Using the Input/Output Panel
To access the input/output (I/O) ports, remove the cable cover at the bottom of the unit. A security screw is included and may be used to secure the cable cover to the touchcomputer. Below are the I/O descriptions by model:
B1 and B3 models
B2 models
Note: The DB9 Serial (COM) ports are defaulted (from left to right) COM3 and COM4
Note: As a safety precaution, always leave the cable cover door attached when the system is powered on.
