National Instruments 781630-01 Instrument Control Device

National Instruments part number 781630-01 is an identifying part number for the GPIB-ENET/1000, an Ethernet GPIB Instrument Control Device. This instrument is an IEEE 488 controller designed for computers with an Ethernet port functionality. This device facilitates the sharing of a single GPIB system among multiple networked users or the control of several test systems from one networked host. It comes with a password-protected web interface for easy configuration and can manage IEEE 488 devices from any Ethernet-based (LAN) TCP/IP network, including Gigabit, 100BASE-TX, and 10BASE-T. Each GPIB-ENET/1000 interfaces and shares up to 14 GPIB devices across multiple network hosts. 

Additionally, a single computer can control up to 100 GPIB-ENET/1000 interfaces. The device comes with a license for NI-488.2 driver software, ensuring maximum reliability when connecting to third-party instruments with GPIB. A single computer can control up to 100 National Instruments GPIB-ENET/1000 devices. This GPIB controller has DHCP capability, allowing it to automatically acquire network configuration. 

The unit reverts to Auto IP addressing and assigns itself an IP address in the 169.254.x.x range in case of DHCP failure. The device requires 250 mA at 12 V typically, and up to 500 mA at 12 V maximum. This high-performance device supports various operating systems, including Microsoft Windows, Mac OS X, and Linux. The NI GPIB-ENET/1000 has data transfer rates of up to 1480 Kbytes per second in 3-wire mode and up to 5600 Kbytes per second in HS488 mode. 

The connector options on this device include a GPIB interface adhering to the IEEE 488 standard with a 24-pin configuration, ensuring compatibility with industry-standard communication protocols. For Ethernet connectivity, it features an RJ-45 port with integrated LEDs for visual network status indication. Physically, the device measures 21.0 cm in length, 12.7 cm in width, and 3.7 cm in height. It weighs 394 grams (13.9 ounces), making it suitable for various applications where reliable and robust connectivity is essential.
