2. Provide low voltage 12VDC for front-end device.
3. When transmission distance is long, to avoid output voltage dropping too much, also provide 48~56VDC power
supply for slave unit, at the same time master unit also gest power from it.
4. When connect 12VDC power supply for master unit, because long distance causes output voltage to drop too much,
it can’t satisfy slave unit power requirement, also provide 12VDC power supply for slave unit as supplement.
Tips: The power consumption supports PoE / Non-PoE equipment power supply standard, due to the difference of line
loss and transmission distance, it may not be able to meet simultaneously two kinds of power supply requirement, only
through dip switch setting to choose one kind of power output mode.
When you use VC-350PoE-2P, please follow the below tips as a reference, in order to reduce the fault in the process of
using and the inspection work.
1. The device supports auto-negotiation allocation master and slave. It also can be set master-slave side and grouped
by the software. Each group (one point to multi-point communications group) only allows one Master, others are Slaves.
Otherwise, the network data won't be able to transmit.
2. Signal transmission cable must be the copper cable. Other material cables will cause the decrease of signal
transmission quality and distance.
3. Long-distance cable connections must be by standard connection method, such as welding or using connectors.
4. Make sure the electrode of transmission cable is consistent, otherwise, it is easy to cause the power failure.
5. Please choose matching power adaptor (12VDC or 48～56VDC).
6. There is no waterproof design for this product, please make sure that it is used in dry environment.
7. If device fails, do not disassemble or repair it by yourself. Please contact us timely.
