Installing the K144XV Phase Lock Board
Anti Static Protection Required
We strongly recommend you take the following anti-static precautions (listed in order of importance) to avoid
ESD (Electro Static Discharge) damage:
Leave ESD-sensitive parts in their anti-static packaging until you install them. The packaging may be a
special plastic bag or the component’s leads may be inserted in conductive foam. Parts which are
especially ESD-sensitive are identified in the parts list and in the assembly procedures.
Wear a conductive wrist strap with a series 1-megohm resistor. If you do not have a wrist strap, touch a
bare metal ground briefly before touching any sensitive parts to discharge your body. Do this frequently
while you are working. You can collect a destructive static charge on your body just sitting at the work
bench.
WARNING
DO NOT attach a ground directly to yourself without a current-limiting
resistor as this poses a serious shock hazard. A wrist strap must include a 1-
megohm resistor to limit the current flow. If you choose to touch an
unpainted, metal ground to discharge yourself, do it only when you are not
touching any live circuits with your other hand or any part of your body.
Use a grounded anti-static mat on your work bench.
No soldering is required but if you choose to use a soldering iron for any reason, be sure your iron has
an ESD-safe grounded tip tied to the same common ground used by your mat or wrist strap.
Preparing for Installation
Tools Required
1. #0 and #1 size Phillips screwdrivers. To avoid damaging screws and nuts, a power screwdriver is not
recommended. Use the screwdriver that best fits the screw in each step.
2. Soft cloth or clean, soft static dissipating pad to lay cabinet panels on to avoid scratching.
The following tools are strongly recommended:
1. ESD wrist strap.
2. Static dissipating work pad.
3. Long (needle) nose pliers or sturdy tweezers (for handling small cables in tight spaces)
Firmware Required
You must have Firmware version 1.03 or later available for loading into the K144XV, the special RS232 cable
used with the K144XV for updating firmware, and your computer available. The Phase Lock Board will not
function without the new firmware.
