A crimper block can be used to connect both transmit and receive grounds from the RJ45 cable to
the single signal ground on the DB25. The connector internally splices the two wires together and
provides one wire into the DB25 connector as shown below:
Figure J-3: Wire Splicer
To splice the wires, cut off the end of the wire that does NOT extend through the connector and
insert both wires into the connector. Make sure that the wire that does not extend through the
connector is in as far as possible to ensure a solid connection. Make sure that the wire that does
extend through the connector extends far enough on the other side to be inserted in to the DB25
connector. Carefully squeeze the connector using a pair of pliers to make sure it is fully latched.
