Where two prefabricated cable ends meet at the same device, join the male and female ends (see

below).

If a prefabricated cable will be at the end of the bus (requiring termination, as explained), and you

want to use a prefabricated terminating resistor, make the cable installation so that a female

connector will be locat ed at the device where the cable wil l be t er m inated.
