Each LED must have its negative connection (cathode) connected to one
numbered pins 1-64.
Each LED must also have its positive (anode) connection connected to
supply pins marked “+”. Note it does not matter
which of the “+” pins you use
as they are all connected together on the board.
You can daisy-chain
multiple LED + connections and connect to one + pin.

The PacLED64 is supplied with a power cable which plugs onto a spare PC

Also, connect the USB cable to a USB port on the PC.
Alternative Power Options
The LED power connector can be powered from another source such as a
wall-plug power supply. The voltage required depends on LEDs being used
but all LEDs supplied by Ultimarc require 5 volts and the supplied
power cable is pinned for 5 volts.
Current requirement is 0.02 amps X number of LEDs. Note each RGB LED
counts as 3 LEDs.
Ensure CENTER pin on the connector is 5V, BARREL is ground.
Connector is 5.5mm diameter. 2.1mm pin.
When you power on the PC, the board will immediately run a script which
is pre-loaded in flash. If you have overwritten this with your own
script, this will run. The pre-loaded script causes all LEDs to
sequence in a fade up/down “wave” from 1 to 64.
Scripts are repeated continuously.
When a command is sent by the PC via USB, the script stops running and
the command is processed. The script is then not run again until the

- Testing LEDs and connections
by turning LEDs on/off or setting to a specified brightness.
- Creating simple
“attract mode” scripts and storing in the on-board
- Assigning an ID to board,
when using more than one board
When clicked, all subsequent commands will be stored in on-board flash.
Next time the board is powered on, the script will run and loop forever
until a command is sent from the host via USB.
Clicking “Stop Recording” will end the script
This will cause any stored script to be deleted, so on next power-on,
nothing will happen until the host sends commands via USB.
This adjusts the time taken to perform a fade. A fade occurs whenever
the state of a LED changes, ie its brightness is changed or switched
off/on. This setting affects all subsequent state changes. This can be
stored in scripts.
Script Step Delay
This adjusts the time interval when scripts are being executed. This
can be stored in a script. This is not relevant when sending direct
commands from the host.
On this screen, the brightness of any of the 64 LEDs can be set. The
command is executed immediately by the board, and if you are storing a
script, is also added to the script.
On the latest version (requires latest firmware) the LED(s) can also be
set to flash at one of 3 rates on this screen.
On this screen, a group of 8 LEDs is set to a pattern. The LEDs are
either fully off or fully on. There are 8 groups of 8 LEDs. Also, all
LEDs can be set to a random pattern.
The command is executed immediately by the board, and if you are
storing a script, is also added to the script.
Ultimarc LED and output controllers have great software support,
including PC and Linux software and our own SDK which enables easy
addition of output control to your own programs.
Also a Linux library is available. See our Programming

LEDs from your own
An SDK is available which includes a DLL to provide an API to enable
LED control in your programs. The SDK includes the DLL, plus example
source code showing its use. A test program for checking operation of
the DLL is also included.
The SDK is detailed on our PROGRAMMING PAGE
and SDK Support
As most third-party software and our SDK is cross-product, we have
placed all details on this page
