Reference Manual ATOM one SSM500
3.2.3
Microphone Input
The microphone connector is a standard 3.5 mm stereo jack. It supports 2.5 V phantom
power for electret microphones (see
audio_micbias
command for details).
The audio will be inserted into all SDI signals.
3.2.4
RJ45 Ethernet Connector
The network connector is reserved for future applications like control via IP. At the moment
it can only be used for firmware updates (see chapter 4.2).
3.2.5
SD Card Slot
The ATOM one SSM500 has a SD card slot on the right side. This slot is used for firmware
updates. Details can be found in chapter 4.3.
3.3 Over-Temperature Protection
The ATOM one SSM500 has a compact design which includes an efficient air cooling
solution. Still the device will get warm during heavy load. To protect the device the camera
will switch to a low power state when the internal CPU temperature reaches 90°C. This
stops all record and playback and powers down the image processor.
To recover from this state the device temperature has to fall below 70°C Keep in mind that
as long as you did not improve the cooling the camera will probably reach the temperature
limit again after a short time.
If the low power state does not cool down the camera and the temperature reaches 100°C
the device will shut down completely. You can only recover from this state by turning the
device on again via the power button.
Note:
During normal operation the camera should never reach the 90°C limit. If your
device reaches this limit repeatedly, please check the operating conditions (e.g. ambient
temperature, other devices generating heat nearby, access to fresh air for cooling).
To keep track of the current CPU temperature use the
temp
command. The camera also
logs the maximum CPU temperature which can be read out using the
max_temp
command. You can reset the logged maximum temperature using the
max_temp_reset
command.
Every time the camera reaches the 90°C temperature limit, an over temperature counter
will be incremented. You can read the counter value by using the
over_temp_count
command. This counter value is persistent and can not be reset by the user.
3.4 Status LEDs
The device has two status LEDs.
The right LED labeled “Sys” shows the general status of the system:
