
connects, it sends GetHD and displays the response, which provides
factory-set data such as instrument type, serial number, and firmware
version. Seaterm232 also fills the Send Commands window with
the correct list of commands for your 19plus V2.
If there is no communication:
A. In the Communications menu, select Configure. The Serial Port
Configuration dialog box appears. Select the Comm port and baud
rate for communication, and click OK.
B. In the Communications menu, select Connect (if Connect is grayed
out, select Disconnect and reconnect).
C. If there is still no communication, check cabling between the
computer and 19plus V2, and try to connect again.
D. If there is still no communication, repeat Step A with a different baud
rate and/or comm port, and try to connect again. Note that the
factory-set baud rate is documented on the Configuration Sheet.
After Seaterm232 displays the GetHD response, it provides an S> prompt
to indicate it is ready for the next command.
4. Display 19plus V2 status information by typing DS and pressing the Enter
key. The display looks like this:
SeacatPlus V 2.1 SERIAL NO. 4000 20 Oct 2008 14:02:13
vbatt = 10.1, vlith = 8.9, ioper = 61.9 ma, ipump = 20.8 ma,
iext01 = 76.2 ma
status = not logging
number of scans to average = 1
samples = 10, free = 4386532, casts = 1
mode = profile, minimum cond freq = 3000, pump delay = 60 sec
autorun = no, ignore magnetic switch = no
battery type = alkaline, battery cutoff = 7.5 volts
pressure sensor = strain gauge, range = 1000.0
SBE 38 = no, Gas Tension Device = no
Ext Volt 0 = yes, Ext Volt 1 = yes
Ext Volt 2 = no, Ext Volt 3 = no
Ext Volt 4 = no, Ext Volt 5 = no
echo characters = yes
output format = converted decimal
output salinity = no, output sound velocity = no
5. Command the 19plus V2 to take a sample by typing TS and pressing the
Enter key. The display looks like this (if in Profiling mode, with
converted decimal output format, no output salinity or sound velocity, and
auxiliary voltage sensors on channels 0 and 1):
23.7658, 0.00019, 0.062, 0.5632, 2.3748
where 23.7658 = temperature in degrees Celsius
0.00019 = conductivity in S/m
0.062 = pressure in db
0.5632 = voltage for auxiliary sensor channel 0
2.3748 = voltage for auxiliary sensor channel 1
These numbers should be reasonable; e.g., room temperature, zero
conductivity, barometric pressure (gauge pressure).
6. Command the 19plus V2 to go to sleep (quiescent state) by typing QS and
pressing the Enter key.
The 19plus V2 is ready for programming and deployment.
Notes:
• The 19plus V2 automatically enters
quiescent (sleep) state after
2 minutes without receiving a
command. This timeout algorithm is
designed to conserve battery energy
if the user does not send QS to
put the 19plus V2 to sleep.
If the system does not appear to
respond, click Connect in the
Communications menu to
reestablish communications.
• Sending the status command
causes the pump to turn on for a
moment, so that the 19plus V2 can
measure and output the pump
current. Because the pump is
designed to be water lubricated, you
may hear a noise when the impeller
spins in air. Running the pump dry
for short periods (for example, when
sending the status command) will
not harm the pump.
Note:
If OutputExecutedTag=Y, the 19plus
V2 does not provide an S> prompt
after the <Executed/> tag at the
end of a command response.
Note:
Seaterm232’s baud rate must be the
same as the 19plus V2 baud rate (set
with BaudRate=). Baud is factory-set
to 9600, but can be changed by the
user (see Command Descriptions in
Section 4: Deploying and
Operating SBE 19plus V2). Other
communication parameters –
8 data bits, 1 stop bit, and no parity –
cannot be changed.
