PART ONE
Please Note:
This manual applies to both the MCG-3 Color Micro Character
Generator and the RCG-3, a remote control only version of the
MCG-3. All statements in this manual apply to both units unless
noted otherwise.
Introduction:
The MCG-3 is a low cost character generator for adding titles or
captioning to NTSC Color or Monochrome video. The MCG-3 will
automatically Genlock to NTSC inputs with no adjustments or switch
settings required. The MCG-3 outputs color characters, appropriate for
logging and documenting experiments, video source I.D., camera and
location display for security applications, time and date stamp from a
PC (or the MCG-3 with the real time clock option), Patient monitoring,
Information displays, and basic CG applications. The MCG-3 can be
operated in stand-alone mode without an incoming video signal.
The unit displays a maximum of 240 characters (10 lines by 24 letters).
Characters may be set to 4 widths and 4 heights for a total of 16
character sizes.
The character set includes both upper and lower case letters A–Z and
a–z, numerals 0–9, and various punctuation marks and symbols as
shown in the MCG-3 character table. Characters may be set to one of
seven colors or transparent and can be made to flash. The character box
or background behind the characters may also be set on a page by page
basis.
The display memory holds 10 pages of text and is protected from
power loses by a lithium cell that should last 8 to 10 years. Stored on a
page by page basis for each page is: the character size, display position,
background and letter color status, and the position of the Real Time
Clock Display.

Page 4
The MCG-3 may be controlled by either front panel controls or
remotely by an RS232 link to a PC, the RCG-3 is remote control only.
Multiple units may be chained together with standard RJ11 modular
telephone cable and individually accessed from a PC. Easy to use two
letter commands are sent to the MCG-3 from a PC running a terminal
emulation program (such as Qmodem or Procomm), from Windows
Run Terminal, or from user written software.
The MCG-3 has 3 LEDs: Power, RS232 Activity (Remote), and OnLine status.
About This Manual:
This manual is divided into three sections. Section One is a tutorial and
describes initial setup and MCG-3 front panel operation. Section Two
describes how to remotely control one MCG-3 or a network of MCG3’s from a Personal Computer. Also included in Section Two is a
reference section describing how to use each of the two letter remote
control commands. Section Three has information on specifications,
troubleshooting etc.
When reading the next section, the Tutorial, it is best to have the MCG3 in front of you to get a full understanding of the operation of the
MCG-3.
Material Supplied:
In the shipping carton you should find:
1 MCG-3 Color Micro Character Generator
1 AC adapter 12 Vdc/500mA
1 Operations manual
1 Three foot modular telephone cable (RJ11 Type)
1 DB-9 (RS232) to RJ11 (Telephone cord) adapter
1 Floppy Disk (Containing example software for remote control)
3MCG-3 Color Micro Character Generator
Page 5
Operation:
Power up the MCG-3 using the AC adapter or an external source of 12
Vdc. The MCG-3 has an auto polarity feature for the DC input
(polarity is unimportant). Connect a video source (black burst, VCR,
live video, etc.) to the VIDEO-IN BNC connecter. Connect the
VIDEO-OUT BNC connecter to a composite monitor. The RS232 host
and loop RJ11 connectors will be discussed in Section Two.
The RJ11 connectors are for remote control of the MCG-3 from a PC
computer RS232 port, and not for direct connection to a telephone
system.
Switch the unit on. When the unit is powered up it goes to On Line
status and displays the page it was set for the last time it was powered
up. The Green POWER LED and the red ON LINE LED should glow.
The page will appear blank if there is no text present. (If no text is
displayed and the page is not blank or if the green Power LED is
flashing, see the section on troubleshooting.)
The following section applies to the MCG-3 only and not the RCG-3.
The RCG-3 does not have any front panel control switches. It is
designed for remote control applications.
The MCG-3 may be controlled either by front panel controls or via an
RS232 link to a PC. This section will discuss front panel control.
(Remote control via a PC is discussed in Section Two.)
Front panel controls use menus on the screen to guide the user in
editing text or setting options. There are 4 menus:

