The connection of several device pairs via the same cable can lead to transmission problems due to crosstalk between the different signals in the cable. Ideally, therefore, each device connection is realized via separate cables. If several cables have to be lined up on a connection section, it is important to carry out these transitions technically as well as possible. This means that ideally professionally assembled RJ45 connectors are used for the transitions. If this is not possible, e.g. when using telephone cables, care should be taken to unwind the stranding of the wire pairs as short as possible. The contact between the wires of the cables to be connected must be as good as possible. Shielded cables can cause problems due to potential equalisation currents. In particular, we do not recommend grounding the shields in the central unit when combining several cables in one central unit.
|supply voltage||Power supply via PoE, the device cannot bei supplied locally.|
|operating temperature||-40 up to +75°C|
|copper ports||1 x 10/100BaseT, RJ45|
|extender ports||1 x RJ45, 1, 2 or 4 pairs|
|transmission cable||Ideale type: Cat5e and superior
Further types:When using Cat3 cables (telephone cable) or bell wire, the possible distances are significantly reduced.
If Cat7 cables are used, the same distances can be expected as for Cat5e/Cat6. The shielding of the Cat7 cable must not be earthed.
|Transmission distance||The maximum transmission distance when using Cat5e cable or superior is approx. 500m.
When transmitting PoE, the power loss of the transmission distance must be taken into account.
