Connector Assembly & Maintenance
To allow you to choose the particular peripherals to use (such as power
supply, modem, and external clock), and suitably locate them, REF TEK
typically does not always supply complete cables with your recorder.
Instead, REF TEK supplies a kit that contains the mating connectors that you
need to construct the cables required by your particular peripherals and
system configuration. Upon order, REF TEK will supply any or all of our
standard connector cables (as described later). Also, REF TEK will construct
any custom cables your system needs. For some of the more standard
connector/cable drawings of commonly used assemblies see “Standard
Faceplate Connections”.
Pin connections are supplied in your recorder manual (Starting in Chapter 1,
“Overview”). When making the connections follow industry standard
practices in dressing the cable end, soldering the connections and applying
shrink tubing. The use of self-vulcanizing tape is preferred to potting the
connector since with potting, the connector is no longer field serviceable.
Note: For additional moisture protection, apply DL-111 inside the top shell to seal
against the rubber grommet. Bottom shell must rotate freely after the top shell
has been firmly tightened into the connector body.
The recommended periodic connector maintenance and usage is as
follows:
1.
Plugs labeled “PT06” have a superintending outer locking collar with a machined
inner groove that locks onto the pegs in the side of the panel mount mate
receptacle. When removing a PT06 connector, move it out of the locked position
by first applying a downward force on the outer collar and then twisting it free in
a counter-clockwise direction.
2.
Be careful with tools when gripping connectors - use tools with nylon fittings in
the jaws if you can, and do not apply excessive force.
3.
The connectors have a machined groove inside. To avoid damaging this groove,
you must apply a downward force while turning. Because connectors for the 130
DAS units are constructed of an alloy, excessive force on the locking groove can
cause burrs which make subsequent installation and removal of the connectors
more difficult.
4.
Do not attempt to remove a plug with pliers.
5.
Assemble new connectors correctly as shown below.
