Configure a File Transfer Protocol (FTP)
Data Port Range
With Rosemount MON2020

Quick Start Guide March 2022
1 Configure a file transfer protocol (FTP) data
port range
When gas chromatographs (GCs) are installed behind a router through port
forwarding, it can be useful to configure an FTP data port range. With this
feature, GCs will be differentiated by their ports, but will have the same
Internet protocol (IP) address.
Note
This feature has been added to Rosemount 370XA, 700XA, and 1500XA GCs
with firmware version 4.1.1 or newer.
If using port forwarding (for example, if the GC is connected behind a cellular
router), set the FTP data port range when Rosemount is connected locally to
a GC with a DHCP connection.
This feature will only be enabled if:
• Rosemount is connected to a GC.
• The user logged into Rosemount has admin rights.
• The Security switch is unlocked.
• The Designate Port option is selected.