Remote Control Tutorial
WARNING!!! – DO NOT CONNECT YOUR
MCG-3 UNIT TO A TELEPHONE SYSTEM.
DAMAGE WILL RESULT AND YOUR
WARRANTY MAY BE VOIDED.
The RJ11 connectors are for remote control of the MCG-3 from a PC
computer, and not for use with the telephone.
Your MCG-3 may be controlled from a PC computer via the
computer’s RS232 (serial) port by sending the MCG-3 simple two
letter commands (See the command reference for more information on
commands).
We provide:
1 RJ11 cable (36 inch)
1 DB9 to RJ11 adapter (DB25 to RJ11 also available)
You will need the following:
1 PC computer with a RS232 Serial Port
1 terminal emulation program such as Qmodem or Procomm
(ANSI.SYS compatible). From Windows, run Terminal; from Windows
95, select HyperTerminal.
You will need to determine if you have one or two RS232 ports, and
CC

Networking:
Your MCG-3 may be used as a stand alone unit, or in a network of
linked MCG-3’s. Networking allows more than one MCG-3 to be
controlled from a single PC computer, over a single RS232 link.
A MCG-3 network is much like the a telephone party line, where each
subscriber may listen in but only one person is allowed to talk at any
one time. Because of this, each MCG-3 may be put to sleep or woke up
and in this way only one MCG-3 will talk at any one time.
Each MCG-3 in a network is assigned a unique ID number. (See “Set

The ID on the RCG-3 must be set before the units are connected as a
network.

Notes On Cables:
Your MCG-3 uses standard RJ11 modular telephone cable. This type of
cable was chosen because of its low cost and ease of use.
RJ11 cable (with connectors) is widely available in various lengths, or
customs lengths can be fabricated. You can make you own cable (Radio
Shack stocks cable, connectors, and the crimping tool), or often a
telephone supply house can fabricate custom length cables.
The cable has four conductors and uses four conductor RJ11
connectors. The connectors should be attached so as to have the
locking “snap” tab facing the same way on both ends of the cable. See
Figure One or use the sample cable that came with your MCG-3 as an
example. Some cable has a rib along one side to aid in orienting the
connectors.
EE
E
EE
Connecting the MCG-3
To connect several MCG-3’s together, proceed as follows:
Run an RJ11 cable from the PC computer to the RS232 HOST
connecter on the first MCG-3. Next connect another RJ11 cable from
the RS232 LOOP connecter on the first MCG-3 to theRS232 HOST
connecter on the next MCG-3. The process repeats for all MCG-3’s on
the network. See Figure Two.
14MCG-3 Color Micro Character Generator
Page 16
The RJ11 cabling should be a direct connection from one MCG-3 unit
to the next. Do not use “Y” connectors or try to double up units. Also
the computer MUST be first in line on the network.
If the layout of a building is such that the computer should be in the
middle of the cabling, you might want to split the network between two
COM ports on the computer. See Figure Three.
Video Cabling
Video cabling is set up a bit different than the RJ11 cables. If multiple
MCG-3s will be using the same video source, then a video DA, such as
the Burst Model VDA-4 or VDA-8, must be used between the video
source and the MCG-3s. The MCG-3 VIDEO-OUT connecter is
connected to a video monitor. The monitor should be terminated in 75
ohms.
If the MCG-3 units will use separate video sources, then connect each
video source to its MCG-3 and the VIDEO-OUT of the MCG-3 to its
video monitor.
15MCG-3 Color Micro Character Generator

COMMAND REFERENCE:
Your MCG-3 may be remotely controlled by sending two letter
commands. The commands in this section are listed in alphabetical
order.
All commands have the same basic format, as follows:
CC
C,X, YC,X, Y
C
C,X, Y
CC
C,X, YC,X, Y
CC
Where:
XX
X and
XX
Parameters are information the command needs to operate. These may
be page and line numbers or something else. Parameters may be one or
two characters long. Some commands take one parameter, others take
two, and some don’t use parameters at all.
An example:
The following command,
MCG-3 memory:
WW
W
WW
This sequence will write THIS IS A TEST to page 8, line 3 of the
MCG-3.
To display the page that has this line, use the
command:
DD
P,8P,8
D
P,8
DD
P,8P,8
In this case we used only one parameter.
To get started, first be sure to read the remote control tutorial and
WW
W
WW
get familiar the remote control commands. If you will be controlling
your MCG-3 manually then you will simply send the MCG-3
commands with a communications program. If you will be writing
CC
C

