IMPORTANT NOTES!
–
Wire colors are included to identify the pins used for this
connection. Colors shown do not represent any wiring standard.
–
When wiring, DO NOT connect any wires within the cable that are
not required for communications.
–
Pins 7 & 8 are only required for CTS/RTS handshaking.
–
CTS/RTS handshaking is supported for flow control based on the
profile used in the Blueprint configuration.
–
RS-422/485 is not supported
–
Refer to the
RS-232 Conversion to DB9 and RS-422/485 Pin-out

GPIO - General Purpose Input/Output
–
GPIO’s configured
as an output can
be used to trigger
an action within
the system such as
switching a device.
–
GPIO configured
as an input can
detect a state
change and trigger
a workflow.

I/O PD
Pin 2: GPIO 1
Pin 3: PD (Pulldown)
–
GPIO pins configured as an input are pulled high to (+12V) during
the boot process. To force the GPIO signal low during a boot-up,
connect the PD pin to the GPIO pin. This forces the GPIO output to
(< 0.8V) during the processor boot times.
IR Wiring (Infrared)
–
Ensure that all IR
emitters are within 15
feet (4.6 meters) from
the controller’s location.
–
Use of 3rd party
flashing IR emitters
with Talk Back is not
recommended. These
types of emitters can
draw voltage away from
the IR signal that can
degrade IR performance.

GPIO Input
- When configured as an input, the
processor will look for a low (<0.8V DC) or a high
(>2.4V DC) state. Minimum 0V DC / Maximum
12V DC.
GPIO Output
- When configured as an output,
the port provides a binary output of 0-12V DC
150mA max.

5V DC
5V DC 3A - Connect included wall wart power
supply between the 5V DC connection and a 115-
240V AC surge protected outlet.
