As documented in the Serial Hardware and Software Help
, ENET support for these operating systems is through NI-VISA only. You will thus not be able to use NI-Serial directly.
NI-VISA support means that the device can still be used from one of these systems with VISA commands, but NI-Serial cannot be installed or used to configure the device. Check the ReadMe file for the version of VISA installed on your target for compatibility with the Serial ENET devices.
To access the ENET-232 and ENET-485 devices from the one of these targets, the ENET device must first be configured from a system with NI-Serial and assigned an IP address. For details on configuring the ENET device, reference the ENET-232 and ENET-485 User Manual
In Measurement & Automation Explorer (MAX), only devices that support NI-Serial will be able to add the serial ports under the Devices and Interfaces
category. This means the ENET-232/485 ports will not be visible in Devices and Interfaces
. They will also not be visible under Remote Systems
because they are not dedicated to a specific target.
For use on VISA targets, the ports must be accessed from the calling program by their complete VISA resource name. When using the VISA Open
function to open a connection to the port, use the following VISA resource string format to access the ENET ports:ASRL::IPAddress::PortNumber::INSTR
For example, the ENET-232/4 has four RS-232 serial ports, numbered 1-4. If your ENET-232/4 had an IP address of 10.0.0.1
, and you were attempting to access port 2, your VISA resource name would be:ASRL::10.0.0.1::2::INSTR

Windows XP 64-Bit is not supported in any version of VISA.
