DS-EISK5GH0B - 1

SHEET 5-Port Skorpion Gigabit Diagnostic Switch Plug and Play Diagnostic Switch for Protocol Debugging One benefit of switched Ethernet technology is that the switch restricts directed messages to only those ports party to the communication. This improves overall network throughput by not burdening end stations with useless traffic. However, this feature makes protocol debugging difficult because a protocol analyser tool attached to an unused port on the switch cannot observe any directed messages of interest. In the past, the solution was to change out the switching hub with a repeating hub but with the Skorpion Gigabit Diagnostic Switch this is unnecessary. The EISK5-GT/H retains all the virtues of switched Ethernet technology such as 10/100/1000 Mbps data rates on individual segments, auto-negotiation, Auto-MDIX — but with one exception: no address learning. All messages — directed, multicast, broadcast — are flooded to all ports on the switch allowing a protocol analyser tool such as Wireshark® the ability to observe all traffic on the network. The EISK5-GT/H can be permanently installed on an installation or replaced with a regular Skorpion switch once a system is commissioned. This device can also be useful when developing embedded Ethernet devices because you can connect the Skorpion Gigabit Diagnostic Switch between two embedded Ethernet devices and view their messages using Wireshark.

DS-EISK5GH0B - 2

Overview The EISK5-GT/H can be used for control panel installations where one needs the ability to diagnose problems in the field. It can also be used in a development environment when debugging code. A metal DIN-rail clip attached to the aluminium enclosure can survive the toughest installation. A writable side label allows the installer an opportunity to document field cabling locations right on the unit. The EISK5-GT/H is powered from a source of either 24 VAC ±10% or 10–36 VDC. With redundant power connections, a backup power scheme can be supported. A removable power connector...

Power Considerations Applied voltage must be 10-36 VDC or 24 VAC ±10% and deliver a current commensurate with power consumption. The recommended size for solid power conductors is 16-20 AWG; and for stranded conductors use 16-18 AWG. Zero volts (COM) is isolated from chassis (earth). Input connections are reverse-polarity protected. Connecting chassis to earth or using a backup source is always optional. All options shown are for use in Class 2 circuits if applied voltage is limited to 30V DC. AC Powered with AC Powered with Redundant DC Grounded Secondary DC Backup Powered Typical...
