MULTI
LINE LED DISPLAYS
Multi Line LED Displays
have the ability to display larger amounts of information per page
compared to single line displays. A page is what the LED displays
are able to show at any one time. A double line display will display
twice the amount of information as a single line display with the
same amount of characters per line. A four line display will be
able to display four times as much information as a single line,
and twice as much information as a double line display with the
same amount of characters per line.
The number of characters
an electronic display is able to show per page is equal to the number
of characters per line multiplied by the number of lines.
Max characters per page
= characters per line X number of lines

OPERATION / FEATURES
PolyComp Alphanumeric LED
Displays are easily programmable, with various methods of operation
to suit almost any application.
Keyboard Operation
 The
simplest way to program Alphanumeric LED Displays, is using the
standard PolyComp RMSP-100 Infra-Red Keyboard. The keyboard is simply
pointed at the display and the message is typed into the display.
PC Operation
PolyComp Alphanumeric LED Displays can also be programmed from remote
locations using PC's and Windows Compatible Software. The LED displays
can be connected to PC's in various ways:
- Connected directly to
a PC's Serial Communication Port
- Via dial-up modem
- Over Ethernet TCP/IP
network
Messages are then edited
and composed on PC and then downloaded or sent to the display.
PC Operation is particularly
effective when using multiple displays. Each display can be given
its own identity and messages specific to it can be downloaded from
the PC software, without affecting the other LED displays in the
system.
NOTE: For custom applications,
or when the LED displays are used as part of another system, PolyComp
will supply the Serial Communication Protocol Technical Specifications,
for 3rd party development.
Features
Transition Functions: - There are 15 attractive transitional
functions including: - Appear, Wipe, Open, Lock, Rotate, Right,
Left, Roll Up, Roll Down, Ping Pong, Fill Up, Paint, Fade In, Jump,
Slide.
Tempo: - This is the time duration that each page is displayed
for. 9 different tempos are available.
Pre-Scheduling: - Each page programmed into the display can
be scheduled to display at a specific day, date & time.
Auto Centering: - The text entered into the display is automatically
centered, providing a symmetrical, visually appealing display.

Month, Day & Time on the display.
Back-up battery: - No loss of memory or time in case of power
failure.
Enclosure: - Aluminum extrusions, powder coated for durability
and functional ergonomic design.
COMMUNICATION
OPTIONS
- RS232 - Connected directly
to the serial communication port of a PC. The cabling is limited
to a maximum of 50 meters between the PC and the display.
- RS232 is suitable for
single display applications with short cable lengths.
- RS485 - Connected to
the serial communication port of a PC via a RS232 to RS485 converter.
Suitable for use in connecting many signs together on the same
cable with no conflicts, in electrically noisy environments.
- Ethernet - Connected
directly into a TCP/IP 10BaseT Ethernet network, and assigned
its own IP address. Suitable for use where there is an existing
network infrastructure.
- Modem - Connected directly
to a modem that answers an incoming call from the PC operator,
and will disconnect after the message has been transmitted. Suitable
for use where there is an existing telephone line and other communication
options are unsuitable.
Upto 64 signs
can be connected on a single pair wires addressed individually or
"All Call".
ALPHANUMERIC
LED DISPLAYS
Description
Alphanumeric LED Displays are electronic (Light Emitting Diode)
displays used to display visual messages made up of letters, numbers
and special characters.
The main parameters describing
Alphanumeric LED Displays are:
- Number of Characters
Per Line - This is the number of standard sized characters that
each line of an electronic display is capable of displaying.
- PolyComp's standard character
per line models include:
- 16 characters ; 24 characyers;
32 characters & 40 characters.
- For special applications,
a specific number of lines per board may be requested.
Number of Lines -
This is the maximum number of lines the electronic display is ableto
display at any one time, using standard sized characters. olyComp's
standard number oflines include: 1 line, 2 lines, 4 lines, 6 lines
& 8 lines.
For special applications, aspecificnumberof lines per board maybe
requested.
NOTE: Difference between
a V1 and V2 board
A V1 board can only display standard height characters on each
individual line of a display. A V2 board has theflexibility to
join two lines of a display to create a bold type character that
is almost double the height of the standard sized character.
This means that a sign
that can display 4 lines with 24 characters per line and a character
height of 6mm, can also display 2 lines of 12 characters with
a height of 120mm.
Note - When the bold type character isused on aV2 board, the character
height almost doubles, whereas the number of characters per line
is halved due to the bigger width of the bold type character.
Character Height
- This is a physical measure of the height of a standard sized character
expressed in inches or millimeters.
PolyComp's standard character heights are:
Character height in inches* Character height in millimeters* Max
viewing distance of standard sized characters
- 1 30 8-10m
- 2 60 25-30m
- 4 100 40-45m
- 6 150 60-70m
- 8 200 95-110m
*
an indication, sizes have been rounded to nearest whole digit, actual
sizes may vary slightly.
