PERSONAL488 Controllers

The Personal488 family of PC/IEEE 488 controllers offers drivers for all popular programming languages and operating systems, from the high-performance Windows® 95, Windows NT, and Windows 3.x drivers, to the easy-to-use HP-style DOS device and subroutine drivers. What's more, the Personal488 family has been expanded to include IEEE 488.2 interfaces for most popular PC buses and communication ports. New additions to the Personal488 line include the Personal488/PCI, a 1 Mbyte/s PCI-based IEEE 488 controller with digital I/O; the Personal488/ATpnp, a plug-and-play 16-bit AT-compatible IEEE 488 controller; and the Personal488/CARD, a PC-Card that brings full IEEE 488 control to notebook and desktop PCs.  Personal488/PCI

ANALYSER488

Analyser488, the first IEEE 488 analyser of its kind, can capture and analyse IEEE bus transactions at up to 1 Mbyte/s, the highest speed allowed on the IEEE 488 bus. The built-in vacuum fluorescent display provides convenient hexadecimal, binary, and descriptive alphanumeric information on every bus transaction. The unit can capture and store up to 32,000 transactions in its nonvolatile memory—it can even be unplugged and transported to another location for data retrieval and analysis. Captured data is easily output to any computer via the Analyzer 488 serial port.

EXTENDER488

The Extender488 provides an economical solution to the 60 foot (20m) distance limitation of the IEEE bus. Using high-speed 115.2K baud serial data transmission, a pair of extenders can stretch the bus up to 4,000 ft (1,000 meters). The Extender488 operates transparently to the IEEE controller, requiring no special programming, with the exception of Parallel Poll which must be performed twice due to the speed specification of the IEEE bus. The number of devices that can be controlled on the bus is doubled by the extenders. Both the local and remote bus can have up to 14 devices each, in addition to the extenders.  Extender488


SERIAL COMMUNICATIONS BOARDS

Serial Communication Boards for PC/AT computers which offer multi-channel serial I/O capability via RS-232, RS-422, RS-485, and current loop. All of the boards in this family use an enhanced compatible version of the industry-standard 16550 UARTs, which include built-in 16-byte FIFOs to ensure data integrity. The single- and dual-channel boards can be configured for any available COM address, offering compatibility with DOS and Windows NT/95 applications without the need for additional software drivers. The four- and eight-channel boards include DOS and Windows NT/95/3.x drivers.  Serial Communications
