EZ I/O 6000 Series user’s manual
WARNING!
Apply power to the PC Microcontroller before applying an
input voltage to the digital I/O lines. This prevents excessive
currents from flowing and damaging input devices.
The following chart specifies PC Microcontroller cards with EZ I/O
capability.

EZ I/O is located at the J1 connector for the 6020, 6040, and 6050. An
additional EZ I/O port is located at J7 on the 6020. Refer to the prod-
uct-specific appendix for its associated jumper setting. Each EZ I/O
connector is configured below:

*Port B can only be configured as output on the 6050. The output level is inverted
from input. This is due to the inverted-output, high-current driver used on the
6050. Consider these factors when using and programming this port.

Model 6020
Each EZ I/O port has 24 I/O lines available, which makes a total of 48
lines. The 24 I/O lines are divided into three groups of 8 with 10K
resistors that can be connected to ground or +5V. Each of the 48 lines
