Quick Instructions

The Bonding Buddy DSL far end connection testing equipment comes in a water-resistant bag and only needs to leave the bag when the batteries needs changing.

Unzip the bag, pull out the leads and clip them to your cable pair. The Bonding Buddy stays at the cross-connection , giving you tones for each pair of wires.

Follow the instructions on the Bonding Buddy for the testing.

Just zip up the bag and toss back into its place when you are finished.

Help a cable technician save time and work by "manning" the other end of 2 cable pairs that are being tested.

It is both a Far End Device (FED) and dual trace tone generator.

It provides two unique tracing tones, one for each pair.

It can be commanded from the other end of the cable pair to open the pairs or short the pairs to ground for testing.

For mechanical shock and weather resistance, the bonding buddy enclosure is protected by a rubber boot and a water repellent canvas bag. The modular connector and LED are located such that the bonding buddy can be used while still inside the canvas bag.

Double insulated case

Electronic components protected with water resistant coating

Transient protection

Protected from talk battery and ring voltages

Handles 200 volts during open test

Handles up to 1 amp of AC or DC fault current during every other mode

How to use it

In Inclement weather:

Zip up the bag to the very end where the cord comes out. This will protect the Bonding Buddy from getting moisture inside. Hanging the bag from its loop means the cord comes out of the low end and will make sure water runs off instead of in.

Installing Batteries:

Remove the yellow boot from the case

Remove battery cover

Insert (4) AA batteries

Replace cover and boot

Power up:

Connect the 5 alligator clips to two cable pairs and to ground.

Plug cable into Bonding Buddy. This will connect and power up Bonding Buddy.

The LED will flash GREEN once every 2 seconds while the battery is good. It will flash RED once every 2 seconds if the battery is low.

Tracing Tones:

Pair one will have a 1000 Hz beep repeating at 3 Hz rate.

Pair 2 will have 2 fast 1000 Hz beeps, the pattern repeating at 3 Hz rate.

The tones will be ½ the frequency when the battery is low.

If one of the pairs stays shorted for more than 14 seconds, both pairs will have identical very short beeps; one per second.

Open Pair Test:

If you short either pair for three to six seconds, the Bonding Buddy will send an “Open Test warning”; 8 upgoing beeps on both pairs, 1 per second, then open both pairs for 60 seconds.

Shorted Pairs test:

If you short either pair for seven to twelve seconds, the bonding buddy will send a “Short Test Warning”; 8 downgoing beeps on both pairs, 1 per second, then short both pairs to ground for 60 seconds.

After a 60 second test period, normal tones will resume.

If you short either pair even for an instant while a warning tone is active, Bonding Buddy will abort the test mode and immediately return to its normal tracing tone mode.

Battery Saving Features:

If a short on either pair lasts longer than 15 seconds, Bonding Buddy will assume that a pair is shorted and put out a very short beep on both pairs once per second. When the short goes away, Bonding Buddy will automatically resume normal operation

After 3 hours of no shorts detected, Bonding buddy will sleep quietly to save batteries. Shorting either pair for more than 5 seconds will wake it up again.

Any time the modular cable is unplugged, power will be off.
