LTC Input
Figure 8
Longitudinal Time Code (LTC) input: Green is an input XLR plug that expects
LTC with a nominal +4dbu analog signal.
This time code can be sent out its communication port (s) so that captioning software
can triggered from this input or the unit can send out a trigger for the software.
Note: If you are sending out time code the baud rate of 4800 is recommended, because
the baud rate of 1200 is not fast enough and 2400 may not be either.
Weather Lift GPI
Figure 9
Weather lift GPI: Green requires a 3.5mm male mono audio plug that is
activated when shorted. Optional Weather lift GPI plug available upon request.
The PTC-892 provides a “weather lift” function to comply with federal regulations
requiring captioning not interfere with emergency information scroll. This capability will
automatically “move” the captions up one thru four lines when activated. The “lift” is
provided for all captioning, CC1 to CC4, whether it is local captioning or pass thru from
another source.
The weather lift function in the PTC-892 is implemented with several options
available to the user. Its front panel selection can be used to set the amount of “lift” or
the amount of lift can be set by the ^AW command (see software instruction set)
through communication ports. The ^AW commands over-rides the front panel selection.
^AW0 - no lift lines selected.
^AW1 - one lift line selected.
^AW2 - two lift lines selected.
^AW3 - three lift lines selected.
^AW4 - four lift lines selected.

PTC-892 Main Display
Figure 13
Captioning Decoder Mode: This section displays which open captions are on the
decoder's output. Right now it shows that CC1 is being decoded.
Data Recovery Mode: Displays what captions are recovered and send out the port(s).
Right now it shows that data recovery is off.
Input Detection [I/O Format]: Displays if input detected and whether NTSC or PAL.
Also displays selected input and output formats, if analog input selected the I/O formats
will be the same. Right now it shows no input with composite selected as the I/O format.
Captioning Encoder Mode: Displays what mode the encoder is in. F1 = Field 1, F2 =
Field 2, T = Transparent, I = Insert, M = Monitor, O = Opaque, and N = Newswire. Right
now it shows Field 1 and Field 2 to be in Transparent mode.
The different encode modes are explained as follows: Transparent allows
captions to come thru untouched for that field, Insert means that captions are being
encoded for that field, Opaque means that captions are being blocked for that field,
Newswire is a CC1 roll-up mode with a timed out bypass for field 1 only, and Monitor
means to re-encode the captions that are already there. Monitor can be used to clean
noise or chroma off the captioning insert.
There are three types of bypass’s that will show up on the display. They are:
Newswire Bypass, Software Bypass, and Encoder Bypass. Encoder bypass can only
be done from the front panel bypass button, as its name implies it bypass’s the encoder.
Software Bypass is a software command ^A0 or ^A7 this does not bypass the encoder
weather lift and XDS will still be encoded, a ^AS command, another encode mode, or
bypass button will get it out of software bypass. Newswire Bypass means that it has not
gotten any characters to encode with in its “time out” time. This puts Field 1 into a
Monitor mode, receiving another character, or changing encode modes will take it out of
Newswire Bypass. All three bypasses will light the bypass button.
Testing Unit will also show up on the display when ever the front panel test
button is pressed or the ^AT command is received. This encodes the pre-defined test
message (similar to the ^A? response) on CC1 and CC3 simultaneously. The unit does
a soft reset when the test message is complete.
Soft reset only resets encode, decode, and data recovery modes so there is no
glitch in the video. Hard reset resets I/O format, baud rates, port selections, pedestal,
weather lift, TSID, call letters, encode, decode, and data recovery modes. Likely there
will be a glitch in the video. Both resets will return back to the Main Display.

do what the command tells the unit to do. This is the default setup and normal
operation of the unit.
Remove control “A” codes, means that the unit will ignore the control “A”
command and do nothing with it. You would use this mode when encoding captioning
data that has been recovered from another video stream.
Pass control “A” codes, means that the unit will ignore the control “A” command
and encode it if encoding is enabled. You would use this when encoding noncaptioning data.

makes the software instruction set appear on the pc screen.
PTC-892 version 1 C 29
PTC-892 SOFTWARE INSTRUCTION SET
Version 1 A
The PTC-892 can execute instructions received via computer link. These
instructions are referred to as “Encoder Directives” in order to distinguish them from
standard Closed Caption “command codes”. They enable a computer operator to
control the operation of the encoder. Each Encoder Directive is listed below along with
its hexadecimal equivalent and a brief description of its function.
