Symbols and Their Meaning in This Manual
READ THIS MANUAL: To gain knowledge of the Link product, user must read
and understand the operator’s manual before using this product. There are
features known to the user, only if the manual is read.
The lightning flash with arrowhead symbol, within an equilateral triangle, alerts
the user to the presence of “dangerous voltage” within the product’s enclosure
that may be of sufficient magnitude to constitute a risk of electric shock to
persons.
The exclamation point within an equilateral triangle alerts the user to the
presence of important operating and maintenance (servicing) instructions in the
literatureaccompanying the appliance.
This symbol represents a protective grounding terminal. Such a terminal must
be connected to earth ground prior to making any other connections to the
equipment
The fuse symbol indicates that the fuse referenced in text must be replaced with
one having the ratings indicated.
Page 2 of 11

•
To prevent damage to equipment when replacing fuses, locate and correct the
trouble that caused the fuse to blow before applying power.
•
Verify that all power supply lights are off before removing power supply or servicing
equipment.
•
Use only specified replacement parts and follow static precautions at all times when
handling this equipment.
•
Leave the back of the frame clear for air exhaust cooling and to allow room for
cabling. Slots and openings in the cabinet are provided for ventilation. Do not block
them.
•
This product should be powered on as described in the manual. To prevent
equipment damage select the proper line voltage at the ac input connector as
described in the installation documentation.
•
To prevent damage to this equipment read the instructions in this document for
proper input voltage range selection.
•
To reduce the risk of electric shock, ensure that the two power supply cords are
each plugged into a separate branch circuit.

Circuit boards in this product are densely populated with surface mount and ASIC
components. Special tools and techniques are required to safely and effectively
troubleshoot and repair modules that use SMT or ASIC components. For this
reason, service and repair of Link products incorporating surface mount technology
are supported only on a module exchange basis. Customers should not attempt to
troubleshoot or repair modules that contain SMT components. Link assumes no
liability for damage caused by unauthorized repairs. This applies to both in- and outof-warranty products.
North American Power Supply Cords
This equipment is supplied with molded grounding plug (NEMA 5-15P) at one
end and molded grounding connector (IEC 320-C13) at the other end. Conductors
are CEE color coded, light blue (neutral), brown (line) and green/yellow (ground).
Operation of this equipment at voltages exceeding 130 VAC will require power
supply cords which comply with NEMA configurations.
International Power Supply Cord
This equipment is supplied with molded grounding connector (IEC 320-C13) at
one end and stripped connectors (50/5 mm) at the other end. Connectors are CEE
color coded, light blue (neutral), brown (line) and green/yellow (ground).
Other IEC 320-C13 type power supply cords can be used if they comply with the
safety regulations of the country in which they are installed.
Note:
This equipment has been tested and found to comply with the limits for a class
“A” digital device, pursuant to Part 15 of the FCC Rules. These limits are designed
to provide reasonable protection against harmful interference when the equipment
is operated in a commercial environment. This equipment generates, uses, and
can radiate radio frequency energy and, if not installed and used in accordance
with the instruction manual, may cause harmful interference, in which case the
user will be required to correct the interference at his own expense.

PORTABLE CC DECODER
MODEL PCD-88
The PCD-88 is the standard closed caption decoder for field one line 21 decoding.
The toggle switch on the left end selects CC1 or CC2 only. The GPI only turns off
the closed caption data. The power remains on and the captions are displayed
with the GPI open. The closed captions are turned off when the GPI is closed. A
3.5mm male plug is included for the remote control function.
The input video is high impedance loop through. If the video input is not looped on
to another product, the remaining BNC must be terminated with 75 ohms. One 754
ohm termination is included. The PWT-300 is included also.

PCD-85 GENERAL DESCRIPTION
The PCD-88 is a high performance closed caption decoder for the NTSC
system. It is capable of processing and displaying standard line 21 Field one
closed captions.The two channels of data are CC1 and CC2. The two channels
are selected from a toggle switch on the end of the unit. Two LED's on the end
panel indicate which CC channel is selected.
This unit can easily be placed along side a video monitor that does not have a
built-in closed caption decoder to accomplish excellent results.
A toggle switch on the end panel allows the user to select between the two
caption channels, CC1 and CC2. The PCD-88 is designed with the professional
user in mind. The required input signal is baseband video at 1 Vp-p with
caption data on line 21 of field one. There are two 75 Ω BNC composite video
outputs. The input is high impedance looping configured for single ended
operation, AC coupled, to work in all environments. The PCD-88 operates on
12VDC, or a regulated wall transformer at 12VDC. The Link Electronics model
PWT-300 power supply operates on a line voltage of 110 to 220 VAC, and is
included.
Three internal controls provide for adjustment of composite video level,
background level and character intensity.
The PCD-88 is housed in a compact and rugged portable case for reliable
performance. All Link products are backed by a ten-year warranty including
parts and labor.
