ACCES' model PTRC-AT Bus Expansion Kit allows you to expand your personal computer system without timing or noise problems. It provides software-transparent, active, 16-bit Bus extension between the computer and a separate expansion chassis, operator-less station, or cell controller. This bus expansion kit uses active circuits and high-speed logic to minimize propagation delays. Also, multilayer printed circuit boards are used and the design is optimized for proper impedance match to avoid spikes and ringing.

The kit consists of two cards and an interconnect cable. The expansion transmitter card (PT3-AT) plugs into the host computer and the expansion receiver card (PR3-AT) plugs into an expansion chassis backplane. All that is required in the expansion chassis is a properly terminated backplane (up to 20 slots) and an appropriate size power supply. Power should be applied near-simultaneously to both the computer and the expansion chassis. This is easily accomplished by connecting both units to the same power strip. A one-meter long, shielded cable interconnects the two cards and mates with connectors on the card mounting brackets.
