NOTE
The splice and wire nut must be completely immersed into the
silicon gel inside the splice tube to be waterproof.
2) Mount the surge protector box to a flat surface within 5 feet of the PC's
serial port. Ground the center terminal to an earth (or building) ground
using the 14 AWG wire.
3) Connect the 5-foot patch cable from the surge box to the Rad Modem.
Fasten the cable to the strain relief tab with a cable tie. Connect the Rad to
the PC's serial port with the 9-to-25 pin serial cable.
