Internet.

Connect the WAN interface of the REX 100 (P1 WAN) with a patch cable with the
higher level (company) network/router. The LAN ports P2 to P4 are available for
connection to the machinery network.
1. Introduction
The REX 100 is an industrial router suitable for worldwide remote access to IPv4-en-
abled devices (PLCs, HMIs, IP cameras, etc.) It is mounted on the DIN rail. This Quick
Start Guide explains the basic conguration of the REX 100 router. The conguration
is created in the myREX24 V2 portal and then transferred to the REX 100.
Important advance information: Please use the latest version of the dial-up software
“shDIALUP” (as of version v3.7 R1.0). You can acquire it as a download at www.helm-
holz.de. For successful connection with the myREX24 V2 portal, REX 100 routers require
at least the rmware status V1.5.0 or newer.
