WirelessHART Device TypesWirelessHART Device Types
WirelessHART divides into 2 main device types
WirelessHART GatewayWirelessHART Device
Every HART device can become a WirelessHART device by connecting a WirelessHART adaptor to it

Some Laptops do support “Auto cross over”functionality
In this case a cross over cable OR an straight trough cable can be used
In case “Auto cross over” is NOT supported there are two possibilities
Direct connection between WHART GW and Laptop/PCConnection via a Hub or Switch

There are two types of plug availableT568A and T568B
Both can be used for straight through and cross over cable
