The network parameters of NET 1 to NET 6 interfaces can be changed through MasterTool Xtorm.
For further information on configuration and network parameters changes, see Ethernet Interfaces
Configuration .
Free ARP
The NETx Ethernet interface promptly sends ARP packets type in broadcast informing its IP and
MAC address for all devices connected to the network. These packets are sent during a new
application download by the MasterTool Xtorm software and in the CPU startup when the
application goes into Run mode.
Five ARP commands are triggered within a 200 ms initial interval, doubling the interval every new
triggered command, totalizing 3 s. Example: the first trigger occurs at time 0, the second one at 200
ms and the third one at 600 ms and so on until the fifth trigger at time 3 s.
Network Cable Installation
Hadron Xtorm Series CPUs Ethernet ports are identified on the panel from NET 1 to NET 6. These
ports have standard pin outs, which are used, for example, in PCs. The connector type, cable type,
physical level, among other details regarding the CPU and the Ethernet network device are defined in
the Technical Description - Ethernet Interfaces.
Figure 3-21 and Table 3-7 present the RJ45 Hadron Xtorm CPU female connector, with the
identification and description of the valid pin out for 10Base-T and 100Base-TX physical levels.
