Introducing DS-18xLAN - Fast Multiport Ethernet Switch With PTP Synchronization

The DS-18xLAN is an 18-port network switch that supports high-speed connectivity up to 10 Gbps. It features a PTP synchronization mechanism and offers a passive PoE option for powering external Ethernet devices.

The front panel utilizes twelve 2.5 GbE ports with a passive PoE option. There are three options for the front panel connectors:

  • DS-18xLAN-RJ45-L1B: six RJ45 connectors and 6x LEMO 1B 8-pin female connectors

  • DS-18xLAN-L1B: twelve LEMO 1B 8-pin female connectors

  • DS-18xLAN-RJ45: twelve RJ45 connectors

The default configuration for passive PoE is that front panel ports with LEMO connectors have the passive PoE option turned ON and RJ45 front panel ports are configured with passive PoE turned OFF. The passive PoE option can also be user-configurable for each port.

A 2.3 A current limit for each front panel port makes it possible to connect up to 12 SIRIUSi-XHS-PWR devices running PWR+DATA+SYNC over a single cable.

The back panel has 4x 2.5 GbE ports with RJ45 and 2x SFP slots with up to 10 Gbps network speed.

DS-18xLAN network switch comes in SIRIUS form factor chassis making it easily stackable with SIRIUS-XHS DAQ devices.

One key feature of our new network switch is the Precision Time Protocol (PTP) synchronization (IEEE 1588v2). This enables users to easily configure and distribute Dewesoft DAQ systems, such as SIRIUS XHS, SIRIUS XHS-PWR, and OBSIDIAN. It also supports the connection of other network devices, like cameras, ensuring perfect synchronization. With a 10 Gbps uplink, high sampling rates for data acquisition are achievable with uninterrupted throughput.
