WaveJet 300A Remote Control Manual
1. INTRODUCTION TO WAVEJET 300A REMOTE CONTROL INTERFACES
The WaveJet 300A supports remote control through USB, GPIB and TCP/IP. USB is supported as a standard
feature, GPIB and TCP/IP are available with optional interface boards.
The WJ-A-GPIB and WJ-A-LAN are optional interface boards exclusively for the WaveJe 300A series.
• Insert the board into one of the option slots on the rear of the WaveJet 300A 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-A-GPIB and the WJ-A-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-A-GPIB or
WJ-A-LAN interface board.
ESD Sensitive
The WJ-A-GPIB and WJ-A-LAN interface boards are sensitiv e to electrostatic discharge
(ESD). To avoid causing damage to the boards, always follow anti-static procedures (wear
wrist strap, etc.) when handling the boards.

1.3 WaveJet 300A USB Hardware
The USB interface is standard on each WaveJet 300A oscilloscope. Note that the front panel USB port (located
next to the power button) is for use with USB memory devices for saving waveforms, screen i mages and setup files.
The rear panel USB port is the remote control interface. The WaveJet can be connected to a computer wit h a USB
A/B cable.
Use of the WaveJet 300A USB hardware requires the installation of a USB driver on the computer. The WaveJet
300A USB drivers are included on the CD shipped with the WaveJet and are also available for download from the
Software Utilities page on the LeCroy website.
Note: LeCroy’s Scope Explorer software (version 2.25 or greater) includes the WaveJet 300A USB driver. Installing
Scope Explorer will accomplish steps 1 through 7 belo w automatically. Scope Explorer can be downloaded from the
Software Utilities page on the LeCroy website. Scope Explorer provides an easy way to transfer waveforms, setup
files and screen captures from the WaveJet oscilloscope to the PC.
1. Save/Extract all the files from the USB driver set to a directory on your computer
2. Connect the WaveJet 300A oscilloscope to a USB port on the computer and power the WaveJet on.
3. The Found New Hardware Wizard will begin, it will ask for permission to connect to Windows Update to search
for software, select No, not this time.
4. On the following screen select Install from a specific list or specific location
5. The next screen will prompt you to search for the driver, select Don’t Search, I will choose the driver to install.
6. Browse to the location of the drivers and click OK. The drivers will install and a completion messa ge will appear
when the installation process is complete. Click Finish.
7. The WaveJet 300A USB driver installation is now complete.
8. Enable the USB port on the WaveJet oscilloscope by entering the Utilities menu. Inside the Utilities menu select
Remote > Interface > USB

WaveJet 300A Remote Control Manual
2. INSTALLATION OF GPIB AND TCP/IP
The Remote Function uses GPIB, TCP/IP and USB 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 (GPIB and TCP/IP)
The WaveJet remote control interfaces, WJ-A-LAN and WJ-A-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
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-A-LAN and/or WJ-A-GPIB interfaces into the slot and fasten the screws.
4. Turn the WaveJet power on and then press
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
7. For TCP/IP use the ADJUST knob to set the IP address. Rotate the knob to change values; push the knob to
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-A-LAN and WJ-A-GPIB installed, or with only one interface card
installed. However, two GPIB or two LAN cards cannot be installed simultaneously.
ADJUST knob to set the appropriate GPIB address.

• 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.

5. RESPONSE FORMATS
The following response formats are provided according to the settings of the DTFORM an d 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 uni t 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>.
