The signal jacks and connectors available on the I/O Jack and PoE PCB are listed in
Table 20
below.
Note that connectors J33 and J34 are only present starting with the 30-0091-12 I/O board, and older
versions do not have these connectors.
Connector Type
Function
J5
1.25mm header
RS485 I/F. Pin 1 is “A”, pin 2 is
“B”.
J8
RJ-45 jack
Gigabit Ethernet
J14
USB 2.0 Type A
USB Host Interface
J17
DC Jack, 5.5/2.0mm Threaded jack for +12V power entry
J21
RCA jack
Composite video output
J29
3.5mm stereo jack
Microphone input. Tip=MIC_N, Ring=MIC_P, Ring=GND
J32
2.5mm stereo jack
Serial port interface, RS232 level. Tip=RX, Ring=TX, Sleeve=GND
J33
1.25mm header
(unpopulated)
Duplicate RS485 connector for Z3 internal use. This connector
uses the exact same signals as J5 and
does not
offer a second
RS485 interface. Unpopulated from the factory.
J34
1.25mm header
UART4 interface. Pin 1=TX, Pin 2=RX, Pin 3=GND, Pin 4=3.3V

In addition, the PCB contains a bi-color Green/Red LED, and a tact switch.
The LED, D29, is controlled by GPIO0_1 (red) and GPIO0_2 (green). Setting each one of these GPIO
controls to logic 1 will turn on the corresponding LED color.
The tact switch can drives the GPIO0_3 pin, ball W17 of the CPU. This signal can be used by the
software to implement special functionality such as a 1-key recovery mechanism or other user-
defined functions.