Encode modes
ENCODER
DIRECTIVE HEX FUNCTION
^A0 01 30 Software bypass on: This mode only allows weather lift and
XDS to be encoded all other information passes untouched.
Front panel display will show “SOFTWARE BYPASS”, and
bypass switch will be lit. To return from software bypass
mode, use the “Software bypass off” directive (^AS), use the
front panel bypass switch, or select another encode mode.
^A1 01 31 Field 1 Insert, Field 2 Opaque: This mode allows encoding
on Field 1 while all information on Field 2 will be removed.
This mode should not be used if useful information is known
or suspected to be present at anytime on Field 2.
^A2 01 32 Field 1 Opaque, Field 2 Insert: This mode allows encoding
on Field 2 while all information on Field 1 will be removed.
This mode should not be used if useful information is known
or suspected to be present at anytime on Field 1.
^A3 01 33 Field 1 Insert, Field 2 Transparent: This mode allows
encoding on Field 1 while information already on Field 2 to
pass un-touched.
^A4 01 34 Field 1 Monitor, Field 2 Insert: This mode allows encoding
on Field 2 while information already on Field 1 to be reencoded. If no information is on Field 1, the PTC-892 inserts
run-in clock and null bytes.
^A5 01 35 Field 1 Transparent, Field 2 Insert: This mode allows
encoding on Field 2 while information already on Field 1 to
pass un-touched.
^A6 01 36 Field 1 Insert, Field 2 Monitor: This mode allows encoding
on Field 1 while information already on Field 2 to be reencoded. If no information is on Field 2, the PTC-892 inserts
run-in clock and null bytes
PTC-892 version 1 C 30
PTC-892 SOFTWARE INSTRUCTION SET (continued)
Encode modes (continued)
^A7 01 37 Software bypass on: This mode does the same thing that
^A0 does.
^A8 01 38 Field 1 Transparent, Field 2 Transparent: This mode allows
information already on Field 1 and Field 2 to pass
un-touched. This is the factory default encode mode.
^A9 01 39 Field 1 Monitor, Field 2 Monitor: This mode allows
information already on Field 1 or Field 2 to be re-encoded. If
no information is on Field 1 or Field 2, the PTC-892 inserts
run-in clock and null bytes. This mode is good for removing
noise and chroma from line 21.
^A: 01 3A Field 1 Opaque, Field 2 Opaque: This mode blocks all
information already on Field 1 and Field 2, and inserts run-in
clock and null bytes.
^ANx 01 4E Field 1 Newswire Mode, Field 2 Transparent: This mode
accepts a simple ASCII feed and the encoder itself inserts
Field 1 command codes for three-line roll-up captions, while
information already on Field 2 to pass un-touched. A
“time-out” feature will insert the “erase displayed memory”
command code after “x” seconds without a new input. (“x”
may be any number from three through fifteen. For numbers
greater than nine use hexadecimal letters A through F.
Default time is fifteen seconds.) To exit Newswire mode,
you must put the PTC-892 into a different encode mode.
^AR 01 52 Soft Reset: A soft reset of the PTC-892, by loading default
values for encode, decode, and recovery modes also clears
XDS RAM, without causing glitches in the video. This will
not reset I/O formats, bauds rates, pedestal, or weather lift
like the hard reset does.
^AS 01 53 Software bypass off: Returns the PTC-892 to the last
encode mode before Software bypass on (^A0) was selected.
Changing encode modes will also accomplish the same
thing.
^Anx 01 6E Field 1 Newswire Mode, Field 2 Transparent: This mode is
the same as ^ANx except that this is a two line roll-up
caption mode.
PTC-892 version 1 C 31

PTC-892 version 1 C 32
PTC-892 SOFTWARE INSTRUCTION SET (con’t)
Miscellaneous Instructions
^A? 01 3F Vendor and Version Inquiry: This directive is recommended
by EIA-608 to facilitate remote captioning. In response to
the “control A, question mark” inquiry, the PTC-892 sends
the following message back to the computer operator:
Link Electronics Inc.
Model number: PTC-892
Firmware version: X X
^AO 01 4F Hard Reset: The PTC-892 loads all of its default values and
does a hard reset. It loads values for I/O format, baud rates,
port selection, pedestal, weather lift, TSID, call letters,
encode, decode, and recovery modes. It then performs a full
reset similar to start up.
