How to Connect / Disconnect a Sensor Module
To connect a sensor module to the 90XL display module:
1. Turn the display module ON by using the left-most key, labeled with the symbol
2. The sensor module may be connected to any vacant port.
3. Plug the connector into the port until a slight click is felt.
There is a slight pause while the sensor module establishes communication with the
display module. The 90XL will then display the reading on the channel that matches the
sensor module connector.
To disconnect a sensor module from the 90XL Display Module:
Using your fingers, gently pull straight away from the socket to remove the connector
from the port. Do not turn or rotate the cable end. Cover the port with the protective cap
to prevent dirt, dust or fluids from entering the connector.
