Test All
Sets all GPI Outputs to the inactive state (logic high or 5 volts) and
sets each GPI Outputs to the active state (logic low or 0 volts) one
by one in succession as shown below.
1 → 2 → 3 … 22 → 23 → 24 → 1 → 2 → 3 …
Clicking the button again will stop the sequence.
Query GPI
An eBOX sends a GPI Status message in any of the following
cases:
• whenever any of its GPI Inputs change states,
• periodically every 5 seconds or,
• when a GPI Query command is received.
Clicking the Query GPI button sends a GPI Query command to the
connected eBOX causing the eBOX to immediately return the
states of its GPI Inputs. Clicking the Query GPI button is a good
way to verify that the eBOX GPI Tester Utility is still connected to
the eBOX under test.
Note: The eBOX GPI Utility does not use the Password protection
feature of the eBOX so that feature will have to be disabled by setting
DIP switch 6 to the ‘ON’ position.