FORMAT:
DESCRIPTION: After loss of input video is detected, a preset delay
can be set before the page of text defined by the
command is displayed. This applies only if the
command is set “ON”
the unit. Code 1 (white noise) is used when, upon loss of video, the
input becomes white noise such as loss of signal from a satellite feed or
the end of a tape on a VCR. Special software within the unit analyzes
the noise to determine if valid video (sync) is present or if it is just
random noise.
PURPOSE: Displays a page, in the MCG-3 memory, on the screen.
FORMAT:
DESCRIPTION: The MCG-3 holds 10 pages of text. This command
copies any one page to the screen. The contents of the pages in memory
are unaffected.
If the character size for the page is larger than size 1 vert., 1 horz., only
a portion of the page may be displayed. (See the CS, character size,

PURPOSE: Sets the position of the page on the screen.
FORMAT:
DESCRIPTION: This command sets the horizontal and vertical
position of a page on the screen. The page position may need
adjustment after changing a character size, or you may want to position
text over an object on the incoming video (such as redoing a telephone
number on a commercial).
The numbers used to specify the vertical and horizontal positions are
arbitrary. For the MCG-3 (but not the RCG-3), probably the best way
to determine what position you may want, for a given situation, is to
manually adjust an MCG-3 to the position you want, and use the
numbers on the screen (in the
this command.

PURPOSE: Runs diagnostic tests from a remote location.
FORMAT:
DESCRIPTION: This command is exactly the same command used in
the utility menu and as such it displays the results of the tests on BOTH
the MCG-3 screen and the PC screen. The results of the RS232 loop
test are not sent to the PC as a loop plug can not be installed while the
PC is connected to the MCG-3. However, if you would like your
software to be able to conduct the RS232 loop test, simply echo back
all characters sent by the MCG-3 after the results of the ROM test. The
test string sequence, in ASCII, is as follows:
(space)1234567890(space)abcdefghijklmnopqrstuvwxyz
(space)1234567890(space)ABCDEFCHIJKLMNOPQESTUVWXYZ
Spaces are 32d (ASCII).
Possible results of the RAM and ROM tests are as follows:
Testing RAM...(space)RAM Test Passed!
Testing RAM...(space)RAM Test Failed.
Testing ROM...(space)ROM Test Passed!
Testing ROM...(space)ROM Test Failed.
Each line ends with a carriage return (13d), linefeed (10d).
One easy way to interpret the results of the tests is to look for either a
period or an exclamation point just before the carriage return, line feed.
The results of the diagnostics test will flash momentarily on the video
screen, then the video will return to the last page displayed. The results
will be maintained on the PC screen.

PURPOSE: Reads one line from the MCG-3 memory.
FORMAT:
p = Page number 1 through 10
1 = line number 1 through 9
DESCRIPTION: This command reads any line in the MCG-3 memory,
given the page and line number. Results are in ASCII. However, if a
character is displayed in bold (meaning BG-Background is On) or is
flashing, the corresponding ASNI.SYS codes will also be sent.
Codes are defined as follows:
FunctionANSI code
Bold onESC[7m
Flash onESC[5m
All attr. offESC[0m
Note that ESC is ASCII code 27d.
EXAMPLE: If the string THIS IS A TEST is in the MCG-3 memory at
page 1, line 1 and the word IS is flashing the sequence read by the
command
THIS ESC[5misESC[0m A TEST
followed by a carriage return (13d), and line feed (10d).
If there were no flashing or bolded characters the sequence read would
be
THIS IS A TEST
again followed by a carriage return (13d), and line feed (10d).

PURPOSE: Turns responses from commands on or off.
FORMAT:
x = 2 “>” prompt
x = 1 Responses on
x = 0 Responses off
DESCRIPTION: When responses are set to off, the corresponding unit
will not send ANY data to the PC but will still accept commands. Also,
the MCG-3 front panel controls become inoperative. There are
basically three situations where you might want to use this command.
First, if you want to send commands to more than one unit at a time
(see the example below). This way, the units on the network won’t try
to all talk at once. Second, if you want to send commands at high speed
(9600 baud - no wait between characters). Because the unit won’t have
to spend time echoing back received characters or processing the
signals from the front panel controls, it will have more time to process
incoming characters at high speed. The third situation is to lockout the
front panel controls on the MCG-3 to prevent unauthorized use.
Set RSet R
If
Set R
Set RSet R
the unit will only respond with a “>” prompt. The purpose of this is to
allow for faster data transfers at 9600 baud (although you can use other
baud rates). The “>” character acts as a line pacing character. When the
unit receives a line of data, after processing that data and when the unit
is ready to receive more data, the unit will send a “>” character. At this
time the unit is ready for another line of data. This method of data
transfer is compatible with most terminal programs that support ASCII
data transfers.
If for some reason your software should miss the “>” character (line
noise, etc.), the unit will not send another “>” character. Your software

should time out and try to resend the line of data in this case. Also, the
first line sent should be a blank line (only a carriage return/line feed).
After sending the blank line, you should look for the “>” character.
This has two purposes: first, it will clear the unit’s serial buffer, and
second, you can confirm that the unit is in response mode 2.

