![]() ![]() To be safe, it is better to have a margin factor of 2. The material and the construction of the cable also play a part in the length of the cable. Please note that this is only a general guide. The following table is a general guide to the cable length base on the baud-rate. The shorter length will keep the capacitance lower which makes it harder for the higher-frequency signal to be coupled over to the adjacent cable. The insulation between wires is capacitance which high-frequency signals can easily pass over. To reduce the effect of induced noise from the adjacent wire, the length is kept shorter. The noise can be in the form of garbage data on the adjacent data wire. This baud-rate is low and the cable length distance can be up to about 150 meters (about 500ft).Īs the speed of data transmission increases on the cable, the physical signal of the data can easily be coupled to the adjacent wire. ![]() The RS232 often uses a data baud-rate of 9600bps. ![]()
