(depends strongly on physical setup)

ZZ ZZ 9999999 ZZ ZZ 9999999 9999999

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.
