6000 Series user’s manual EZ I/O
can be individually programmed as 5V input or 5V output. Each line
can sink or source 15 mA.
6020 — Pulling the I/O lines high or low
Jumper block W3 pulls ports A, B, and C of EZ I/O 1 high or low.
Jumper block W4 pulls ports A, B, and C of EZ I/O 2 high or low.
Note For the location of W3 and W4, refer to the component diagram in the
6020 technical data appendix.
Table 6-3 6020 pull-down/pull-up EZ I/O configuration

W3[2-4] All lines in Port A are pulled to Gnd through 10K Ohm
W3[4-6]* All lines in Port A are pulled to +5V through 10K Ohm
W3[7-9] All lines in Port B are pulled to Gnd through 10K Ohm
W3[7-8]* All lines in Port B are pulled to +5V through 10K Ohm
W3[1-3] All lines in Port C are pulled to Gnd through 10K Ohm
W3[3-5]* All lines in Port C are pulled to +5V through 10K Ohm
* = default, pins jumpered
Table 6-4 6020 pull-up/pull-down EZ I/O 2 configuration
Configuration Description
W4[2-4] All lines in Port A are pulled to Gnd through 10K Ohm
W4[4-6]* All lines in Port A are pulled to +5V through 10K Ohm
W4[7-9] All lines in Port B are pulled to Gnd through 10K Ohm
W4[7-8]* All lines in Port B are pulled to +5V through 10K Ohm
W4[1-3] All lines in Port C are pulled to Gnd through 10K Ohm
W4[3-5]* All lines in Port C are pulled to +5V through 10K Ohm
* = default, pins jumpered
6020 — Organization of ports
The two EZ I/O digital ports have 24 I/O lines connected to J1 and 24
lines connected to J7. Each of the 24 lines are configured into three
groups consisting of 8 lines each. Any of the lines at ports A, B, or C can
be configured individually as inputs or outputs. Immediately after
reset, each I/O line becomes an input.