^AP 01 50 Disable Odd Parity: Stores the incoming data without adding
the “odd parity” bit typical of Closed Caption data. Useful for
data transmission unrelated to Closed Captioning.
^AQ 01 51 Disable Byte-Pair Doubling of Command Codes: While
Closed Caption command codes are typically transmitted
twice in successive video frames, this directive will cause
them to be transmitted only once. Useful for data
transmission unrelated to Closed Captioning, or to possibly
allow compatibility with captioning software which could
double the command codes before transmission to the
encoder via RS-232.
^AT 01 54 Test: This is used to test the encoder by encoding a test
message (similar to the ^A? response) into the CC1 and
CC3 data channels. Then the unit performs a reset (^AR).
^AU 01 55 Send time code: The PTC-892 responds by sending the
current time code out. Time code is four hexadecimal values
that represent Hours, Minutes, Seconds, and Frames. 20
hexadecimal is added to the values so they aren’t confused
with encoder directives or caption codes. Example when the
output in ASCII is #D7% which equals 23 44 37 25 in
hexadecimal, now subtract 20 hexadecimal from those
values and you get 03 24 17 05. The time code sent was
03:24:17:05.
PTC-892 version 1 C 33
PTC-892 SOFTWARE INSTRUCTION SET (continued)
Miscellaneous Instructions (continued)
^AVx 01 56 V-chip: This mode accepts a simple ASCII string via and
inserts the data packets into the XDS RAM. A carriage
return will start XDS, meaning that it start encoding XDS.
Existing Field 2 Line 21 data is regenerated and multiplexed
with new XDS data from the RAM. ^AV1 clears XDS RAM
and enters XDS mode. ^AV0 clears XDS RAM and exits
XDS mode.
^AWx 01 57 Software weather lift lines: This mode allows you to select
the number of lines to lift captioning so that the weather
scroll and captioning can be seen at the same time. X = 0
thru 4. The PTC-982 will lift the captioning 1 thru 4 lines
when the GPI is closed. ^AW0 will turn off the command
control of weather lift and allow lift lines to be controlled by
the front panel.
^AXx 01 58 Need time code trigger: Returns a software trigger when a
certain time code is reached. Example if you wanted your
software to start encoding at time code 01:34:21:15, then
you would have your software send the PTC-892 this
command: ‘^AX!TA5’ or 01 58 21 54 41 35 then a carriage
return and your software would wait to send out encode
commands until it received a ‘T’ or 0x54.
^AY 01 59 Set power up default: This mode allows the user to program
the default conditions for decoding, encoding, data recovery,
TSID, and call letters. This option can be performed at
anytime once the unit has been powered up. When in the
default menu the PTC-892 will not respond to any other
commands including the front panel.
^AY 01 5A View help screen: The PTC-892 responds to this command
by sending out a help screen that summarizes all the
encoder directives for this unit.
^G 07 Send time code: This is the same as ^AU except encoder
must be in Field 1 insert mode.
PTC-892 version 1 C 34
PTC-892 MODEM FCC DOCUMENT
Changes in Attestation Procedure for Plugs and Jacks:
Link Electronics, Inc., attests that the network interface plugs or jacks used on
this equipment comply with and will continue to comply with the mechanical
requirements specified in Part 68, Sub-part F, specifically the dimensions, tolerances,
and metallic plating requirements. The compliance of these connectors will be assured
by purchase specifications and incoming inspection. Documentation of such
specifications and/or inspections will be provided the FCC within 30 days of their
request for same.
Type of Service:
The PTC-892 is designed to be used on standard device telephone lines. It
connects to the telephone line by means of a standard jack called the USOC RJ-11C.
Connection to telephone company provided coin service is prohibited. Connection to
party lines service is subject to state tariffs.
Telephone Company Procedures:
The goal of the telephone company is to provide you with the best service it can.
In order to do this, it may occasionally be necessary for them to make changes in their
equipment, operations, or procedures. If these changes might affect your service or the
operation of your equipment, the telephone company will give you notice, in writing, to
allow you to make any changes necessary to maintain un-interrupted service.
In certain circumstances, it maybe necessary for the telephone company to
request information from you concerning the equipment which you have connected to
your telephone line. Upon request of the telephone company, provide the FCC
registration number and the ringer equivalence number (REN); both of these items are
listed on the equipment label. The sum of all the RENs on your telephone lines should
be less than five in order to assure proper service from the telephone company. In
some cases, a sum of five may not be usable on a given line.
