Page 5: General Information
The user can specify an IP address for the oscilloscope and the N4865A will attempt to connect to it. If the N4865A's AutoFind function is enabled, the N4865A will do an UDP broadcast and attempt to connect to the ﬁ rst VXI-11.3 compatible oscilloscope that replies to the broadcast. When the N4865A has established VXI-11 channel connections to the oscilloscope, the N4865A is then ready to accept GPIB bus commands and device speciﬁ...
Page 6 The N4865A and its companion oscilloscope can be placed anywhere on the GPIB bus following the cabling guidelines in the IEEE-488.1 Standard. In addition, you can have multiple N4865A's on a GPIB bus, each with its unique GPIB address. ICS's N4865A Interface is packaged in ICS's small metal Minibox™ case which provides proven EMI/RFI protection and rack mounting capability.
Page 7 MODEL N4865A SPECIFICATIONS 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 label on your unit. N4865A - X General Model Number...
Page 8 GPIB Addresses The N4865A's GPIB primary address is entered and saved in ﬂ ash memory when the unit is conﬁ gured. Conﬁ guring is done via the N4865A's Ethernet Interface. Primary address range is 0 - 30. The default GPIB address is 4.
Page 9 1.4.8 Device Clear and Selected Device Clear When the N4865A receives a Selected Device Clear or a Device Clear on the GPIB bus, it sends a device_clear RPC to the companion oscilloscope and device_clear RPC to the companion oscilloscope and device_clear clears its GPIB talk and GPIB listen buffers.
Page 10 RPC to the companion oscilloscope to obtain the Status Register response and assert the GPIB SRQ signal. The SRQ signal is deasserted when the N4865A is Serial Polled or when the N4865A learns that the companion oscilloscope has deasserted its MSS bit.
Page 11: Ethernet Interface
The N4865A has the capability to accept an address from a DHCP Server. If the N4865A is set to DHCP and does not receive a IP address, it defaults to a Class B AutoIP address of 169.254.48.65 with a Net Mask of 255.255.0.0.
Page 12 1.5.6 HTML Pages The N4865A's standard HTML pages conform to HTML version 4.01 or XHTML version 1.0. The required pages are needed for correct WebServer operation. User can redeﬁ ne the other page names, page layouts or add additional pages.
Page 13 ﬁ rst VXI-11.3 compatible oscilloscope that replies. Connection capability is determined by the network topography. If AutoFind is Off, no UDP broadcast is issued and the N4865A will try to link to an oscilloscope at the user designated ip address.

Page 33 3.2.1 Oscilloscope Discovery and Linkage At power turn-on, the N4865A performs a selftest for 4 seconds and then blinks its GPIB address. If the N4865A is set for dynamic IP addressing, it attempts to locate a server for 15-20 seconds before defaulting to its Auto IP address of 169.254.48.65.
Page 34 If AutoFind is disabled and the N4865A has been conﬁ gured to use a speciﬁ c oscilloscope IP address, then the N4865A does not do a UDP broadcast and instead attempts to communicate directly with a VXI-11.3 oscilloscope at the designated IP address.
Page 35 The N4865A periodically queries the companion oscilloscope's Status Byte to update its own Status Byte at a low 3 Hz rate. If the N4865A discovers that the oscilloscope is no longer asserting its MSS bit, then the N4865A will deassert the SRQ signal on the GPIB bus and turn off its SRQ LED.
Page 36 IP address of 169.254.48.65. Select Static to operate the N4865A at a ﬁ xed IP address and then enter the desired IP address, Net Mask and Gateway values. Enable AutoFind for easy linking to any oscilloscope.
Page 37 GPIB input buffer as part of the clearing process. The N4865A may miss multiple DC or SDC commands when sent to it at high speed. If multiple Device Clears are required, provide a minimum 100 mil- liseconds delay between commands.
Page 38 3.3.5 Transferring Large Files The N4865A transfers large data ﬁ les in blocks of one Talk buffer or one Listen buffer worth of data at a time. These buffers are a maximum of 1,024 bytes. Users should set their program to read data in blocks that are multiples of 1,024 bytes for best performance.

Page 42 16-bit data bus from the ARM7 Proces- sor. The N4865A has a LAN Interface, a static 1 Mbyte RAM chip, a FLASH, a GPIB Interface and a LED Latch chip, all controlled by an ARM7 Processor.
Page 43 The power supply is a switching regulator that converts the unregulated DC input to +5 volts DC to run the N4865A’s peripheral logic chips. A 3.3 regulator regulates the 5 Vdc down to 3.3 volts to power the processor and major logic chips.

Page 45 MAINTENANCE The N4865A does not require periodic calibration and has no internal adjust- ments. However, if the N4865A is used in an application where the IEEE 488 bus cables are frequently changed, the N4865A's IEEE 488 Bus Connector may occasionally require cleaning to remove wax and dirt buildup. New bus connectors are shipped with a brightener (thin wax like ﬁ...

Page 49 SELF TEST ERROR CODES At power turn on, the N4865A conducts a selftest of its major components. The test takes about 5 seconds. During the selftest the PWR LED is on and the RDY LED is off. A successful test ends when the RDY LED on. Test failures are indicated by the blinking LED patterns shown in Table 5-3.
Page 50 RESETTING TO DEFAULT NETWORK SETTINGS The N4865A can be reset to the default network settings listed in Table 1-2 by holding the rear panel LAN Reset Button in for 10 seconds while turning the N4865A’s Power Switch on. Connect the supplied AC adapter to the N4865A and to an AC power outlet.
Page 51: Updating The Firmware
UPDATING THE FIRMWARE The N4865A's ﬁ rmware can be updated in the ﬁ eld without returning the unit to the factory. Connect the N4865A to a Windows PC as described in paragraph 2.5.1. Connect the supplied USB power cable to the N4865A and to one of the computer's powered USB ports.

Page 57 Bus Commands are transmitted when ATN is asserted. The commands are listed in the message columns in Table A-1 (on the left hand page) which shows the relationship between the commands and ASCII data characters. ASCII data characters have the same code values as bus commands but are transmitted with ATN off.

Page 66 A1.3.3 Variables and Channel Lists SCPI variables are separated by a space from the last keyword in the SCPI command. The variables can be numeric values, boolean values or ASCII strings. Numeric values are typically decimal numbers unless otherwise stated. When setting or querying register values, the decimal variable represents the sum of the binary bit weights for the bits with a logic '1' value.
