Serial cable connection on a Palm device: This kit contains a RF shielding ferrite block and a serial cable adapter. Add the RF shielding ferrite block to your Palm cradle or serial cable: As close as possible (2-3 inches) to the end of the cable near the Palm device/cradle, wrap two turns of cable in the ferrite block and close the block and secure with the provided "tie wrap".
Connect the 9 pin end of the adapter to the 9 pin cable from your Palm cradle or serial cable. Connect the other end of the adapter to the rear left serial I/O connector on the frequency generator. Do not use an extension on this cable. The cable provided with your PDA and the adapter are shielded and have an RF filter. Adding an extension to this cable can cause the frequency generator to malfunction.
