Page 4: Introduction
Prologix GPIB-USB Controller User Manual 1. Introduction Prologix GPIB-USB controller converts any computer with a USB port into a GPIB Controller or Device. In Controller mode, Prologix GPIB-USB controller can remotely control GPIB enabled instruments such as Oscilloscopes, Logic Analyzers, and Spectrum Analyzers. -
Page 5: Configuration
Details on how to configure these tools are available at prologix.biz. 5. Configuration Prologix GPIB-USB controller can be configured using any of the following methods: Prologix.exe – Prologix.exe is an open source tool developed by John Miles for configuring the controller. Web link to the tool can be found at prologix.biz. -
Page 6: Device Mode
All data received from the host over USB is buffered until the GPIB controller addresses Prologix GPIB-USB controller to talk, at which time the buffered data is passed along to the GPIB port. The controller can buffer only one command. A subsequent command received over USB will overwrite the previously buffered one, if the previous one has not yet been transmitted over GPIB. -
Page 7: Binary Data Transmission
The ++eot_char command may be used to detect GPIB EOI signal assertion. 7.1. Binary Data Transmission Prologix GPIB-USB controller can send and receive binary data to and from GPIB enabled instruments. No special action is necessary to receive binary data from instruments. Any binary data received from the instrument is transmitted over USB to PC unmodified, just as with ASCII data. -
Page 8: Commands
GPIB address depends on the operating mode of the controller. In CONTROLLER mode, it refers to the GPIB address of the instrument being controlled. In DEVICE mode, it is the address of the GPIB peripheral that Prologix GPIB-USB controller is emulating. -
Page 9: Clr
Prologix GPIB-USB Controller User Manual Read-After-Write, saves the user from having to issue read commands repeatedly. This command enabled or disabled the Read-After-Write feature. In addition, auto command also addresses the instrument at the currently specified address to TALK or LISTEN. ++auto 0 addresses the instrument to LISTEN and ++auto 1 addresses the instrument to TALK. -

Page 11: Eot_Char
MODES AVAILABLE: CONTROLLER 8.10. lon This command configures the GPIB-USB controller to listen to all traffic on the GPIB bus, irrespective of the currently specified address. This configuration is also known as “listen-only” mode. In this mode, the controller can only receive, but cannot send any data. -
