6-wire standard cable, up to 0.5mm² stranded wire, with max.
250nF/km, 750µH/km and minimum 34ohm/km has 22µH/
ohm. However, the length of the cable (flexibly installed) is
limited to under 25m by the RS-232 specifications. 6-wire
cable, type PR6136 (Lmax = 1.1mH/km; Cmax = 220nF/km;
Rmin = 26 ohms/km: 43µH/ohm): under 25m (see above).
