Setting up with a terminal program
We recommend lightly abrading the transducer prior to the first deployment
Connecting
The sensor is terminated using a MCBH6M connector with the following pin-out:
| Pin | Function |
|---|---|
| 1 | Ground |
| 2 | Power |
| 3 | RS232 Sensor Receive |
| 4 | RS232 Sensor Transmit |
| 5 | RS485 B - Inverting (for sensors with a serial number > 3000028) |
| 6 | RS485 A - Non-Inverting (for sensors with a serial number > 3000028) |
Because of the potential for different vendors to use different signal definitions, if you connect our sensors' A/B wiring to your communication device and communication does not work, try reversing the signals.
Communicating
- Connect sensor to power and control system
- Select correct com port
- Select speed = 57600, Data = 8bit, Parity = none, Stop bits = 1, flow control = none
- All lines should be terminated with a CR
Once set-up is complete, turn on the sensor. The sensor will beep once and the following will be displayed:

Do not run the sensors in pH buffer solutions. They are for use in seawater - freshwater.
Whenever the sensor is to be powered off, the sensor must be shutdown properly, simply by typing 'shutdown', as shown here:

It is now safe to power down the system
If you are using a parsing script on a connected microprocessor to access the menu functions and change the parameters in the sensor you will need to write a script that issues commands mimicking accessing the Primary Menu.
