I/O X-Card RS-232 Port
Pins 1, 2, 5 and 6 plus the ground on pin 10 provide 4-wire RS-232
communication. It also supports features like AT, TCP PAD and UDP PAD.
Note: There is no connection for RI, DCD, DTR or DSR.
I/O X-Card Digital I/O Input Pins
Pins 3, 4, 11 and 12 are programmed in ALEOS to monitor inputs, respond to
certain types of events or trigger a digital output. They behave exactly like the
Digital I/O (pin 4) on the power connector as described in Power Connector
Description on page 24.
Note: Pin 4 on the power connector is called Digital Input 1 in the ACEmanager screen.
Pins 3, 4, 11 and 12 (Digital inputs 2 to 5) have a voltage of 2.8VDC when it is set
to high in ALEOS. A voltage on the pins of:
•2.2VDC to 30VDC=logic 1
• -0.5VDC to 1.3VDC=logic 0
I/O X-Card Analog Voltage Input Pins
Pins 7, 8, 14 and 15 are analog voltage sensing pins programed in ALEOS to look
for specific events. The pins have a maximum rating of 30V, 200uA.
These pins detect inputs of 0–30VDC across the pins to ground. When used with
a converter to transform values into voltages, the pins can monitor measurements
like temperatures, pressures or the volume of liquid in a container. ALEOS can
transform these voltages into meaningful values. In ALEOS, events reporting tells
the device to perform an action when a specified voltage is detected.