The RTC (Real Time Clock) option for the MCG-3 allows the MCG-3
to maintain the date and time of day, and displays these on the video
display. Time keeping is battery backed so the RTC will maintain time
and date information when power to the unit is off. The RTC maintains
date information as follows: month, date, and year. Leap year is
detected and corrected for on leap years. For time information the RTC
maintains hours, minutes, seconds and AM/PM status. The RTC will
work in miliary time (24 hour format) or standard time (12 hour
format).
Installation:
The RTC option is a small printed circuit board that installs on the
inside of the MCG-3. Proceed as follows:
1. Turn off the power to the MCG-3.
2. Remove the two screws on the face of the unit.
3. Remove the front panel.
4. Slide the top cover forward and remove.
5. Locate the lithium battery. It is positioned towards the front of
the unit, it is silver, about the size of a quarter, and is sitting in a
black holder. Directly behind the lithium battery (looking from
the front of the unit) is a black connector with 20 holes. This is
the connector for the RTC.
6. Remove the RTC board from its plastic page. Note, to avoid
damaging the RTC and the MCG-3 by static electricity, be sure
to electrically discharge yourself before removing the RTC
board from its bag.
7. With the power off, insert the RTC into the black 20 hole
connector, long end toward the rear of the MCG-3. (You should
still be able to see the lithium battery after the RTC is installed.)
59MCG-3 Color Micro Character Generator
Page 61
Be sure that none of the pins bend, and that all of the pins and
connector holes line up, assuring that there is no misalignment.
8. Reassemble the unit being careful not to over tighten the
screws. (Do not tighten more than 1/8 turn past seated)
Setting the RTC (Real Time Clock):
RCG-3: Set the RTC using the remote commands

TROUBLESHOOTING & FLASHING LED’s:
Your MCG-3 was designed to be reliable and easy to operate, and
features RAM Memory Error Detection. If an error in the battery
backed RAM memory should occur, (may be caused by the internal
battery being run down after a loss of AC power or by a glitch on the
AC power line) the POWER (green) LED will flash rapidly indicating
the error.

The
flashing POWER LED condition is not detectable by remote control.
The reason for this is that the serial baud rate information is stored in
battery backed RAM, if the RAM contents have an error (the RAM
scrambled) then the baud information is likely to be wrong, in which
case serial communication would not be possible.
If your MCG-3 should not function as you think that it should, try
switching the power off and on again. Also you might try a

If you are writing your own software, the MCG-3 may be reporting
errors that you don’t know about (your software may not read response
information or responses have been turned off). One thing that is highly
recommend in writing your own software, is to run a communications
program on the PC computer, execute the commands that you think
might be giving you trouble one by one, and see what responses
(errors) come from the MCG-3. Executing the commands one by one
also gives you a chance to see what exactly the MCG-3 does and/or

BATTERY REPLACEMENT:
Your MCG-3 uses a Lithium watch battery (BR2325 or equivalent).
This battery should last 8 to 10 years. Battery replacement is indicated
by one or more of the following:
1. A “flashing power LED” condition whenever the unit is
powered up.
2. Time and date (with the RTC option) and buffer information is
not correctly maintained when power is off for any length of
time.
3. Baud rate and other settings not correctly maintained when
power is off.
If you take care in replacing the battery, with the Power On, then none
of the stored data will be lost.
To replace the battery, proceed as follows:
1. Remove the two screws on the face of the unit.
2. Remove the front cover panel.
3. Slide the top cover forward and remove.
4. The battery is silver, about the size of a quarter, and is sitting in
a black holder. Using a small screwdriver, gently remove the
battery, being VERY careful not to over bend the metal tab
holding the battery in place.
5. Locate the plus symbol (+) on the new battery and insert the
new battery plus (+) side up. BE VERY CERTAIN THAT THE
PLUS (+) SIDE IS UP.
6. Reassemble the unit being careful not to over tighten the
screws. (Do not tighten more than 1/8 turn past seated) The
battery may be replaced with the power on to maintain the
buffer data, and date and time (with the RTC option).
