Setting up with a terminal program

Connecting​

The sensor is terminated using a MCBH6M connector with the following pin-out:

PinFunction
1Ground
2Power
3RS232 Sensor Receive
4RS232 Sensor Transmit
5RS485 A (for sensors with a serial number > 3000028)
6RS485 B (for sensors with a serial number > 3000028)

MCBH6M

Communicating​

  1. Connect sensor to power and control system
  2. Select correct com port
  3. Select speed = 57600, Data = 8bit, Parity = none, Stop bits = 1, flow control = none
  4. 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:

tip

If you would like the sensor to record the time please set the internal clock

caution

Do not run the sensors in pH buffer solutions. They are for use in seawater - freshwater.

caution

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.
