4896 GPIB Quad Serial Interface The 4896 is a four channel IEEE 488 GPIB/HP-IB to serial interface that adapts up to four serial devices to the GPIB bus. Each serial channel has been designed for independent, full duplex operation at rates up to 115.2 K baud. Large 60 K byte buffers are assigned to each channel to buffer the data. High speed DMA transfers move the data between the buffers and the GPIB interface at rates >600 Kbytes per second. This high data transfer rate coupled with large buffers in each channel, minimizes GPIB transfers and frees the bus controller for other tasks. Typical applications are adding serial channels to workstations, driving a mix of serial devices and modems from a GPIB bus and/or buffering data from remote devices.

• High speed, 115.2 K baud channels include 60 K byte buffers. Large data buffers in each channel.
• > 600 K byte/sec. GPIB data transfer rate. Minimizes GPIB Bus time.
• SCPI commands set and query non-volatile serial channel configurations. Configure the unit without having to remove the cover or remember cryptic commands.
• LCD display shows Bus activity, buffer status, serial interface signals and channel settings. Built in status display and diagnostic aid.
• Includes a menu-driven PC compatible configuration program. Steps user through configu-ration choices.
• New 1 U high, metal case has CE approval Smaller size with full EMI/RFI protection.

4899 GPIB to Modbus Interface The Model 4899 GPIB<->Modbus Interface is an IEEE 488.2/GPIB to Serial Interface that adapts Modbus slave devices to the GPIB or HP-IB bus.The 4899 lets the user send simple read-write messages on the GPIB bus to control and query slave Modbus devices.The 4899 does all of the Modbus message formatting and error checking.The 4899 has both RS-232 and RS-485 interfaces so it can be connected directly to a single Modbus slave device or it can be connected to multiple Modbus devices via an RS-485 network.

Features:

• Converts simple ASCII commands into Modbus RTU messages. Relieves user from having to format messages and do CRC checking.
• Provides both single ended RS-232 and balanced RS-422/RS-485 serial signals. Connects to single and multiple Modbus devices.
• GPIB Interface is IEEE-488.2 Compliant. Meets latest GPIB Standards.
• GPIB Address can set by SCPI commands Avoids having to open the case to set the address.
• Saves GPIB and serial interface settings in an internal E 2 ROM. Configure unit without having to remove the cover.
• Front panel LEDs show address and status. Visual indication of operation and test status
• Small 1 U high,metal box design has CE approval Small size with full EMI/RFI protection.

4860/62 Bus Isolator and Expander The 4860 GPIB<->GPIB Isolated Bus Expander solves four of the most common problems encountered in GPIB systems, device loading, signal noise, ground loops and cable distance. The 4860 provides this capability in ICS's small Minibox size case. The Model 4862 is a lower cost Bus Expander for applications that do not require electrical isolation.

4842 Bus Switch
The Model 4842 GPIB Bus Switch is a GPIB controlled switch that enables several GPIB Controllers to share one or more GPIB device(s)or lets a single GPIB Controller operate multiple Bus systems.The 4842 is basically a GPIB controlled A-B-C switch for the GPIB bus.When used as a Bus Switch,the 4842 lets a GPIB controller connected to the common port select and control devices attached to the numbered ports.When used as a Multiplexer,the 4842 lets Bus controllers connected to the numbered ports share the common bus and any devices attached to it.

4886B-H Long Distance Bus Extender
The 4886B Bus Extenders allow you to establish an IEEE 488 Bus at the site of your test and measurement application wherever it may be located - whether in another room, at remote test site or around the world.
The 4886B uses twisted shielded pair cable or external modems and the direct dial telephone network to extend the bus to the remote location. The 4886B supports both point-to-point and multiple sites with hardwired cables and external modems. Communication between the sites is serial with the 4886B providing RS-232 and RS-449 (RS-422) compatible interfaces. ICS's proprietary error-detection and correction firmware provides error free data transmission over systems with BER rates as low as 1 part in 10⁴.

• Supports point to point or multi-drop site systems
• Automatic Error Detection / Correction algoritm to maximize data transmission rate and secure valid data
• Transparent to existing software - requires only minimal program changes

4889 A/B/L Hi-speed Long Distance Bus Extender
ICS's Model 4889 Series Bus Extenders dramatically improve IEEE 488 bus use by pro-viding GPIB bus extension up to 25 km at data rates of 300 Kbytes per second. Through the use of ICS's patented protocol, the 4889's bus transfer rate remains unchanged as the bus extension distance increases - even for distances out to 25 km. This enables long distance, high speed data transfer from computer-to-computer or to remote devices over the GPIB bus.
