2.4
Because all of signals were not isolated, the ground (pin1 and pin8) of GPIO board and signal
ground of external device need to connect directly, it should avoid different GND pin
connecting GPIO board and make this board fail.
2.5
Suggest the length of connect cable between GPIO interface and external device should less
than 15 feet to avoid the noise and error happen.

Description of input/output signals
3.1
There 4 input pins for application.
(1)
Pin 3
Start Print:
a.
This signal active make the printer start to do the print job, it is active low.
b.
When print job was finished, the output pin of End Print will send a pause (500ms),
and the external device should disable the Start Print signal.
c.
The output pin of Data Ready will follow the “Start Print” signal to external device.
d.
Timing chart is as Figure 4.
Figure 4

Pin 4
Feed:
a.
The signal is make the printer feed action; the distance is determining the internal
setting.
b.
When during feed processing, the output pin of Data Ready will active and disable till
the end of feed.
c.
The timing chart is as Figure 5
