Fig. 2-10 V.24/20 mA Interface — Cable lengths
It is assumed that there are only slight differences in potential (-2 V < V
diff
< +2 V) between sending and receiving device (applies only to the V.24
interface).
It is also assumed that the interface modules of the partner device are of
a quality that is at least equal to that of the R500 computer interface mo-
dule.
Do NOT route data transmission lines parallel and adjacent to power li-
nes.