If Problems Arise:
If any of your telephone equipment is not operating properly, you should
immediately remove it from your telephone line, as it may cause harm to the telephone
network. If the telephone company notes a problem, they may temporarily discontinue
service. When practical, they will notify you in advance of this disconnection. If
advance notice is not feasible, you will be notified as soon as possible. When you are
notified, you will be given the opportunity to correct the problem and informed of your
right to file a complaint with the FCC. Contact your telephone company if you have any
questions about your phone line.
In the event repairs are ever needed on the PTC-892, they should be performed
by LINK Electronics, Inc., or an authorized representative of LINK Electronics, Inc.
PTC-892 version 1 C 35
What are TSID and PSID?
What is TSID?
Transmission Signal Identifier (TSID) is a 16-bit packet contained within the
Extended Data Services (XDS) of the EIA-608B specification. Each television station is
assigned a unique TSID assigned by the FCC. The TSID code is inserted into the TV
Station video signal. The recent FCC mandate, states that the TSID ID packet must be
presented in the broadcast station’s NTSC signal if the station chooses to have PSIP
guide information.
The FCC has emphasized that when the NTSC channel is announced in PSIP,
the transmission of the NTSC TSID in line 21, field 2 (XDS Channel) of the NTSC
broadcast signal, is now mandatory.
In other words, to ensure proper operation of digital TV Sets, the TSID data
within the NTSC signal must be present. Digital TV Sets will compare the TSID
information in the PSIP with the TSID information in the NTSC broadcast signal,
verifying that the NTSC signal referenced in the PSIP is actually the desired signal.
What is PSIP?
The Program and Systems Information Protocol (PSIP) is the ATSC standard for
digital television channel naming, numbering and navigation. DTV Receivers use PSIP
information to tune and label digital and analog channels.
PSIP is data that is transmitted along with a station's DTV signal that tells DTV
receivers important information about the station and what is being broadcast. The most
important function of PSIP is to provide a method for DTV receivers to identify a DTV
station and to determine how a receiver can tune to it. PSIP identifies both the DTV
channel and the associated NTSC (analog) channel. It helps maintain the current
channel branding because DTV receivers will electronically associate the two channels
making it easy for viewers to tune to the DTV station even if they do not know the
channel number.
In addition to identifying the channel number, PSIP tells the receiver whether
multiple program channels are being broadcast and, if so, how to find them. It identifies
whether the programs are closed captioned, conveys V-chip information, if data is
associated with the program, and much more. If broadcasters do not include properly
encoded PSIP data in their DTV signals, receivers may not correctly identify and tune to
the station. Therefore, it is vital that all broadcasters understand PSIP and include the
data in their DTV stations signals. PSIP is a mandatory Advanced Television Systems
Committee (ATSC) Standard.
PTC-892 version 1 C 36
What are TSID and PSID (continued)
Where in the Video Signal is TSID located?
TSID is contained within the XDS information of Field 2. The XDS channel
provides the TV viewer information about mature program content, station identification,
and program ID, and other information. In the Digital TV world, the TSID information
resides in the PAT table. The PAT Table (Program Association Table identifies MPEG-2
programs in a transport stream). The TVCT table (Terrestrial Virtual Channel Table)
identifies and describes virtual channels.
Who Needs TSID?
All NTSC and DTV licensees. The FCC urges all TV Stations to implement their
TSID’s quickly. All stations are required to comply with the TSID assignment number
without delay in order to not impede the roll-out of the DTV service.
How Do You Insert The TSID Code?
The Link Electronics closed caption encoders that support the insertion of the
TSID Codes in the XDS Channel are; PTC-892, PDA-895, and ENC896. These three
models are designed for analog and SDI. These units retain TSID and/or call letters in
non-volatile memory. A PC (Personal Computer) is not required to run the software as
other companies require.
These models supports insertion of TSID and/or call letters data into the analog
composite and SDI broadcast video signal. The units will re-generate Closed Captioning
and Current XDS data from the input video signal and insert the local station's TSID and
/or call letters into Line 21, Field 2. The TSID Encoders include an automatic process to
maintain compatibility with existing V-Chip captions.
The Link Electronics Closed Caption Encoders use the EIA-608 XDS standard for XDS
encoding. This includes the TSID information and Station Call Letters. All other XDS
data is displayed such as Program name, Program type, V-chip rating, Program
description, Network name, Station ID, Time of day, Time zone, Closed Captioning, and
Text Channels.
