Connecting Pepperl+Fuchs' Remote Monitor (RM) Series

...with VNC (Virtual Network Computing)

This tutorial is for RealVNC Server. Refer to the guide for UltraVNC Server.

This tutorial assumes that you know how to set up a PC for an IP address, how to use the ping command, and how to make an Ethernet connection between two PCs or a PC and remote monitor.

Connect the PC and RM in the same network domain, e.g., 192.168.100.XXX, or within your internal domain address structure.

Communication setup

Start VNC Server on the server side of the unit. You can use any VNC package you want, but for this example we use RealVNC.

VNC Server service mode screen

Enable a password. VNC Server must be password protected or it will not operate. Initially, it is easiest to get going with a VNC password as authentication rather than using the Windows password option. Once a reliable connection is established, you can go back and adjust the security parameters of the program to meet specific security needs. Click the button called More on RealVNC and open the VNC Server – Options window.

On the connections tab, set Authentication and Encryption. Refer to the RealVNC User Guide for additional information. You can set up the screen as shown below. The screen is functional provided that you have a good Ethernet connection. If you receive an “authentication error” message from VNC, start with this screen. Don’t forget to configure the VNC password with something easy to remember for this test.

Set your VNC password

Note: You may want to adjust the inbound and outbound ports on your Windows firewall to allow communcation on port 5900. Port 5900 is the default VNC communication port. You see above that VNC is expecting you to accept communcation on port 5900.

Multimonitor sharing

If you are sharing monitors, which is an important, typically used feature of VNC, you need to configure a number of options.

Go to VNC Server > More > Options ? Expert tab: 

Configure options to share monitors

Configure the following:

  • AlwaysShared
  • NeverShared
  • DisconnectClients
  • Shared

Depending on the combination of these options, the screen below will specify whether connections are exclusive or concurrent:

Confirm options to share monitors

This configuration should get you up and running.

Refer to the RealVNC User Guide for more information on the RealVNC side of the communication:

RealVNC User Guide

The Pepperl+Fuchs Remote Monitor (RM) shell

Create a profile on the RM. Refer to the user guide for more information on creating a VNC profile. Once you open the editor to create the VNC profile, you will get the Notepad editor. You need to make only one line of change in the profile.

Remote Monitor shell

Enter the server IP address on the RED line above. It doesn’t hurt or help you to have a password on the BLUE line. I always delete the password on the BLUE line, but leave password=  alone.

Once complete, save this profile as you exit the Remote Monitor configuration screen.

Click (or tap if you have a touch screen) on your VNC-named program on the RM screen. Note: If you need the on-screen keyboard to complete a password entry (e.g., you don’t have a physical keyboard), make sure to invoke the OSK (on-screen keyboard) before you start.

VNC Authentication

To start a remote VNC session, insert your password from the keyboard or the OSK and press/tap/click Log On. The remote VNC session should start.
