Compliance, safety, and intended use
45Alvium G1 User Guide V1.7.0
I/Os and power supply by PoE
The PoE implementation is non-isolated. Therefore, when the camera is connected
to a PoE-capable Ethernet port:
• Only connect the pins 3, 4, 5, 6 and 10 (isolated I/Os) of the TFM connector.
• Do not connect any other pins of the TFM connector.
See Camera interfaces on page 196 for details.
I/Os
To avoid damage to the camera, keep the maximum values for
• Isolated I/Os: Input voltage below 24 VDC, output current below 20 mA per
output.
• Non-isolated GPIOs: Input voltage below 5.5 VDC, output current below
12 mA.
See Alvium G1 model specifications on page 58 for details. The maximum length
for I/O cables must not exceed 30 meters.
GigE connection
GigE NICs
To avoid damage to GigE NICs and injectors, make sure that PoE power sourcing
equipment is at least compliant to IEEE 802.3af.
Ethernet cables
Proper cable handling enables reliable performance:
• We recommend Category 6 (CAT6) or higher rated Ethernet cables for Alvium
G1 cameras. A different rating may not sustain peak interface bandwidth;
leading to lost connectivity or dropped frames coming from the camera. .
• Use only shielded cables to avoid electromagnetic interferences.
• Please use cables recommended by Allied Vision.
• Avoid unnecessary bending to prevent damage to the cables.
• Avoid coiling to prevent electromagnetic interference.
Power supply via I/O cables
If you power the camera via an I/O cable, consider the voltage drop to meet the
minimum supply voltage for the camera.
