Setup 

3.1 

Install Configuration Software 

All the network setup and configuration of the module is achieved by means of the 
ProSoft PLX50 Configuration Utility. This software can be downloaded from: 

www.prosoft-technology.com

. 

 

Figure 3.1. - ProSoft PLX50 Configuration Utility Environment 

3.2 

Network Parameters 

The module will have DHCP (Dynamic Host Configuration Protocol) enabled as 
factory default. Thus, a DHCP server must be used to provide the module with the 
required network parameters (IP address, subnet mask, etc.). There are a number of 
DHCP utilities available, however it is recommended that the DHCP server in the 
PLX50 Configuration Utility be used. 

Within the PLX50 Configuration Utility environment, the DHCP server can be found 
under the Tools menu.
