The NI-488.2 software for Mac OS is a comprehensive set of programs
and drivers. It simplifies the job of programming the GPIB-ENET/100 to
function as an IEEE 488.2 (GPIB) Controller with complete
communication and bus management capabilities.
NI-488.2 also includes a GPIB interactive control utility; the Macintosh
Programmer's Workshop (MPW) C, THINK C, and Metrowerks
CodeWarrior C language interfaces; and a shared library for
C programmers developing applications for the PowerPC platform.

Description
Flashes rapidly at start-up while performing self
tests and when acquiring network parameters.
A steady yellow state indicates the box is ready
for operation. Slow flashing pattern indicates an
error occurred.
Indicates the GPIB-ENET/100 detected a twisted
pair (10Base-T or 100Base-TX) link. The color
indicates the connection speed. If yellow, the speed
is 10 Mbits/s. If green, the speed is 100 Mbits/s.
Indicates the GPIB-ENET/100 is transmitting to
the Ethernet network.
Indicates the GPIB-ENET/100 is receiving
Ethernet network traffic.
Indicates the GPIB-ENET/100 is configured as a
GPIB Talker.
Indicates the GPIB-ENET/100 is configured as
a GPIB Listener.
