ITxPT Label Report



The ultra-compact and robust Ethernet switch is the perfect solution for tight spaces in buses and trams. The managed switch offers a total of 4 Gigabit ports for Ethernet backbone and broadband applications. Furthermore, it has bypass relays to maintain data traffic in case of a switch failure in the network. ROQSTAR 4GE+12FE Managed is a configurable Layer 2 switch. It supports Layer 2 functions such as VLANs and port-based DHCP. It also provides diagnostic data of the IP network and can send an alarm to the backend in case of a failure. The unit is housed in a robust metal enclosure and has M12 connectors for a secure data transmission.



ROQSTAR Gigabit Managed is an Ethernet switch designed for public transport applications. The switch can be configured via an easy-to-use web interface and via a USB interface connection. The Layer 2 switch has management functions to realise network segmentation and redundant ring topology networks. It can also be used for automatic IP address configuration. With its high port density, it is particularly suitable for retrofitting public transport vehicles.

Typical applications:

  • On-board passenger Wi-Fi
  • Realtime passenger information systems
  • Gigabit backbone for CCTV
  • Automatic IP address configuration
  • Segmentation of networks for critical data like contactless payment systems
  • Passenger counting systems


Enables Gigabit backbone in public transport vehicles

Diagnosis during operation via SNMP and ITxPT Inventory and xStatus

Uniform IP addresses in vehicles through NAT

Plug & play replacement of IP devices

High availability due to ring redundancy
