Particular for the development of devices which are communicating in a local Ethernet network (LAN), i.e. at the control-unit development, the Ethernet Repeater PTH is essential. There are diagnostics at the network data transmission possible, which cannot be done with an Ethernet Switch.

With the ONE -to- ALL PORT transmission of the Ethernet Repeater PTH, the total network traffic is always on all network ports and members assured. Thereby is no interaction to the data transmissions i.e. a routing decision as by an Ethernet Switch.

The Ethernet Repeater PTH is manufactured by Nickl as a 4 port- and as a 8 port- variant. The 8-port variant can be configured as one 1(x) 8-Port Ethernet Repeater (HUB) or as two (2x) apart 4-Port Ethernet Repeaters (HUBs).

The power supply with 9..36VDC, i.e. directly from the vehicle, is galvnically decoupled to prevent ground loops.
OPTIONAL is a 5VDC supply via USB possible, for this a USB-connector is placed at the manufacturing instead of the D-Sub-5.
