2. Device interface

2.1 Front panel

（1）PWR: after the power supply is switched on, light indicates power status.

（2）SYS: the system will run normally if the indicator is flickering and the indicator will be off for a

long time during Starting.

（3）USB：the system supports USB recording.

2.2 Rear panel

（1）Chassis ground；

（2）Power plug, supporting AC 100V~240V power supply, 50~60Hz；

（3）Power switch;

（4）network interface, connect PC, on-line editing and command receiving and sending control;

（5）RESET: System reset button;

（6）RS232:communication interface, to connect the external central control equipment/ support camera

tracking;

（7）RS485：support camera tracking;

（8）GPIO：order transfer. For the specific connection mode, see GPIO setting in the 2.3 & appendix;

2.3 GPIO

G: Ground

1~8: Port 2-8 are freely configurable input or output, port 1 only input function.

V: The default GPIO power output pin(5V).

GPIO state of software:

Note: ●Output high; ●Input high; ● Output low; ● Input low ● Disable

Port output: each output port is OC output, the default reference voltage 5V and the reference voltage can

also be

external is less than 15V, take the default reference voltage, the total output ports is 200mA:

Input port: lowest level of input high > 2V, highest level of input high <VCC+0.7V; highest level of input

low <0.3V.

Use of GPIO:

the output: is a parameter matrix of internal changes (such as mute), cause the change of the

output level of a

GPIO output pins, to drive an external circuit.

Audio matrix internal change -> GPIO pin level change ->external driving circuit.

input: GPIO is an input pin level due to changes in the external circuit is changed, thus a

parameter matrix trigger changes.

The external circuit state changes -> GPIO pin level change -> audio matrix internal change.

The operation details see Appendix 2.
