c Verification
Use a multimeter to test the reliability of the cable
components.
● Connector jacks can't be short-circuited.
● Connections between the metal shell and the connector jacks
can't be short-circuited.
● Cable core wires are connected properly to the corresponding
connector jacks.
d Protection
The device is placed outdoors, warp up the connector using three layers of PVC insulation tapes to prevent it from being
damaged, as shown in the following figure.
CAUTION
● Each radio connector must be wrapped by three layers of waterproof tape and three layers of insulating tape.
● Wrap the tape from bottom to top, from top to bottom, and then from bottom to top. Cut the tape after wrapping three
layers of tape on the connector.
● Wrap each layer of tape tightly and ensure that each layer covers more than 50% of the layer below it.
● Before wrapping the waterproof tape, stretch the tape evenly until the tape turns 1/2 as wide as before.
● After wrapping the tape, bundle cable ties at both ends of the insulating tape to prevent aging of the tape.
