1. INTRODUCTION

The WJ-GPIB and WJ-LAN are interface boards exclusively for the WaveJet3xx series.

• Insert the board into one of the option slots on the rear of the WaveJet3xx before use.

• It can be inserted into either of the two option slots provided.

• Once the board is inserted into the slot, the WaveJet main unit automatically recognizes it as a remote

interface, allowing you to select it.

• The WJ-GPIB and the WJ-LAN can be inserted at the same time, but only one of them can be selected.

• Two of the same kind of interface board must not be inserted at the same time (prohibited).

CAUTION!

To prevent damage to the instrument, turn instrument power OFF before inserting a
WJ-GPIB or WJ-LAN interface board.

ESD Sensitive

The WJ-GPIB and WJ-LAN interface boards are sensitive to electrostatic discharge (ESD).
To avoid causing damage to the boards, always follow anti-static procedures (wear wrist
strap, etc.) when handling the boards.

2. INSTALLATION OF GPIB AND TCP/IP

The Remote Function uses GPIB and TCP/IP as the interface. GPIB is installed according to IEEE488.1 and
IEEE488.2, while TCP/IP is installed according to LeCroy VICP.

WaveJet Remote Control Interface Installation Procedure

The WaveJet remote control interfaces, WJ-LAN and WJ-GPIB are compatible with all WaveJet units running
firmware version 3.06 or higher. For firmware upgrades please visit www.lecroy.com. The firmware and firmware
installation instructions are available for download.

1. Confirm the installed firmware version is 3.06 or higher. To do this press U
Status and Update and then select Update. If it is 3.06 or greater proceed to step 2. If not please update the
firmware.

2. With the power off, remove the screws from the rear panel option slot.

3. Insert the WJ-LAN and/or WJ-GPIB interfaces into the slot and fasten the screws.

4. Turn the WaveJet power on and then press U

5. In the Utilities menu a new selection, Remote will be available, if two cards are installed there will be a choice
between TCP/IP and GPIB. If only one is installed there will only be one listing.

6. For GPIB operation use the A

7. For TCP/IP use the A
jump from field to field. The WaveJet works with static IP addressing only.

8. Press the soft key next to the down arrow to move to Subnet Mask and Default Gateway. Rotate the knob to
enter values; push the knob to change fields.

9. After entering the correct addresses, press Enter at the bottom of the remote menu and reboot the scope.

The WaveJet can be operated with both WJ-LAN and WJ-GPIB installed, or with only one interface card installed.
However, two GPIB or two LAN cards cannot be installed simultaneously.

DJUST knob to set the IP address. Rotate the knob to change values; push the knob to

DJUST knob to set the appropriate GPIB address.

2.2 Device behavior when the address is changed outside the range 0 to 30

• With GPIB, values that do not fall within the range of 0 to 30 cannot be selected.

• TCP/IP has 4 fields, IPv4, for which values that do not fall within the range of 0 to 255 cannot be selected.

2.3 When a user-initiated address change is recognized by the device

• GPIB immediately recognizes the address change.

• TCP/IP recognizes the change when the system is rebooted after the change.

2.4 Device setting at power-on, including commands which modify the power-on settings

• At power-on, device settings are restored to their values when the device was last powered off.

• A command for changing the power-on settings is not installed.

5. RESPONSE FORMATS

The following response formats are provided according to the settings of the DTFORM and DTBOARD commands.
The number of data to be transferred may vary depending on the settings of the DTSTART and DTPOINTS
commands.

(1) The DTFORM command is set to "BYTE/WORD" (binary transfer):

#8 <byte-length> <binary-block>

• #8 shows that the response message is described in the format of <Definite Length Arbitrary Block
Response Data> and that the content of the following <byte_length> is an 8-digit ASCII string.

• The contents of <byte_length> represents the number of bytes to be entered into <binary_block>. The
byte length should always be a sign-free, 8-digit integer including zero.

• The contents of <binary_block> represents the waveform data stored in the product's internal memory
in binary code.

[Example of data]

# 8 0 0 0 0 1 0 2 4 D0 D1 - - - Dn

1024-byte binary data (D0, D1,..., Dn) is transferred.

(a) The DTFORM command is set to "BYTE":

• Since one unit of data is transferred in one byte, the number of bytes meets the number of transfer
data specified using the DTPOINTS command.

[Example of data]

# 8 0 0 0 0 1 0 2 4 D0 D1 - - - Dn

1024-byte binary data is transferred, and Di (i = 1, 2,..., n) corresponds to one unit of data.

Note 1: For average waveforms, only upper bytes are transferred, even though these waveforms are word
data.

Note 2: For math waveforms, word (for ADD/SUB/FFT) or double word (for MULT) data is transferred even
though the DTFORM setting is BYTE.

(b) The DTFORM command is set to "WORD":

• Since one unit of data is transferred in two bytes, the number of bytes to be transferred is twice as
large as the number of transfer data specified using the DTPOINTS command.

[Example of data]

# 8 0 0 0 0 2 0 4 8 U0 L0 U1 L1 - - - Un Ln

• 2048-byte binary data (U0, L0, U1, L1,..., Un, Ln) is transferred.

• Two bytes Ui and Li (i = 1, 2,..., n) correspond to one unit of data.

• For channel waveforms other than averaged, Li (i = 0, 1, …, n) becomes 0.

• The DTBORD command is used to specify the byte order. When L/H is specified, the data is

transferred in the order of Li, Ui (i = 0, 1,..., n).

(2) The DTFORM command is set to "ASCII":

<ascii_block> <delimiter>

• <ascii_block> contains block data. The waveform data units stored in the product's internal memory
are described in the format of <NR1 Numeric Response Data> one by one, and these data units are
respectively separated by a comma.

[Example of data]

D0, D1,..., Dn

Di (i = 0, 1,..., n) is described in the format of <NR1 Numeric Response Data>.

• Current cursor measurements are displayed in
<measure1> to <measure7> in
<NR3 Numeric Response Data> format.

• When the cursor mode is disabled or the data cannot
be measured, the query returns +9.91E+37.

• Seven types of cursor measurement results are output,
respectively separated by a comma, regardless of
whether cursor mode has been selected. For items not
covered by the measurement, the query returns
+9.91E+37.

When MATH is FFT, M1:TRA is ON and CURM is VATH, CMSR?
returns frequency at the cursor of the FFT waveform for
<measure7>.

REMARKS When calculating the cursor measurement values of the

YT display Amplitude, Value at Cursor, and XY display
