Manual revision 006 Section 4: Deploying and Operating SBE 19plus V2 SBE 19plus V2

RS-232 Sensor Setup Commands (continued)

Setup for WET Labs Sensor

(single, dual, or triple ECO Sensor; WETStar, or C-Star):

• 19plus V2 must be set to 19200 baud (BaudRate=19200) if interfacing

with a WET Labs RS-232 sensor.

• If in Moored mode: 19plus V2 DelayBeforeSampling= must be > 2 sec if

using a WET Labs RS-232 sensor. If WetLabs=Y and

DelayBeforeSampling < 2 sec, 19plus V2 automatically sets

DelayBeforeSampling=2.

Note that the SBE 19plus V2 stores and outputs 6 bytes of WET Labs RS-232

data for each sample, with 2 bytes for each channel. If integrating an ECO

Triplet, each sensor of the Triplet uses 2 bytes (for a total of 6 bytes). If

integrating a dual ECO sensor (such as the FLNTU), the first 4 bytes contain

the sensor data; the remaining 2 bytes are 0’s. For single WET Labs RS-232

sensors, the first 2 bytes contain the sensor data; the remaining 4 bytes are 0’s.

WetLabs=x x=Y: Enable WET Labs RS-232 sensor.

x=N: Do not enable WET Labs RS-232

sensor.

Note:

In Moored mode, the 19plus V2

sample interval (SampleInterval=)

must be greater than or equal to the

sum of the times required to sample.

Total time is affected by the following:

- Minimum time required for 19plus V2

to take a sample (≈ 2.5 sec).

- Time required for 19plus V2 to take

and average NCycles= samples;

samples are taken 0.25 sec apart.

- Delay after providing power to

external sensors before sampling

(DelayBeforeSampling=); minimum

DelayBeforeSampling= is 2 sec if

using a WET Labs RS-232 sensor.

- Time required to run pump before

sampling (0.5 sec if

MooredPumpMode=1).
