Overview

Product overview

Key product information and technical features.

The ENET-232/4 provides network access to four point-to-point RS-232 connections. It belongs to NI's ENET-232 serial server family rather than the Compact FieldPoint module platform.

Software selection is important for this legacy interface: NI-Serial 14.0 removed support for NI Serial ENET devices. NI also documents a version-dependent NI-VISA access method for previously configured devices.

Four RS-232 ports for network-accessible serial communication.
10BaseT and 100BaseT Ethernet connectivity through an RJ-45 connector.
DB-9 serial connectors with DTE port configuration.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

Does NI-Serial 14.0 support the ENET-232/4?

No. NI states that NI-Serial 14.0 removed support for all NI Serial ENET interfaces, including the ENET-232/4.

How are serial ports addressed through NI-VISA?

NI documents the resource format ASRL::IPAddress::PortNumber::INSTR, with ENET-232/4 ports numbered 1 through 4. The device must first be configured and assigned an IP address from a system with suitable NI-Serial support. Check the intended NI-VISA version's readme for compatibility.

What is the maximum RS-232 transfer rate?

The archived manufacturer manual specifies 230.4 kb/s. Actual throughput depends on the system, network, and connected instrumentation.
