We started with the PT-901 (A24 D16). Then we switched to the PT-902 (A32 D32). Then we switched to the Hal Versa repeater. The cabling of the PT-902 did not work in our system. It uses round cable, about 0.5" in diameter and large D connectors. These did not fit in our box or in the Sun-3 at the other end. While we (and P-T) were busy redesigning complex cables to fit both ends, the Hal-Versa unit came out and solved the problem for us. They use special controlled-impedance flat cables with standard ribbon headers on the ends. The Hal-Versa also has about 1/3 the number of chips and is therefore cheaper than the PT-902. They all work fine though.
