P90
P90 uses RS232 as its bus. RS232 is specified in ANSI EIA/TIA-232-F.
To connect the RS232 bus, use a shielded pair of wires for the data lines (RX and TX) and an
additional wire for signal ground (GND).
The maximum cable length for RS232 is 15 m for standard cables, e.g. JY(ST)Y cables with
100 pF/m. If you need to cover larger distances, use a cable with a low capacity. A cable with half the
capacity has twice the maximum length.
Example calculation: A Cat7 cable with 40 pF/m allows a length of 15 m • 100 pF / 40 pF = 37.5 m
