GPIB Controlled GPIB Bus Switch

ICS's 4842B GPIB Bus Switch shares GPIB instruments with multiple Controllers or lets one Controller control three GPIB buses.

The Model 4842B is a GPIB controlled Bus Switch that makes it easy for two or three controllers to control a common set of instruments of for a single controller to control two or three GPIB buses and up to 39 instruments.

Model 4842B GPIB Bus Switch

Photo- 4842B GPIB Bus Switch • Operates as a 1:2 or as a 1:3 bus switch, permitting a single
controller to operate up to three IEEE 488 Bus systems.

• Operates as a 2:1 or 3:1 multiplexer so two or three bus controllers can share a common set of GPIB instruments.

• Has its own GPIB Address for easy control by the test program.

• Transparent, high data transfer rate does not affect existing programs.

• Adds up to 39 devices to your test system.

• 1 U high, rack wide case easily mounts in your test system rack.

• Includes rack mounting ears, a universal power supply and maual.

GPIB to Ethernet Instrument Interface

ICS's 4865B GPIB to Ethernet Instrument Interface adapts instruments with Ethernet interfaces to GPIB test systems.

ICS's 4865B provides a VXI-11 compliant interface for instruments that support the VXI-11 protocol and a smart, user-configurable, raw socket protocol that accommodates most instruments that use raw sockets. The 4865B replaces our earlier Model 4865 and is 2x to 5x faster than the original Model 4865. Click here for the original 4865 webpage.

ICS's 488-SERIAL module provides three Serial to GPIB functions for controlling GPIB devices and interfacing serial devices with the GPIB bus. The 488-SERIAL combines the best features of our 4895 Serial to GPIB Controller and our 4894B GPIB to Serial Interface in one small module.

488-SERIAL Serial-to-GPIB Controller and Interface Module

Photo- 488-SERIAL Serial to GPIB Controller

• 3 Serial to GPIB conversion modes in one small module.Improved flexibility.

• S-Mode uses serial commands to control multiple GPIB devices. Makes any serial source a 488.2 GPIB Controller.

• New command complete prompts return command and error status to user. A real serial protocol for controlling GPIB devices prevents command overruns.

• C-Mode sends serial commands to and reads responses from a GPIB device Limited control of a single GPIB device.

• G-Mode adds a GPIB interface to any device with a serial port.Transparent data transfer.

• Supports RS-232, RS-422 and RS-485 signals. Versatile serial interface includes Xon/Xoff and hardware handshaking.

• Easy configuration from the serial port or GPIB bus. Use any controller.
