Daftar/Tabel -- network buses

Daftar/Tabel -- electrical characteristics of single collision domain segment "slow speed" network buses:

The number of nodes can be limited by either number of available addresses or bus capacitance. None of the above use any analog domain modulation techniques like MLT-3 encoding, PAM-5 etc.

PSI5 designed with automation applications in mind is a bit unusual in that it uses Manchester code.
