Contec IPC Series User Manual page 87

Purpose: Make 4 input-output pairs to cross-verify the GPIO functions.
Procedure:
1. Use 4 jumpers or wires to connect the following pin cobination.
1 - 6, 2 - 3, 4 - 5, 7- 8
===========================
| 1 2 -- 3 4 -- 5 |
| \
\ 6 7 -- 8 9 /
========================
2. Set PINs 1, 2, 4, 7 as Output; PINs 3, 5, 6, 8 as input.
Case A: Set all Output level to Low; It is expected that other input PINs should be pulled low,
and eventually all PINs levels should be 0. And its comparsion should return errorlevel 0.
BXS2000_GPIO -io=00101101 -hl=00101101
BXS2000_GPIO -cp=00000000
result:
PIN 1234-5678
==== ====
In(1)/Out(0): 0010 1101
Level
Compare
Level comparison is identical.
Case B: Set all Output level to High; It is expected that other input PINs should be pulled high,
and eventually all PINs levels should be 1. And its comparsion should return errorlevel 0.
BXS2000_GPIO -io=00101101 -hl=11010010
BXS2000_GPIO -cp=11111111
result:
