I/Os: Precautions
NOTICE
Damage to the camera or connected peripherals
The PoE implementation is non-isolated.
Therefore, when the camera is powered by PoE:
• Only connect the pins 3, 4, 5, 6 and 10 (isolated I/Os).
•
Do not
connect any other pins of the TFM connector.
NOTICE
Damage by reverse polarity
If Alvium G1 cameras are externally powered with reverse polarity, the cameras
can be damaged.
Power Alvium G1 cameras according to the specifications described in this chapter.
NOTICE
Damage by serial communication voltage levels
If you are using serial communication (UART, similar to RS232), keep voltage levels
in the range defined in
on page 131. Typical RS232 voltage levels (such as
±10 VDC) are not supported without external circuitry.
I/O cables maximum length
The maximum length for I/O cables must not exceed 30 m.
Signal level
Consider this when you connect external devices to your camera, for example, to
trigger lighting:
• The default signal level for isolated GPO2 is low at camera startup.
• The default signal level for non-isolated GPIO0 and GPIO1 is high at camera
startup.
Use the
LineConverter
feature to configure I/Os and GPIOs for your needs.
