"enable MIC setting" option.
Example:
Switch in the video camera with address 2 at RS232 interface, and switch in a MIC at the input channel 1 and 8 respectively
(it is required that the preset point 1 be associated with the MIC of channel 1, the preset point 2 be associated with the
MIC of channel 8, and the video camera turn to the MIC of the corresponding input channel). The setting process is as
follows:
Connect PC with the device, and open the serial port setting in the device setting. Select 232 for the serial port number,
and select 9600 for the baud rate. The check bit, data bit and stop bit shall not be changed, click "save".
A. Associate the preset point 1 and channel 1: (1). video camera settings: select 232 for the serial port number; select 2 for
the video camera address; set the preset point 1; select the protocol in accordance with the actual device; adjust the upper,
lower, left, right, focal length, light ring and other parameters, to align the video camera with the MIC of input channel 1,
and click save button to save the save the preset point; (2) preset point control setting: select 1 for MIC number; select 2
for video camera address; select the protocol in accordance with the actual device; select 232 for the serial port number;
set the preset point 1. Click enable the MIC setting; Click OK..
B. Associate the preset point 2 and channel 8: (1). video camera settings: select 232 for the serial port number; select 2 for
the video camera address; set the preset point 2; select the protocol in accordance with the actual device; adjust the upper,
lower, left, right, focal length, light ring and other parameters, to align the video camera with the MIC of input channel 8,
and click save button to save the save the preset point; (2) preset point control setting: select 1 for MIC number; select 2
for video camera address; select the protocol in accordance with the actual device; select 232 for the serial port number;
set the preset point 2. Click enable the MIC setting; Click OK..
After two MICs and video camera are associated, select enable tracking and set the tracking threshold value, to realize the
voice tracking control.
6）GPIO
A. GPIO Setting
The rear panel of the audio matrix device has GPIO muddle with DB25 socket. The output channels of the upper part of
the DB25 socket are channels 1~8 (whose original state is high level output), among which channels 5~8 are OC
(open-collector) output with reference (driving) voltage of +12 V and maximum output current of 60 mA, and channels
1~4 are common level output with reference voltage of 3.3 V. The maximum output current is 0.4 mA when it outputs
high level and -30 mA when it outputs low level.
The input channels 1~8 of the GPIO are located in the lower part of the DB25 socket of the GPIO module. The inner part of
the module is equipped with put-up resistor, so the module supports 3.3 V-12 V inputs.
