Step 6—I/O Configuration
You can use Pin 4 on the LX40 power connector for I/O configuration.
Figure 2-11: I/O Pin-out for the LX40 Power Connector
You can use the I/O pin as:
· Pulse counter
(See
Table 2-3 on page 25 and Figure 2-12 on page 25.)
· Digital input
(See
Table 2-3 on page 25 and Figure 2-13 on page 26.)
· High side pull-up/dry contact switch input
(See
Table 2-5 on page 27 and Figure 2-14 on page 27.)
· Analog input
(See
Table 2-6 on page 28 and Figure 2-15 on page 28.)
· Low side current sink
(See
Table 2-7 on page 29 and Figure 2-17 on page 29.)
· Digital outputs/open drain
(See
Table 2-8 on page 30 and Figure 2-18 on page 30.)
For more information, refer to the ALEOS Software Configuration User Guide.
Note: You can configure the GPIO Pin 4 in ACEmanager or ALMS to trigger standby mode, to sink
current, or to pull up the voltage. If you are using the I/O line to trigger standby mode, you cannot
configure it to sink current or pull up the voltage. Likewise, if you are using the I/O line to either sink
current or pull up the voltage, you cannot use it to trigger standby mode.
Note: During bootup, the I/O settings remain in their default state: the internal pull-up resistor is
disabled, and output current sink switch is open. After bootup, any custom I/O settings are applied.
This may take approximately 30 seconds after the gateway is restarted or powered on.
