LAN Adapter is a hardware module that provides

The Model N4865A is designed to interface with and control Agilent DSO/

MSO7000 Series and DSO/MSO9000 Series oscilloscopes. The N4865A

has two ways to connect to an oscilloscope after power turn-on and selftest.

The user can specify an IP address for the oscilloscope and the N4865A will

The N4865A follows the IEEE-488.2 Message Exchange Protocol when

handling GPIB commands and device messages and should only be used with

IEEE-488.2 compatible GPIB Controllers. GPIB commands are converted to

VXI-11.3 equivalents and transmitted to the companion oscilloscope. Device

The N4865A can accept reverse channel Service Requests and will assert SRQ

The N4865A's operation and network settings are completely programmable

by commands from its Ethernet interface, eliminating the need to open the unit

to change or verify a function setting. The setup parameters can be changed

the N4865A to its default network settings at any time.

The N4865A and its companion oscilloscope can be placed anywhere on the

ICS's N4865A Interface is packaged in ICS's small metal Minibox™ case which

provides proven EMI/RFI protection and rack mounting capability. Rear panel

RJ-45 and GPIB connectors provide access to the network and GPIB bus. Front

panel LEDs provide visual network and GPIB bus status and diagnostic help

The following speciﬁ cations apply to all N4865A models. Options for your

unit may be found by comparing the list below to those listed on the Ethernet

N4865A - X General Model Number

The N4865A's 488 Bus interface meets the IEEE STD 488.1-1987 standard

SH1, AH1, T6, L4, SR1, PP0, DC0, RL0, DT0, C1 - C4 and C9

The N4865A's GPIB Bus drivers incorporate powerup/down protection to

prevent sending invalid data to the bus. GPIB fanout is up to 14 devices.

Primary address range is 0 - 30. The default GPIB address is 4.

All device data messages sent to the N4865A must be terminated with EOI

RPC. When the

N4865A is addressed to talk, it sends a

Large Listen messages are handled by holding off the GPIB bus while a buffer

reading multiple talk buffers worth of data from the oscilloscope and outputting

them to the GPIB bus until a response packet is received from the oscilloscope

Note 1. Working buffer size may be smaller if the companion oscilloscope reports smaller maximum

packet sizes in its

response.

When the N4865A is transistioned to the Listen Active State from the Talk

Active State, it discards any data in the GPIB talk buffer. Similarly, when the

N4865A is transistioned to the Talk Active State from the Listen Active State,
